When should I use a flash when shooting with a camera?

When shooting with a camera, you should use a flash when the light in the shooting scene is insufficient.

As the main tool of supplementary light and night lighting, the light quality of flash lamp is much harder than that of natural light. However, as long as it is used properly, from airborne low-power direct flash to professional external flash, it can create a unique shooting effect for dark subjects.

When the ambient light is dark to a certain extent, even if the camera is adjusted to a higher ISO and maximum aperture, it will sometimes face a very low shutter speed. At this shutter speed, it will become quite difficult to shoot by hand. At this time, even if the automatic mode of the digital camera does not force the flash to be turned on, in order to shoot more clearly, it is necessary to manually turn on the flash to make necessary light supplement.

Guide to the use of digital camera flash;

1. Auto Flash: Usually, when the camera (using film) and digital camera do not make any setting changes, the flash mode is preset as "Auto Flash" mode. At this point, the camera will automatically determine whether the light of the shooting scene is sufficient. If it is insufficient, it will automatically turn on the flash when shooting to make up for the lack of light.

2. Eliminate red eye: When taking portrait photos (especially in close range and dark environment), "red eye" often occurs. This is caused by the flash reflected from the retina of the eye. Using the "red-eye-eliminating" mode of digital camera, let the flash flash once or several times to make people's pupils adapt, and then take the main flash and shoot.

3. Slow synchronous flash: When taking pictures in dim light, if you use flash and high shutter speed, it is easy to cause the foreground subject to be too bright and the background to be gloomy. "Slow flash synchronization" will delay the release speed of digital camera shutter, use flash to illuminate the foreground, and cooperate with slow shutter to expose the weak light background. In this way, you can take photos with harmonious exposure before and after.

People's Network-The clever use of slow synchronization of airborne flash is equally wonderful.
