Flash sync is refers to the canon lp-e5 battery flash right in the full open shutter the moment, make the whole picture ablaze even feel the flash. Use flash attention should be paid to control the shutter time, when the shutter speed higher than digital camera flash synchronization time, the shutter will in the picture some part of the body had yet to be shut down, leading to flash exposure picture black edge.
Not synchronous flash there are canon lp-e6 battery two main reasons: the shutter speed higher than the synchronization time DuoGe use flash, flash, flash time not the flash consistent.
Ordinary consumer digital camera canon powershot sd750 battery flash synchronization time at 1/400 SEC, when using flash within, if the shutter speed higher than digital camera flash synchronization time, can appear not synchronous flash the phenomenon, the picture will be black side or picture by light, even at this time reduce the shutter speed, make its displeasure in flash synchronization time can. Usually, use the built-in digital camera flash won't appear not synchronous flash the phenomenon, use the built-in flash digital photograph opportunity for automatic shutter speed, namely a cap on flash synchronization time, user can not be higher than the shutter speed accesses the speed, when use external flash, users need to pay attention to the shutter time, avoid flash sync.
When used at the same time DuoGe flash, if these flash is not also lit up, the picture of whole partial dark or appear may black edge. If this occurs, the user can use matching trigger led flash to ensure all the flash also received flash signal, and illuminate the foreground body.canon powershot sd30 battery

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

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.
