Automatic flash
Usually, the traditional flash film camera and digital camera do not make any setting changes, the flash mode is preset in the "auto flash" mode. At this point, the camera automatically determines whether there is enough light in the scene. If it is not enough, the flash is automatically turned on during shooting to make up for the light. In most of our shooting situations, the "auto flash" mode is sufficient.
Red eye
The English name of red-eye reduction is Redeye reduction, and the sign on a digital camera is generally an "eye." The "red-eye" phenomenon often occurs when taking portrait photos (especially close distances and dark environments). This is due to the flash of retinal reflection in the eye. If you do not want the eyes of the person or animal you are shooting to have “red-eyeâ€, you can use the “red-eye reduction†mode of the digital camera to flash the flash once or several times to adapt the pupil to the main flash. Shooting. The following are different pictures that can't be opened in both red-eye and red-eye mode.
Forced not flash
Forces the digital camera to turn off the flash. No flash is allowed regardless of the lighting conditions of the shooting environment. This feature is best suited for shooting where the flash is stationary.
Forced flash
Turn the flash on to fire in bright or low light conditions. It is usually used to photograph people who are facing back to the light source, which can enhance the brightness of the character, but it is easy to cause noise increase and overexposure.
Slow synchronization
Turn the flash on to fire in bright or low light conditions. It is usually used to photograph people who are facing back to the light source, which can enhance the brightness of the character, but it is easy to cause noise increase and overexposure. When photographing in a dimly lit environment, if you use a flash and shoot at a higher shutter speed, it is very easy to cause the foreground subject to be too bright, even a piece of white, and the background is still dark and cannot discern details. The "Slow Flash Sync" delays the release speed of the digital camera's shutter, exposing it to the foreground of the flash illumination, with a slow shutter (eg, 1/5 second) for low-light background exposure. In this way, it is possible to take photographs in which front and rear scenes are harmoniously exposed.
External flash
External flash can be divided into two types: one is a universal model that can be used for cameras from different manufacturers, and the other is a specific camera model. Since the flash built into the digital camera directly illuminates the subject with strong light, it sometimes produces unsightly shadows. It is best to use an external flash at this time. Recently, there are more and more digital cameras that can use external flash. If it is a model that can use an external flash, it would be a shame if not.
Front/rear curtain sync flash
In the case of low light, the shutter speed is slower, and the front/rear curtain sync flash basically does not increase the shutter speed. Such as normal metering, the maximum aperture, the shutter speed is 1 second. After turning on the first three flash modes, the shutter speed can be increased to 1/90 second. While the front-curtain sync flashes, it flashes for 1/90 second while the shutter is open, and then continues exposure for 1 second or 1/2 second. The rear curtain sync flash is the opposite of the front curtain sync flash, and the flash does not start until the shutter closes after the shutter is opened.
