Slow Sync
A flash technique for using the flash at a slow shutter speed. Flash shooting in dim light or at night at a fast shutter speed often results in a flash-illuminated subject against a dark background.

Slow Sync - A special mode in digicams that opens the shutter for a longer than normal period and fires the flash just before it closes. Used for illuminating a foreground subject yet allowing a darker background to also be rendered.

Try Slow Sync Flash
Another limitation with in built flash units is that they can produce quite harsh results that mean any other ambient light in a scene is lost.

Slow sync isn't selectable separately on these Canons. Program mode always uses a faster speed of about 1/60 as its lower limit. Tv, Av or M modes use slow sync by default. See p.92 of Canon's 20D manual for details.

Slow Sync
Also called Night Scene or Night Portrait, it opens the shutter longer than normal, then fires the flash, thus lighting the foreground by flash but also correctly exposing the background.

Slow synchronization - is used in night photography when you want to activate the flash and maintain the low shutter speed in order to expose the background.

Sometimes slow sync is a desirable effect, since it can add a sense of dynamic motion to a photo. However, it can also tend to look like a blurry mess. If you want to freeze motion with your flash unit you should set a faster shutter speed.

While some cameras default to a 1/60th or higher shutter speed, others allow you to set a slower shutter speed (often called "slow sync").

soft box - a diffuser built around the bulb of a photographic lamp, used to soften the light.

That's why you're familiar with the other flash modes available on most mid-level and higher point-and-shoots: fill flash (or flash on), night scene (or slow sync flash), flash cancel (or flash off).

However, unlike with Auto and P modes, the flash ratio never increases beyond about 1:1 and exposures are as long as necessary (aka "slow sync").

Shutter speeds range from 30-1/2000 second. A pop-up flash can capture first and second curtain flash, slow sync flash and other standard flash settings. The aluminum and magnesium body is more rugged than most compact cameras.

Slow synch or fill-in mode is the most versatile. The camera will choose a shutter speed for the ambient light plus a small dose of flash to lighten the foreground.
