Because the correct flash mode varies depending on your subject, lighting, and the
type of photography you want to do— Here’s a mini review of commonly available modes and their uses:
• Auto flash Triggers the flash when the camera thinks it’s needed, which is a great
feature for casual snap shooting.
• Fill (or Force) flash Fires the flash for every shot. You often need to use this
mode for good outdoor portraits.
• No flash Prevents the flash from firing, which is a good thing when you’re trying
to shoot shiny objects, such as glass or chrome.
• Red-eye flash Produces a mini flash that lights in advance of the main flash. The
idea is that a subject’s pupils will constrict in response to the mini flash, thereby
lessening the chance of red-eye, which is caused by the main flash reflecting in said
pupils. In a dark room, the feature rarely solves the problem entirely—which is
why manufacturers refer to this feature as red-eye reduction mode, not red-eye
prevention mode.
• Slow-sync flash Enables you to use slower shutter speeds than the camera
normally allows for flash photography. When you’re shooting at night or in a
dimly lit room, this mode enables you to capture both subject and background.
Without it, the background usually appears dark.
If you’re working with an accessory flash unit instead of a built-in flash, you may
not be able to take advantage of the full range of flash modes on your camera; check
the camera and flash manual to determine your options. You may also find that you
can adjust the intensity of both the on-board flash and the external flash unit by using
a Flash EV control.
