Today we talk about the use of flash light digital photography CANON bp-535 Charger skills, luminous intensity in one hundred joule below small electronic flash, as an independent unit of light, easy to carry, no matter in the indoor or outdoor, can be taken as a photography as photos of assistant.
On the market at present is the sale of small deft type, form tiny flash, various category, and have many different function to choose from, some still have spread, the light of can become soft, lamp holder may make some different a change of canon powershot sd700 is charger direction. "Hot boots" equipment, can be directly inserted in a camera on top, don't have to, but said the wiring is very convenient.
The flash placed in the camera at the top, light ray with the direction of the camera lens, shooting direction ahead characters, got the "is the former light" (also called PingGuang) effect. If took were positive, facial won't appear as characters, so like, shadow side also no nose shadow, only the four points in three sides or quaver face, just like seven can meet with a little nose shadow appear. Generally speaking, whether positive or side, on the character contour, will appear around the contour line slightly darker, and the bright lights take is the former light like daylighting result is the same. Single light and the flash installed in camera canon powershot sd780 is charger, although not at the top of the characters in light shadow, cause before but it is easily make characters in the background projection projection, make appear black background projection, how much will affect the picture a concise and beautiful, to avoid the shadows of the dense, many ways, will move out of the top of the camera flash, to other position, can avoid will shadow intake in the picture.
Because flash has moved from the camera, to get with the shutter synchronous flash, must be connected to the wiring or long shutter, wiring length B generally no provisions, and can use two or three wiring connection to use each other. As long as one end of the connection of flash plug into the camera can be shot. As for the class B shutter, although need not connection wire, but certain limits. When opening the door, B away from the camera canon powershot sd800 is charger flash, the shutter before the close of play flash can lighting function. But because B door is any time, generally exposure time cast a long, so must in the darkness of the environment, use at night, use this method took characters. Sometimes several teams to use flash for the synchronous flash (with synchronous flash sensor), in order to achieve the daylighting of the perfect effect. To cooperate with the night scenery of the atmosphere, must be long exposure, was taken in the long time of characters exposure should maintain the stability of the body, otherwise there will still be moving images of the faults. In the process of exposure, whether to start a shiny flash, or in the process of exposure, shining effect is the same. Usually, shoot somebody at night, even if the character is already quite stable, but there is always a little moving, if flash continuous ablaze two or more times as the slight, will move image "frozen" down, make it image, therefore, mobile trace only a flash will have enough to performance, unless the effect of continuous motion is the character, for when again.
Digital photography on people's multiple images, is light flash to cope with things. For example the zoom lens, using different focal length, can get taken different sizes of character imaging, when zoom lens to use a long-focal-length, characters, with the flash first imaging larger one take, then will shorten the focal length of the lens, the imaging character some small, open bright will some flash for the second time, with different RuShiZhe flash the focal length of the filming the size of several different characters, on the picture is imaging can appear the same character of multiple images. Use this law, should be in the night, indoor or outdoor all can, using the canon powershot sd850 is charger deep black no reflective background, the effect will be more ideal. If in the flash and have the color before colour filter shooting, every time a kind of color can be taken, concentrate on a few different colors of the image can be made interesting characters, the picture. If no colour filter color, can use the color pt, and a good effect instead. If need to reflect the characters true colour, is in to take the last character image, will be covered in the flash of the former colour filter remove, using the white light to shoot one time, you will get the true colour character images.
Is also has repeatedly flash, if switch to motor volume, can control chip camera canon powershot sd880 is charger that in a second take two to three zhang, in night shoots, despite the action of make a different characters, through the motor volume slice and continuous flash, can record characters in a very short period of time for the action. But this method, not in the same negatives in different position, only the characters by case, is taken for the ointment. If in the same negatives record moments of continuous action figures, would want to be another additional a, can control several teams of shiny equipment for flash respectively to become.
