Speedlight tips.

Middle and low current digital cameras usually have four flash modes, auto flash (low light and backlight conditions in auto flash), remove red eye function (low light and backlight conditions in automatic flash and turn off the flash), Anytime Flash (all .take all flash) and forced non-flash (not flash all the shooting), some digital cameras even have a slow sync flash <p> <u> middle and low current digital camera </ u> usually have four flash modes, namely, .Auto flash (low light and backlight conditions in auto flash), remove red eye function (low light and backlight conditions in automatic flash and turn off the flash), Anytime Flash (all shooting is flash) and forced non-flash (all shooting no flash) .Some digital cameras even have a slow sync flash. .Then these functions model different? .What are the main points of the actual shooting and the related application skills? .</ P> <p> finished shooting was able to see digital photography over traditional film cameras convenient place, but to the performance of CCD digital camera is rather limited range of brightness. .In the ambient light shooting scene contrasts (such as backlit portraits), whether applied to expose for the bright or dark against light, always lose some image detail. .If you use flash fill light on your subject properly, the screen contrast will be greatly weakened, and shoot photos of the details will be clear. .</ P> <p> shooting in the general environment, the flash illuminates the scene the main role is to enable the camera to obtain the correct exposure. .At present, most digital cameras with automatic flash options, especially fool digital camera, without any setting will default to automatic flash mode, shooting will automatically determine the shooting scene when the light is sufficient. .If the dark shooting environment, a digital camera will automatically turn the flash on the flash to compensate for the lack of light to shoot out the light uniform image (Figure 1). .</ P> <p align="center"> Figure 1 </ p> <p align="center"> <p> </ p> <p> </ p> <p> </ p> <p> .</ p> <p> clear sky conditions in the snow taken a great contrast, the general approach taken will often become snow white no texture. .The reason is that digital cameras and traditional cameras, "Program AE", as 18% of the average values are in light gray color, and in the ambient light outside of this value can not be properly expressed. .While digital cameras can automatically adjust the brightness, but the digital camera as the human eye so keen, when shooting more snow and other white object, the digital camera will be wrong to judge the "light is too strong", and automatically capture the tone .darker picture. .In view of this, combined with the appropriate flash fill light will be able to shoot good white snow texture (Figure 2). .</ P> <p> under the ice in the cloudy film, if the picture is bright and most of the snow, the scene brightness contrast will be even stronger if the direct use of fully automatic shooting mode, the picture will appear relatively dark. .As the sun's reflection on snow, the characters face will be a strong backlighting effects, then must be forced to use flash photography, to be able to take to clear the characters facial details. .Experienced photographers can also use the camera flash exposure compensation function and assisted shooting, such as prominent figures would be easier to take pictures and rich facial expressions. .</ P> <p align="center"> Figure 2 </ p> <p> shooting flash is convenient, but sometimes the effect is not good to use, mainly because of strong and limited flash. .If the shooting distance is too far will cause the flash is inadequate; shooting can sometimes be too close to the case of the flash too strong. .It should be noted that the distance mentioned here is the flash and the subject is the distance between the camera and the subject rather than the distance between objects. .To improve the shooting, often need to control the intensity of the flash, and many digital cameras have flash compensation feature or function can be set to flash strength, flexibility of these features make shooting more comfortable. .</ P> <p> </ p> <p> </ p> </ p>.
