Consumer Electronics Review

complement the dark side of insufficient light

Shooting antiques, small sculpture, jewelry, stained glass, carved glass, plates, bottles, dolls, wood carvings, furniture, paintings and similar items, not only useful in the insurance industry, but also for creative photographers, but also a Rao interesting work.

(A) First, choose an appropriate lens. Ideally, large-diameter lens. Because it can avoid a lot of complex lighting equipment, to avoid the monotony of high-contrast flash effect, but also to avoid calculation errors caused by flash reflection. In general, F 2 or F1.8 lens, can make the shooting was carried out faster and better. Using a large diameter lens it should be noted that most are very limited. Approach is not to overcome the camera too close to the subject matter. Slower speed can also be used to shoot with a smaller aperture. But not slower than the minimum rate of 1 / 30 seconds, because of the speed and then slow to inevitable shock. Focus on the subject matter in the most important part, other parts can not focus. Bear in mind that when using a standard camera lens too close to the object, it will distort the image.
If you use a tripod, ideally one of about 135 mm focal length lens. This photo shoot, the proportion of the various parts of the object compared to normal. To the minimum aperture is best to make all of the subject matter can be clear.HP Compaq NX7400 battery
Wide-angle lens is ideal when shooting large pieces of furniture. It can be concave and the curved part of the furniture all looks very clear. This lens can also provide great depth of field, even at close range photography or when using the maximum aperture is also true.
Clap ornaments, coins, a class of small items, you can use the price is not too expensive, close-up lens attached. These lenses generally the standard lens can be screwed. Device equipped with a close-up telephoto lens, you can also shoot the same effect.

(B) of the small items of lighting, both can come from natural light through windows, you can also use the camera light, flash, or even candles and floor lamp, or a mixture of these sources of light. Meanwhile, the other side of the object, put up a large reflector to complement the dark side of insufficient light.
If you use only natural light outside the window, to avoid direct sunlight. There are windows on both sides to find a better corner, so you can use the sky diffuse light to light the subject to a three-dimensional. If both the indoor lights on or near the object to a two lamps color to enhance the main part of the light, an effect will be better. More appropriate to use two light photography. One of the brightest objects in one or closest to the side away from the camera, the other close to the camera. And then back behind the subject matter coupled with a spotlight, so that the subject matter outline appears around the wonderful light.battery Toshiba PA3420U-1BRS
Determine the intensity of light, preferably visual. Light and shadow should have a certain balance to avoid the contrast is too strong.

(C) Regardless of the film, black and white or color, the slower the speed, the more detail can be fully reflected in the object. However, when using color film, must take into account the color temperature of lighting. In the choice of film, you should also note that with the appropriate filter.
If you must use high-speed film can be sensitivity to ASA400 black and white film, to 1000 or higher sensitivity to use, and then washed with a special volume of particles developer, the subject matter of the film grain to would not be lost.

(D) precise metering is very important. Direct metering of objects the simplest method is to be edge-lit table on the physical assistance to move around (but be careful not to put into his shadow to the top), then the brightest star in the dark, and the average of at to exposure. For low light objects, such as the black statue, freshman level should be open aperture.Compaq tc4400 battery
Carved glass products should be placed in translucent plastic sheet or on a piece of frosted glass, the back lined with white background, and then lighting from below. In this way, we can highlight the objects crystal lines. If possible, use a soft plastic sheeting on the wall, the bottom of the pad under the cut glass to form a seamless traditional background.
Cloudy weather, light, slow fire, for many small items to excellent yields up effect. Put in the outdoor tables, the items on the table top to beat. This remake of weather on outdoor painting and photographs are very satisfactory. Exposure to a 18% reflective gray board determined. Most items that fit in simple and plain background. Smooth walls of the board, color board, bed sheets, velvet or other textiles can be used.
Jewelry should be based on its color, contrast and strong light on the dark board or surface, shooting from above.

Choose the right digital camera battery

[Q] Which should I choose the battery system

[A] in terms of capacity, lithium has no obvious advantage to speak of. We are evaluating the use of a large number of times to 2000mAh (iMax) nickel-metal hydride batteries, and general digital camera 1000mAh Li-ion ACER Aspire 5570 battery capacity of around often. Shooting data also illustrate this point, Fuji S602 and other “runners” has begun to catch up with Canon G3, Sony F717 record set. Ni-MH battery and using a common digital camera, you can buy at any time Emergency battery charger or charging at any time by someone else, very few embarrassing scenes from battery exhaustion. Using a dedicated charger, the charging time is often reduced to 4 hours, catching up with lithium battery. Ni-MH battery with plenty of energy and life of nearly 1,000 charge and discharge it to become the most cost-effective digital camera batteries.

In addition, the battery voltage is also a matter of concern. 5, the recent introduction of two digital camera battery more and more, this evaluation in the entry-level products are the basic configuration. Reduce weight and HP EliteBook 8530P Battery energy consumption is good, but in the same type of hardware platform, the high supply voltage can often bring a faster shooting and processing speed and higher image SNR. In EOS-1D/1Ds series on the use of 12V NP-E3 Ni-MH battery pack is a good example. Therefore, high-performance digital cameras with high-voltage battery pack or a period of time may be an inevitable choice.

Times the battery can be fully manifested 2000mAh Ni-MH battery low internal resistance, large current discharge characteristics, the flash charging speed, and high-speed continuous shooting, records video clips and never clear-cut. It also Ni-MH battery discharge curve with a APPLE A1181 Battery voltage stable, but the characteristics of the end of the rapid fall, once the LCD screen begins to prompt the lack of battery capacity, the remaining capacity will support only a dozen sheets of film. The dedicated charger with fast charging and smart charging features.

Prone to errors: the high energy density lithium batteries, small size, is the first choice for digital camera power supply.

Discussion: from the use of terms, digital camera viewfinder, exposure, image processing, playback and storage when they have different power consumption characteristics; from the main power devices to analyze, LCD screen, flash, image sensor and processing engine is power-hungry, but basically is unexpected type, only in the moment of the work of high current, usually quiescent current is very small. This determines the power consumption characteristics of a digital camera, you need to have a sudden high current power supply capacity. From this point of view, relatively low internal resistance of battery is more suitable for digital cameras, SONY NP-FH50 Battery digital cameras, it can significantly improve the response speed. The average charging time from the analysis of the flash, using lithium camera ahead, usually only 3 seconds, while the use of Ni-MH battery models tend to be longer than 6 seconds.

[Q] how to focus and increase the reaction rate

[A] to improve the focus and speed of response many ways. First, using the traditional single-focus approach will certainly improve the speed, because some of the focus assessment only a small part of the image data processing, reducing the time required to judge, but this will reduce the product’s ease of use; Secondly, the use of high-speed processors and improved evaluation algorithm is also very effective, but this will increase costs and reduce the HP Compaq Business Notebook 6910p Battery life; Third, similar to the Fuji Super CCD and Foveon X3 sensor can only read the latest sensor data in a given region, the source of the processing reduces the amount of data, improved processing speed, but unfortunately not very popular these sensors; Fourth, we can set the camera to increase outside auxiliary lens focusing system, you can not focus through the CCD, Fuji S602 and Ricoh RR30 is through this structure snapshot won a reputation, but the auxiliary focus system not only increases the cost and accuracy is often not as good as CCD … …

It seems to improve the focus and responsiveness of the digital camera is a very difficult problem that requires Compaq laptop battery manufacturers to costly research and development effort a better solution.

Myth: As an ordinary digital camera TTL-CCD focus is carried out by many people think that the higher the number of CCD pixels, can also be faster focusing speed.

Discussion: Because of an ordinary digital camera in focus CCD imaging signals must be read, focus and speed of response was the number of first-generation high-pixel digital camera never mind the pain. Increase means the number of pixels per CCD read signal also increased the amount of data, focus, metering, LCD display post-processing also carry a heavy burden. Therefore, we can often see the same HP Compaq 6710s Battery hardware platform based on digital camera series, the low number of pixels high product rate is often higher than the number of pixels of the “Big Brother.”

Landscape photography approach can be summarized as two words:

Landscape photography approach can be summarized as two words: knowledge, concept, list, and now (that is, knowing when the concept of the potential, indicate its quality, is the Wei).

1, knowing when

“Time” in the broad and narrow sense, respectively. Broadly speaking, refers to the seasonal spring, summer, autumn and winter. We all know, the nature and decorated colorful flowers and trees, their breeding, thriving, litter, all the changes with the timing of climate change. So beautiful scenery the same location,Dell Vostro 1000 laptop battery four seasons have different views of characteristics (such as Jiuzhaigou, Sichuan, Anhui, Huangshan, etc.), but also with the climate shift with the seasons and showed a different attitude and unpredictable. Even the clouds floating in the sky, are displayed in front of the spectacular wonders of depicting, and directly with the rain and the cloud is closely related to fog. These are the general picture of nature, but the shape of cloud and rain and potential, and indeed the different seasons. So you want to show the nature, but also with typical scenery, this generalized “time”, they can not refine analysis, in-depth understanding can be effectively and grasp the right time.

The narrow meaning of “time”, is the day from morning to evening, even at night. The most important condition is the source photography, and shooting by the light of the nature and scenery,battery for HP Compaq Business Notebook nx8220 but it is only sunshine. Therefore, should this only source of light, non-photographer is in charge, and to appropriate use. First, the direction of seasonal light source and may be projected onto the place and position to understand the ascent of the West generally only know the sun down, in fact, the direction of movements which are moving with the seasons, so the light changes also directly affect the screen the effect of the location of the winter sun is biased towards the south, and projection bias North; summer sun has rose from the north, south Shimoji is fired. Variation between the two locations are moving very little, as one year as the sun rises from the east, only two days (March 21 equinox, September 23 Autumnal Equinox), the daily change 0.258 degrees.

Have the effect of light on the scene, even if only a fine line difference, but all very different, then the only reliable shooting natural scenery of the sun, lifting its position on the projection of the direction, not only must be clear, and absolutely essential .

2, the view of its potential

Is observed throughout the environment and the shooting scene situation.price of Dell Inspiron Mini 9 battery You know, when we’re in the embrace of nature, across such scenes, already the twists and miscellaneous array, which should be deleted, that should be choice, as to adopt the position of King, the best angle is not a hasty decision can be made between . Therefore, we must carefully patiently, not tired of the trouble, fear their workers to and from any location and angle to explore. Deep view of the Mocha, combined with experience to select the ideal angle to shoot the scene in mind is to lay the draft, followed by addition to meticulous tailoring. The so-called window dressing cut to place the most also pay attention to, not negligence. Regardless of a grass with one stone, a leaf, needs to be included in the scope of scrutiny. Because the show for a long time in the open case seemingly insignificant things and no important place, when the perfect piece of work requirements, often plays a role in the construction and destruction of the extreme. Therefore, the election scene and taken to very detailed. Painter Huang Bin said: “vertical travel landscape, we must have vacated the dynamic days, but also to find a monk’s cassock static fill.” Means that the scene before we have a tremendous enthusiasm, tireless running around everywhere to observe, look for King, chief representative to follow is to think about, to understand the immediate landscape, to understand these views. Painters also says: “There are thousands peaks, so spectacular, it’s landscape ever such, there are hundreds of samples per individual.” Therefore, we observe the mountain, scenery, and not stay on the surface, HP Compaq Business Notebook nx8220 Replacement batterymore attention is the mountain views momentum with local characteristics, the Five Dynasties era painter Jing Hao said: “The search really wonderful record.” Miao is the objective reality, subjective search is the author’s efforts. These are the previous experience of artists, to teach us is a insult.

3, table the matter

Comes to the table its quality, we all know everything has its unique nature, particularly natural landscape shot, for the natural environment is full of flowers, grass, wood, stone, mud have to deeply understand the nature and familiar and grasp its essence, to effectively reproduce the images in the photo. Predicate in our photography thing so-called “texture” means that the texture of the scene or object in the performance requirements of the time, not only have the outline of its shape,EliteBook 2740w battery it is important to aim to have a qualitative sense of the performance of both bones, and meat.

4, view the magnificent

This “Wei” meaning the word is very broad, like the magnificent, extraordinary transmission and so on. Shooting mountains, towering trees, etc., they can use camera angles to go up to “Wai” the art of composition, comparative methods can also be set off to the “Wei” more highly visible. The “Great” in another sense, you can also extended to the United States, to give outstanding views of the most beautiful place is also now its “Wei” in a category. So, we took pictures on how to view the scenery, “Wei” mean? The key lies in grasping the characteristics of features, style.

Such as Huangshan, there are four characteristics: the sea of clouds,HP Compaq Business Notebook NX6140 laptop battery clouds, pines, rocks. But we have vision into a big place there each with wonders, each with three odd risk thirty-six Shiliu Da peak and small peaks; if the horizon a little place, many of melancholy gray of the forest to clear deep also The Rock Valley. Then sight back side, there are lots of free small scene, all in all, are based on ecstatic.

As the name Mount Emei, is dark green show, Castle Peak can be said to have a quiet and beautiful. As the saying is but majestic towering, rugged majestic it. Landscape under heaven known as known as Guilin, Yangshuo numerous even than Guilin, but also is the mountain Qiaoba, water clarity. Therefore, when we enter the great mountains and rivers, when the eye to their own and experience, but experience is the art of pre-cultivation, the lack of such training, it can not be found the most beautiful side scenery. Kinetic energy of camera lens used to collect all landscape features of special lenses can have a visit to get some kind of documentary.

To create digital teachers – Fun paper production
Copies of the template for papers
The so-called rainy day, make a paper template to future contingencies, should be very smart, save each system volume must do repetitive tasks. So before the system volume, we may wish to analyze a paper should be some content: left sealed, paper title, the results table, with the whole question of the rating items indicating the number of pages and page number footer area, as shown in Figure 1 show. With these, basically even have a “professional”, right? Now we take a look at how to make a such papers.
Figure 11. Page Setup is usually the papers we use are octavo paper horizontally divided into two columns. So, first click the menu command “File → Page Setup”, click on the “Paper” tab, set the paper size “on” or “B4,”. Click the “Margins” tab, left margin value is set too large, such as “4.5 cm, bottom margin is set to” 3 “cm other margins are set to 2 cm. Layout direction is selected as the “horizontal”. Click the Document Grid tab in the number of columns, the value is set to “2″, so that you can test paper is divided into two columns. In general, in two columns of the papers, we will be coupled with the separator between the columns. So, click the menu command Format → Columns to open the Columns dialog box, select the “separator” rehabilitation option.
Two. The production of papers sealed line click on the Text Box button on the Drawing toolbar, papers in drag, a vertical bar-shaped text box. Its height with papers body of the same height and width you do not have too broad, and can lay down a line of words can be. Double-click the text box border, open the “Format Text Box dialog box, click on one of the colors and lines” tab, text box fill color and line color is set to “fill color” and “wireless bar color. ”
This text box is selected, click its border, the border filled by a slash into a small point fill. Click the menu command Format → Text direction “in the dialog box that opens, select the direction of the left-most styles, shown in Figure 2. Determined, in the text box, type “Name ____ Examination ____” text, set the alignment to center.
Figure 2 “straight line” button and then click on the Drawing toolbar to add a straight line in the text box to the right side of seal lines (you can hold down the Shift key and drag). “Linear” button to select this entry straight line, click on the Drawing toolbar, assigned to linear and width (optional 2.25 pounds of a single solid line). Select the text box and a straight line, click on the Drawing toolbar, drawing → Combination “” command, they are combined into an object.HP Probook 4720s battery Press the “Ctrl + X” key will shear it to the clipboard.
Now, we can click the menu command View → header and footer, and the mouse position in the header area of ​​combination of good press “Ctrl + V to paste left seal area come. Its location on the left of the right place. Such papers in each one will be automatically added to the left of the seal area. Very convenient, right? However, the production is completed, do not forget the “Header” in the “Format” toolbar style to the text. Otherwise, the newly added one paper at the top will be a horizontal line, which is not what we need.
3. Indicate the number of pages and page numbers because of our papers are divided into two columns, so, we should be in each column below to add page numbers in order to avoid students missing subject. : Double-click the left column below the footer position, the footer edit mode. (Prohibition) a text box. The previous method, the fill color and border color for the text boxes are no color. Click on the border to enter the edit mode.
First enter the “page”. Positioning the mouse “and the word” page “in the middle, press CTRL + F9 key combination (Prohibition) domain of characters” {} “, where you can enter = {PAGE} * 2-1 . Pay attention to “{}” symbol can not be entered manually, only press “CTRL + F9 key combination. And then positioning the mouse in between the “total” and “page”, using the previous method, the domain characteristics of symbols, in which the input “= {the NUMPAGES} * 2″. Move the text box, enter the text exactly into the middle of this column.
Select text box, hold down the “Ctrl” key while using the mouse to drag it to the middle of the lower right-hand column. In this way, you can get one with just a text box identical to another text box. The field code = {PAGE} * 2-1 “replaced by” = {PAGE} * 2 “. Domain code in the text box is selected, right click and select “Toggle Field Codes” command in the shortcut menu. In each column so that you can see the effect of the “page x page x. To align the two-column footer text, select the two text boxes, click on “Drawing” toolbar “each other or distribution → Align Top” command.
4. The papers note of the partition and the production of the scoring area than the front part of the work is simply more. In accordance with their own ideas (Prohibition) form can be. Should be noted that the scoring area for each question in front of the table, we should select it, right-click in the shortcut menu, select “Table Properties” command, and then open the Table Properties dialog box, select ” Wrapping text around the way, and click the “positioning” button to the right, in the pop-up table positioning “dialog box, select the” with text “restore option. Shown in Figure 3.
Figure 3 papers used in the production process tools
We must first sharpen his tools. Production of the papers also have a good helper to do half and twice the A. Mathtype
Mathtype is a powerful mathematical formula editor, and use it,HP EliteBook 2760P battery we can easily enter all kinds of complex mathematical formulas and symbols, shown in Figure 4. It can save the edited formula into a variety of image formats, or transparent image format, you can easily add or remove symbols, expressions, and other templates (only need to simply use the mouse dragged out of the can). WYSIWYG, real convenient. You can download , @ ftp11.enet.com.cn: 88/pub/utility/teach/MathTypeSetup.exe at its 5.2 version. Support of this version of Word is very good.

A disadvantage of shooting in the indoor lighting is not ideal

A disadvantage of shooting in the indoor lighting is not ideal, in most cases, indoor light will be too dark. At this time, the flash is obviously a very effective artificial light, powerful, and the use of diversification, but you can also shoot the scene when the effective use of existing light.

Built-in flash of light is often too weak, too cold, the recorded image will destroy the atmosphere of the whole environment. When shooting at 3 meters away, you have to use the exposure index of at least 36 to 40 external flash – you can flash to the understanding of friends or photographic equipment dealer to use your camera with flash devices and their performance.price of compaq presario v3000 battery Need soft lighting, you can also flash on the camera’s set-top or lateral, while using reflectors and diffusers for the lighting soft, it is because it can enhance the effective lighting area, with a side light to photos bright three-dimensional objects.

Large room in the shooting, you can use multiple flash or play a large aperture, the release of different locations in the room the shutter – this approach will be very difficult, especially when you do not have photographic assistant.

You can also use artificial light to replace the continuous flash, tungsten halogen light and light is a good choice, if the camera’s automatic white balance setting does not make you be satisfied with the results, you may wish to try several different white balance settings, If you can not use additional artificial light, you can only use so-called \ “an effective natural light \”, and they may be light shining through the window, it may not affect the normal artificial light photography. The advantages of using natural light effectively lighting the room is very natural.

Unless you buy very cheap camera, otherwise you’d better choose the exposure time (determined by the shutter speed) in 1 / 500 to 1 or 2 seconds the camera, but can choose as many different aperture, the camera itself qualifications to enable you to shoot indoors in the dark possible, but also capture the effect was very good photos.

It is noteworthy, however, indoor shooting, it is best to turn off the flash, while the camera on a tripod, otherwise the picture will become blurred. There is no tripod, you should also be possible to find a stable anchor, these methods although there is not one good effect, but also appropriate because of the camera shake caused by the reduced image blur. When the shutter is released, the camera against a hard object – benches, pillars or walls, only thing is solid on the line, and then very gently press the shutter release button. If possible, self-timer can also be used to release the shutter.

In poor light or when shooting unstable environment (such as prohibiting the use of flash site),battery for NIKON en-el5 the only option is to increase the sensitivity, high-end cameras have \ “to force sensitization \” feature, you can from a series of ISO values choose from double or quadruple speed. However, this method will greatly affect the image quality. Which, of course, this is to avoid image blur caused by shaking the only way, especially in the free activities taking pictures or shooting when your subject is particularly useful.

When shooting photos of people in the room, we often use the built-in digital camera flash for fill light, but if not properly use flash light, often left behind in the main characters ugly shadow, seriously affecting the photos of the beautiful. So, how to avoid or reduce the occurrence of this phenomenon flash shadow of it?

Let people as far away from the wall or object

Projection based on the principle of light, when characters from the walls or behind objects closer, the interior lights and the original can not be irradiated or reflected natural light to the people behind the walls and other objects, when a strong light flash light, it will be taken so that people behind the walls and other objects left on the heavy flash shadows. Therefore, in the case does not affect the composition, so that people as far away from the white wall or behind objects, with sufficient space and distance, the shadow will be significantly reduced flash.

Choose a bright background

When shooting indoors, we can use natural light as the background under bright windows and doors can also use lamps and other lighting equipment available for people to be taken to create a bright background, choose the right camera angle, so that the shadow of the flash will disappear in a bright background.

The location of the camera to be higher

When using the flash indoors, the camera position is higher,ACER Aspire 5732Z laptop battery are some, such a flash behind the projector is in the figure below, will be part of the subject were blocked, it seems less obvious, minimize the use of head-up or looking up the machine digital photography. In addition, to avoid the composition vertically, as when shooting vertically, rotate 90 degrees to the camera, the flash in the side position, make it easier for some people fall on the side of the flash shadow in the background and characters on the left side of a contour line The thick black shadows. Banner in the photo shoot, the flash light source is above the issue from the lens, the projector weaker more.

Properly cover the flash

As small interior space, shooting from close, the use of flash is not only easy to cast a shadow on the face but also make the characters white, then, we can use the white gauze, paper towel stockings and even the role of the occluder with astigmatism proper shelter flash, the flash light becomes softer. Use of gauze and other items will be pasted with adhesive tape out of the flash (be careful not to block the hole and focus the viewfinder), a layer of soft, if not satisfied, you can add two or even three. However, cover the flash, the flash illumination will be reduced, thus increasing exposure to the appropriate value.

Use slow sync flash mode

Indoor use of flash photography, in addition to the flash of light, there will be injected into the natural light from windows and doors interior lighting, only because the latter two sources is weak,price of TOSHIBA PA3399U-1BAS battery can not let the main characters have enough exposure. We can use the slow sync flash mode, use flash light to illuminate the main characters, and then use a long shutter (1 / 15 ~ 1 sec) the other still life shooting indoors, you can use indoors to weaken the original flash of light leaving under the shadow. Best to use a tripod when shooting can also be fixed using tables and chairs and other objects, digital cameras, to prevent vibration when shooting while people were taken to maintain the original position after the flash lit until the shutter is closed.

Lighting method using reflection

You can adjust the direction of the flash or external flash can be used (installed on-top) of the digital camera, the flash head towards the people or the side opposite the ceiling, walls and other white reflective material, the use of a reflected light illuminates the subject person . This reflected light can change the direction of the flash, from the top of the front light or light into the former before the side light, and similar natural and soft light scattering. When this method to avoid the use of the colored surface, because its reflected light will cast a special color photo. To add flash from the camera as much as possible on top of a higher position, the reason for this is to make the strobe lights similar to the subject’s point of view angle of the sun, so that the shadows behind the subject naturally falls, and the shadow will not be annoying. This method is also impairment of light, of course, need to pay attention to the accuracy of the exposure.Dell Inspiron 9400 Replacement battery
 
When shooting portraits, no matter what the use of light, as long as the person in front of the subject and have enough brightness, will be reflected on to the eyes, appear reflective points of light to form eyes. Reflection points shown in the eyes, in shape, size and location is always different. For example: the indoor portraits, the light from those far away from the subject shining through the window, his eyes each window will appear bright shadow; use flash on the camera, it will cause in the eyes of a small central white point; the use of reflectors or reflective umbrella, it will form a reflection area, this reflex is usually to one side.

Not long ago, Mike, take a notebook to a friend’s house to play, a friend’s house using a wireless network, so Mike will connect the notebook to his wireless network Internet. Can be home, Mike has found in your own home with this laptop can not connect to home wireless network. This is why?
Mike was soon ruled out the possibility of hardware failure can not access the Internet, home desktop function normal Internet access through a wireless router, it appears that the network service provider should be no problem. That in the end is what causes can not access it? After careful analysis, Mike found that this failure is the SSID (wireless network ID) forget to restore the lead.Compaq NX9010 battery For example, we go to other wireless networks in the Internet with a laptop, the SSID must be modified to the wireless network SSID name in that environment before. After use, but also to change the name back, in order to use the original wireless network environment.
Here we give a concrete example, the D-Link DI-624 + router, for example, the default factory settings of the wireless network ID (SSID) for the “default” (see photo), the first use, if you do not modify The notebook computer will automatically search for wireless network signal “default” and connect automatically.
However, if you are on the router for wireless network ID changes, such as changed to “the wireless”, then there will be not normally connected to the network.HP G65 battery Then you can click Wireless Network Connection icon, and then under Network Tasks, click “View Available Wireless Networks”. Then the left side, under Related Tasks, click Change the order of preferred networks “. Click a wireless network, and then click “Move Up” or “Move Down” to change the order of the wireless network connection. Change is complete, you will find that the Internet can be normal. Therefore, in the wireless environment If you forget to change the wireless network ID (SSID) back to their logo, then, it will be unable to connect to the wireless network failure.
Small knowledge: What is the SSID? SSID (Service Set Identifier), can also be written as ESSID, wireless AP or wireless router is a sign of character, sometimes translated as “the business group identifier, the service set identifier” or “service area identifier”.Compaq TC4200 battery The flag is mainly used to distinguish between different wireless networks, up to 32 characters. The factory default value is “default”.

So after-sales, Konica Minolta and I am

So after-sales, Konica Minolta and I am
I was a company computer maintenance personnel, due to the company’s business has developed rapidly, computer office applications requirements increase as the original use of inkjet printers has been a bit powerless, so in the end of 2004, purchased a Konica Minolta up to a laser printer, model 2300W. See this color laser printer of the leaflets described above, the performance is also decent, the price of 4000 yuan at that time regarded as relatively cheap, and businesses to introduce this color laser printer to use, relatively inexpensive supplies. Used for the first failure
Initial installation of the printer is of course the dealer is responsible for the staff two or three erupted put the accessories are installed. Although it is a color laser printer,Toshiba PA3465U-1BRS replacement battery but Konica Minolta 2300W does not look stylish, square. Machine itself was equipped with a parallel port print line staff with a USB print line over, saying that the use of time in case of need. I feel USB cable “advanced” point and supports plug and play, so I believe the staff put on a USB print line. Then is to install the driver, the machine comes with CD-ROM into the CD-ROM drive, jumped out to an interface, suggesting that the press “OK” to install, the installation process without prompting what to pay special settings, there is no error, very well to complete the installation, print a test page to show me a very clear, but goes on the test page waiting for a long time to come out.
Company’s equipment is the sharing of resources, so I share a printer on the network, colleagues heard the new printer is fast and clear print, we are using this machine to print. Who knows after a few hours, the printer will not work, the print queue which came in several files waiting to print, the top of the file seems “stuck”,HP G65 battery the status bar error, the window of the driver itself with monitoring turns red, and a message to say “Please check your power supply or computer cable is connected properly, restart the computer, they can continue to use normal green tips. With a few days, found that this problem will always appear, sometimes several times a day, sometimes there will be continuous printing dozens of pages of information. Can not stand, so I called the dealer service personnel over the repair, he checked the machine, said machine no problem, so I changed to a USB print cable, said cable. I hold the dubious mood was observed for several days, found that the situation does not improve. So I contact that dealer response is that you try again or we ask the engineers, and then let the matter rest. For technical support to understand why
Is not the case, I think that Konica Minolta has a 800 toll-free consulting, so try to call the past to ask. I put that machine them out, and the technical staff some advice to me, which I think more constructive to my USB cord into the parallel port print line. I USB cable replaced with a parallel port print line as he said, with a few days and found that the situation has improved, probably the problem the number of times less than before by about half.
Konica Minolta 2300W interface such a situation continues for several months in 2005 when the company needs to buy a color laser printer, the leadership taking into account cost, to buy a Konica Minolta 2300W Color Jida. With a period of time to buy a new printer the same situation. So I call again to Konica Minolta’s help, this phone is a technical staff, I re-tell him again. This time the technical staff is very straightforward, 2300W This printer does have this problem, this model is not suitable for network print sharing, described in the readme file of the driver, this model memory little, if more, then print the file may appear out of memory, and printer disconnection if users need to share a printer,Compaq NX9010 battery buy a model with network printing capabilities “. This said very clearly, but I am puzzled, two or three hundred dollars inkjet printer can support print sharing, print sharing printer is one of the most basic functions, spent 4000 yuan purchase of color laser printer actually can not support shared printing. The key is in the purchase of the former dealer did not say any hints, packaging machine does not support shared printing.
Shameful after-sales service, then I played several phone calls to Konica Minolta asked several different people to answer almost all, say that this model does not support shared printing. I asked is there a way to solve the problem of shared print, they said no way. I asked you such defects should inform consumers. They say there is a readme file in the driver installed, which referred to do not support shared printing. So I carefully read the readme file that text files are in English, but fortunately my English level is not bad, my entire read, did not see such a word. Even if this sentence, also just purchased a printer installed on the driver can see, this is not to deceive consumers? Later anti repeatedly hit the end of the phone in the past many times the roots of the purpose is to solve the problem, may Konica Minolta 800 telephone operator heard come to my voice, and said less than two words, simply hang up my phone. I found online Konica Minolta’s China headquarters in Tel Surprisingly, found on the Internet, or 800 calls, so I call back, trying to find the responsible person or department heads, but the operator gave me the reply is: “our side there is no competent manager is not responsible for the after-sale thing.battery for Toshiba PA3465U-1BRS battery
” This really did not hope, do not reply to such a large company, to the customer is so irresponsible, a “no way” the matter?

These products are not suitable for most users, they are often only for specific user groups. As a business, be obliged to inform the consumer of the product characteristics, and the maximum to avoid consumers make the wrong choice. From Konica Minolta color laser printer events, Konica Minolta, and not in the product packaging, brochures and prominently marked products for network print sharing, or other precautions, and the driver readme file tend not to ordinary users of concern, not to mention English. Plus dealer bent on increased sales, not for the users to consider, and ultimately cause consumers to make the wrong choice.
Belden pretend a user dials 800, Konica Minolta, ask 2300W support network shared printer? Consumers before buying how can we know it does not support shared printing? If you buy after the discovery of how to do? In addition to clearly tell the 100 through 2300W does not support shared printing, and other issues did not get a better answer. As a disadvantaged group, the consumer has the right to know the characteristics of the product before purchase products to make it clear that the PC and other peripherals sold within 15 days, consumers have the right to a replacement computer Three Guarantees. Estimated that the author Fred is not within the specified time the timely processing of the problem, delay in time to make their rights lost hope that readers encountered a similar problem of attention should be given rights!
