1, Ni-MH battery must be bought at just the time to put the battery canon np-e3 battery in the power net,to measure battery capacity Ni-MH battery is working normally takes 3 --- 5 times or so, the battery in the charged particles will be fully activated.
2, charging time must be strictly according to the instructions on the time control (not the so-called red 10 --- 24 hours), to tell you 8 hours to charge 8 hours (time control in the range of about 1 hour), beyond this range of particle properties of the battery will severely decline.
3, Ni-MH battery canon digital ixus 750 battery in fact a memory, the best charge every time fasting.
4, if you once bought a four batteries, and the first use of two cameras must be grouped (for example: 1 and 2 with / 3 and 4 together), to avoid charge different capacity of batteries together.
5, different power and different capacity rechargeable battery can not be put together.
6, different brands of batteries and chargers so as not to be used together.
7, the battery can not bump or fall on the ground this would decrease the battery performance.
8, the battery can not metal objects together (key) in order to avoid short circuit.
9, long time not to be placed on the battery canon powershot sd990 is battery is fully charged, the next use of the time in the full can.
10, when used in winter as much as possible the number of spare batteries you use the camera more than 3 times in order to prevent because of the weather, the canon battery power is low (recommended temperature of -17 degrees).

Tips for shooting fireworks
Tips for shooting fireworks
New Year's Eve fireworks CANON PowerShot SD600 Charger I took some photos and upload to the "Photographers'Companion" get "Spring Photography Contest", received attention of many friends, and asked how to shoot. I then shared four tips for shooting, and now I put them into a post, so that more people shared. Although the film has passed the peak of fireworks, but the skills of knowledge is, but when!
First, the location shooting
Shooting CANON PowerShot SD630 Charger fireworks can also be regarded as a kind of landscape photography, and filming the most important landscape composition, on location choice is the key to composition. Shooting fireworks to try to choose a higher place, is the so-called "stand high and see far ahead!", Seat selection can be high not only panoramic view of fireworks, and can make some of the buildings as the foreground or background to make the screen more substantial and colorful .
If you can not find the height of the location, then you should try to use some light to fill vacancies in your screen, for example, track lights!
But no matter what the location Ye Hao, shooting fireworks are always less people and more places, with Friends of the impact of like-minded people out there, most often the location for several hours before the start of the tripod have been packed with faithful shadow . And people who watch a lot of people. Therefore, if you go to popular places to shoot the fireworks, there should be prepared to wait a long time, there are friends to the best shot, go away for a while have a friend take care.
Second, the equipment
The camera, basically the most entry DSLR and can also be a hedge. Standard zoom lens can capture wide-angle environment, the composition can also be tightened at any time, shooting fireworks or some buildings close-up, fixed-point shooting can be a little change.
The most important tripod shooting fireworks! ! ! Sufficiently high enough to have a solid tripod is a must. To stabilize the camera work is solid, while the high from being the scene of the fence or other debris shielding of the composition. In addition, the use of cable release to be able to avoid camera shake caused by the shutter, more convenient when shooting fireworks.
Third, the shooting techniques
Fireworks photo shoot, the protagonist not only fireworks, but also the background or foreground. Therefore, balancing the exposure, is the shooting point. Another limitation is the same shutter speed, the shutter will make fireworks track too short, too long exposure time will make the screen too many fireworks, and noise elimination and may increase the time, missed the next round of shooting fireworks opportunities.
I will use when shooting black smoke card practices, something the fireworks CANON Charger will be different times overlap in multiple exposure mode on the same photo, so that the screen is more abundant. But in the digital era we have to use the software for subsequent multiple exposure, coupled with the fireworks in recent years, most are very dense, has less exposure time can make the screen filled. I generally use the ISO100, aperture 22, shutter speed is generally between 25 seconds to 30 seconds to light intensity can be balanced to take care of the problem and the trajectory of fireworks. For the foreground or background overexposed, we can use the black card to block. The easiest way is to have a hand to block the overexposed, blocking a second or a few seconds to reduce exposure.
It should be noted that if the evening wind speed is not high, the fireworks can not be paid when the smoke blew away, the early release may only clearer, after the fireworks have been issued in the smoke. So if there is no wind, then we would take hold at the initial stage of recording time.
As for white balance, the color cast of the color of fireworks is no problem, the most important is the background or foreground color, but I usually use auto white balance.but when!CANON PowerShot SD750 Charger

How to handle the color balance DV camcorder
As JVC BN-V514U Charger technology advances, the development of the camcorder tends to size small, functional automation and price is reasonable, while the television camera has quietly entered the people's entertainment. Television camera into people's lives not only enrich people's entertainment, but also to pursue more artistic people ... ... People often talk about the color screen does not reddish to bluish, the appearance of the screen. In fact, the color balance is a television camera is one of the important technologies. Here, I want to take the Sony DCR-TRV27E camcorder, for example, on how to correctly handle the DV camcorder's color balance of a point to talk about their experience and understanding.
Color is one of the means shape the TV screen, it has a direct role in human vision, gives rise to emotional responses. Color screen, a direct impact on the quality of TV programs, how to correctly handle the color balance of the TV screen it is very important. Correctly handle the color balance of the TV screen has two meanings: the TV screen should be properly restored the natural color of the scene, no color cast; from a deeper level point of view, the color television picture and television should be to convey emotion and mood is consistent. In this article, because of space limitations only talk about the first point.jvc gz-mg37u charger
"DV" is the "Digital Video" acronym. DV video camera JVC GR-DVX4 Charger is the digital camcorder. According to the different features and price, DV camcorders with home video cameras and professional video cameras of the points. Home video cameras and professional video cameras compared to the color balance in the regulation of the screen when the camcorder does not have manual white balance function, such as DCR-TRV27E only 4 white balance mode Hold, Indoor, Outdoor and Auto, but also Some DV camcorders only one white balance mode Auto. For professional cameras, the color balance in the pre-shooting machine improperly can take advantage of post-production effects in the appropriate remedy. For weddings and other family tourism and entertainment video, it does not have these conditions, once the shooting, when there is no way to make up. This requires shooting to correctly handle the color balance.
Here's the DCR-TRV27E camcorder, for example, to talk about the correct handling of DV video camera color balance method. In the above-mentioned DCR-TRV27E camcorder white balance adjustment is usually only 4 ways: Hold, Indoor, Outdloor and Auto. Their usage is different.jvc gz-mg130 charger

Sony second-generation CMOS R & D success back light
Recently, according to Sony's sony np-bg1 battery latest news, they have confirmed that successfully developed the second generation of back-illuminated CMOS devices will be added in the next time a new digital camera products. However, this new device is still developed for small size, can only be installed in the consumer-level digital cameras.
Specifically, the first component of this new 17.7 million pixel contains this product, its most important feature of many pixels that can simultaneously convert the signal, so the timing of the signals of the sensor than it is now about 75% of savings time. Also in terms of processing speed is also 5 times faster than the current sensors, to 34.8Gbps. Video recording speed up to 120fps. sony np-f330 battery
Another new product specifications for the 1/2.3 inch, 12 million pixels, is for smart phones and small digital cameras, it's a pixel size of 1.55um.

Capture DV video editing and compression
Make jvc gr-dv800u charger a good film, you can put directly on the DV save, then went with the DV playback machine can also be collected to the computer, the edited record back to DV belt can also be collected to the computer where carved directly into DV AVI files Save up to CDR can also be compressed into MPG, VCD carved or SVCD, DVD saved. MPG is a lossy compression, no matter what format is compressed, the loss of quality there, but the engraved plate MPG or the most common way to save, I think the main is so for several reasons:
1, DV video jvc gr-d750u charger playback performance on the TV is far better than the performance on the CRT, although the CRT resolution is much higher, mainly because the design of television is to display dynamic images, so the brightness, color on both CRT-based display static than better, and the resolution of ordinary television show only 320 lines, then the DV up to 720 × 576 resolution do not need, whether it is the 352 × 288 or VCD SVCD to 480 × 576 is enough So even though there is loss of quality compressed into MPG, but can not see on TV is basically out. In the computer point of view, SVCD resolution is enough clear.
2, DV jvc gr-d396us charger is a problem with the save, after all, tapes, DV is also used with time is not long, but long before the adhesive tape recorder and the mold we have seen in estimates. The CDR disc blue plate, green plate is generally for 30 to 50 years, the gold disk can hold 100 claims, although the CD is also the possibility of mold, but after all much better.
3, the convenience of playing on the disc is strong, DV with DV machines have to move out, but only on television, is also worn on the head, rewind, very troublesome, and VCD, SVCD discs more convenient I do not have to say.
4, then considered a financial account, DV with a box of 25 30, CDR 1.5 a, as I in March to buy machines to now, has carved out about 45 SVCD, CDR cost is less than 70, if into DV tape, probably 30 or so, even with the LP model also 20, which is several hundred pieces ah. 1394 card and now the recorder is very cheap, and bought these two things can do also other purposes.
Acquisition
What to do Well, here is how to do it, and now the DV machines generally have two connected computer interface, one of which is connected serial port or USB port connected, this is generally used in still image capture (some with MPEG1 compressed DV capture via USB port MPEG1 format, but less effective), another is that we use to capture DV video 1394, and stands for IEEE1394, also known as FIRELINE (FireWire), SONY machine called I. LINK the machine is a 4-pin DV small port on the computer 1394 generally is a large 6-pin port.
The first step is to install the 1394 acquisition card (of course, no computer has 1394 this step.) The card inserted in your computer's PCI slot ( laptop to buy an external PC card 1394 card), then boot, WIN98SE, WIN2000, WINXP these operating systems can automatically find the 1394 device and automatically install the driver program. If you find the 1394 card does not work, please put the computer's motherboard drivers and patches installed together, and then try to change it not interrupt or change the conflicting device operating system. Must be made clear is that 1394 cards have different chips, not all 1394 cards are compatible with all motherboards, and generally done earlier because the TI chip, and motherboard compatibility is better, and VIA chips, cards and VIA motherboard, of course their is no problem, but in co-ordination with other board easily go wrong. If the methods are used or not working properly, that is not compatible with the motherboard and the 1394 card. So when buying 1394 card, and businesses that are not compatible with the card replacement or return.
1394 card installed in the device manager to see the 1394 device to work OK. 1394 is hot swappable, but I do not have the habit is the computer off, but DV is off then plug the line, mainly because I think the DV relatively delicate, the computer because it is a clumsy thing, casually toss.jvc gr-d350u charger

Water sports shooting skills
Splashing CANON PowerShot SD600 Charger waves, sunlight sparkling in the bright reflective clothing to generate the body of water activities are exciting intense dynamic body of photographic subject matter. In recent years, water sports is committed to the development of creative use of cameras to provide a number of shooting opportunities.
And the usual way around, moving the body photography CANON PowerShot SD630 Charger does not always need to use long lenses . Is actually fairly simple to use photographic equipment, film planning canoe, drive boats, race boats, sandbars sailing, surfing, jet washed the raft and sports activities, can produce eye-catching photos .
300 mm or longer lens is expensive, and large weight. At the same time, to get good results , long-lens camera in the use of need more accurate than short focus.
I found, in this case is the secret of using a short lens as close as possible subject. Sometimes. This means that to get into the cold water, on your knees shooting. And thus must also focus on prospects for a person who, leaving spectators and other athletes in the background, it is particularly useful.
If CANON PowerShot SD750 Charger a specific sport in a fixed runway, I am usually a good distance prior to the test, select some of the best pre-tune focus. Choose the length of several different lenses to achieve different effects. Remember, water sports to shoot good pictures is not always to use high-speed shutter, fuzzy little pictures can often convey a strong dynamic subject, and the whole site can not have a clear picture. However, to master the use of this technique have to find out how much blurring is just right, it is best to appreciate from the practical experience to master. This technique also depends on what you shoot is sports, the length of the lens focal length used, and dynamic camera angles and the size of the body. Shutter speed below 1 / 60 seconds, the result is difficult to predict, but it has an advantage that can capture beautiful pictures with special effects, these photos are almost like a oil paintings. When using a longer exposure, the camera is placed in a stable tripod, shooting pictures out of the water looks beautiful.
Another technique is to use 1 / 125 second or even faster pace, to follow the photography CANON PowerShot SD550 Charger . Taken this way out of the picture, the subject is quite clear, but the background will show the fuzzy stripes. To make fast flowing water Ning Zhu, usually transferred to at least make the shutter speed 1 / 500 sec.
Especially when using longer lenses when shooting fast moving objects, in order to accurately focus is very difficult. The problem can be a point on the subject focus or follow pre-focusing to resolve. The former technique is simple and suitable for different situations. The latter technique is more difficult to master, but also to constantly adjust the focus to the subject matter can be clear when approaching or leaving. If you use an ordinary spiral focusing lens, until you feel there is no master of this technology to conduct training.
If you are using a 200 mm lens focal length or longer, more technical training to be a. It should be noted is that if you are using a different manufacturer's lens, then there is the lens to focus the sub-clockwise. Some counter-clockwise focus, then we should make sure you use all the lenses are focusing in the same direction. Otherwise, the height of the movement, you can be able to focus the direction of confused, missed most valuable shooting time. Should have a sports photographer, the most important skill is the ability to anticipate the peak action. Cartier-Bresson called it a "decisive moment." Ability to identify this peak is taken by your campaign to be carried out thorough and careful observation and accumulated. I realized that, to sit down calmly, to be taken on the kind of idea photos carefully. Before shooting and the problems may be estimated to be crucial. This does not make you shoot some documentary photos. You can also draw a few sketches before shooting, you expect the effect to get some discretion, which is particularly useful work.
In my view, mental preparation and selection of at least as important as the appropriate photographic equipment. Mentally ready to not only help you capture the scene of the accident, but also allows you to overcome the harsh environment encountered difficulties. Even with or without boots and umbrellas on the success or failure has a great relationship. Sometimes carrying a camera, the camera is waterproof cover to prevent water splashing or immersion. Indeed. A professional photographer is best to buy a sturdy waterproof cover, if you do not often use, you can buy a very cheap made of polyethylene and flexible waterproof cover. I find that both durable and waterproof cover is not easy from the floor. On one occasion, shooting rapids in the Zambezi River red raft movement, my camera to escape calamity.
Now to talk about how to determine the correct exposure. Unfortunately, the automatic TTL exposure meter is easy to light reflected by the water shortage caused by the exposure. When transferred to the ideal position polarizer, the polarizing filter can reduce the reflected light in some nasty, but also increase the color saturation. In addition, you can use a handheld light meter to measure incident light readings taken, take back of the hand can measure the reflected light readings; press 1/2-2/3 file to increase exposure. If you use a polarizer, do not forget to increase the required exposure compensation. (Increase of 1 / 3 block) by manual adjustment TTL exposure meter measuring the reflected light readings taken back of the hand, you can also get the same effect. If your camera's CANON PowerShot SD500 Charger light meter can only be controlled, you can compare the hand and features readings, and then adjust the exposure properly. In this case, exposure compensation is no longer needed because the polarizer to the lens has already been installed on the.
And the usual way around, moving the body photography CANON PowerShot SD630 Charger does not always need to use long lenses .
