Speaking of what a flash, the general photographers jvc gr-hd1 charger often have a misconception that the flash light source is used in low light the dark of the occasion, such as night, indoor and so on. In fact, Flash is a very useful auxiliary lighting, good use of a good flash light photography can greatly enrich the language, get a multiplier effect. For example, in people under sunny with a backlit scene, the characters or side light, fill light is often the method can be used to reduce light ratio and contrast. There are two ways to fill light, one is to use reflectors for fill light on the main characters, but more trouble, carry reflectors nor the most convenient alternative is to use the flash on people or close advisers fill light, it is more the ideal choice. Easy to carry because of the flash, color temperature and its color temperature close to the sun, both to improve the tone picture, but also to obtain more satisfactory color effects. Here to ISO100/21 ° film as an example of ways to use flash fill light. First metering (or estimate) the sun exposure combination of background, such as f/11, 1 / 60 seconds, then loaded on a flash, and flash the flash power index (assumed to be 16) divided by the predetermined aperture factor or 16 (index) ÷ 16 (aperture) = 1 (m). At this time in the 1m people at the subject with a flash, the jvc gr-dv3 charger exposure just right. This is just a direct shot, very bright flash and the sun, the sun backlighting may dilute the effect and cause the direction of the unity of light. The correct way is to let people around 1.5m away from the camera, so that the effect of relatively weaker flash, backlighting can achieve both effects, there are dark-level best results, sometimes because the composition of the needs of people want to come nearer, the characters a little bigger, you can cast a flash on the white handkerchief in one or two (depending on distances and fill light intensity may be), weakens the flash of light to fill the role of closer. To use the fill light attention to the question: in general the usual center of the shutter the camera viewfinder, the shutter speed set too high some will not have a negative impact on the flash; but but-lens reflex cameras, the shutter speed is not flash sync speed than the specified otherwise, fill light may produce uneven situation. Flash exposure is mainly from the flash index, shooting distance and aperture decisions. Flash not only suitable for use in low light, dark, light can also be used as a variety of other auxiliary lighting. Auto flash easy to use, fast, but also should pay attention to some practical skills. In order to avoid the formation of a positive flash "red eye" effect, some of the camera flash mode also has a reduced "red eye" feature.
