DC Flash usage guidelines

Basic level digital cameras generally have three Flash mode, auto Flash, red-eye and close Flash. Then the high point of the product also provides a "Flash" or even "slow Flash" function. So, their difference? when you use the actual filming what Essentials? automatic Flash normally, point and click (using film) and digital camera in the middle and a digital camera usually have three Flash mode, auto Flash, red-eye and close Flash. Then the high point of the product also provides a "Flash" or even "slow Flash" function. So, their difference? when you use the actual filming what points?

Auto Flash

Typically, point and click (using film) and digital camera without any setting changes that Flash modes are preset in the "auto Flash" mode.

At this point, the camera will automatically determine whether the shooting scene lighting. If not, it will automatically open the Flash movie to Flash, to compensate for the light. Most of our Flash shooting, "automatic" mode is sufficient.

Eliminate red eye

"Red eye" phenomenon in photography portrait photos (especially near distance, the environment is dark) often occur.

This is because the eye retina reflex Flash. If you do not want to shoot out of a person or animal eyes appear "red eye", you can use a digital camera "red-eye" mode let Flash Quick Flash once or several times, the pupil to adapt, before the main Flash and shoot.

Turn off the Flash (Flash not mandatory)

As the name implies, is forced to shut down Flash digital camera.

Whether shooting environment light conditions, no Flash. This feature is most appropriate to prohibit the use of Flash where to shoot. If the author has used this feature in the filmed in Mt. Emei Temple in the forbidden city gold Buddha, "Dragon Ball" shots. In addition, with this feature in the evening or low light environment will be better able to create a natural atmosphere of the film.

-Flash

Also is to "turn off the Flash" on the contrary, that is, whether it is bright or low light environment, open the Flash for Flash.

Usually in the back of the light source to shoot. Because shooting people, if the principal is backlit locations (such as shooting a light dark characters in housing, the principal with his back to the bright window), the main façade is in the shadows not clear. At this point you can use this feature in Flash's effective coverage photographed subject light uniform photos.

Slow sync Flash

In the light dark environment when taking photographs, if you use Flash plus a higher shutter speed shooting, it is easy to cause Outlook body too bright, or even white Akira Akira's piece, and the background is still gloomy, unable to distinguish details.

The "slow flash synchronization" will delay the release of the shutter for digital camera to Flash illumination prospects, combined with a slow shutter speed (1/5 of a second) and low light background exposure. In this way, you can take out front and King were photographs of harmonious exposure. My own experience is in the rain and fog days of Huangshan filming "Welcoming pine". However, using this function has two considerations, first and foremost to shoot low light environment, using slow shutter shooting may be because the hands of blur caused by jitter photos. I suggest that you use the camera dedicated tripod support digital cameras to remain stable. Second, when using the Flash accessibility, attention to shoot shooting distance should be the effective coverage of the Flash. Medium range digital camera with built-in Flash coverage limited to photography enthusiasts, the lower the Flash index (generally 1 ~ 9 m), but has basic meet normal shooting.
