Kodak DCS Pro SLR/n Matrix Metering system, Rear-Curtain Sync, Release-Priority for, Autofocus

Matrix Metering system	An advanced exposure metering system using a multi-segment sensor and
	computer.
Rear-Curtain Sync	Flash fires an instant before the second (rear) curtain of the focal plane
	shutter begins to move. When slow shutter speeds are used, this feature can
	create a blur effect from the ambient light, i.e., a flowing-light pattern
	following a moving subject with subject movement frozen at the end of the
	light flow. See also “Front-Curtain Sync.”
Release-Priority for	Shutter can be released anytime (i.e., even when subject is not in focus).
autofocus	Helps you avoid missed opportunities when you are not concerned with
	absolute focusing precision.
Single Servo AF	Once the subject is in focus, focus is locked. Useful for recomposing the
	picture.
	Release-Priority is given to Continuous Servo AF mode while Focus-Priority
	is given to Single Servo AF. Using Custom Setting, however, you can change
	the priority to Focus-Priority Continuous Servo AF or Release-Priority Single
	Servo AF.
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. Using a slower shutter
	speed with the flash brings out the background details in the picture. Use of
	a slow shutter speed with Rear-Curtain Sync is particularly effective for
	illustrating the movement of a stream of light.
	Slow Sync mode extends the automatically controlled shutter speed range
	(in Programmed Auto and Aperture-Priority Auto) down to 30 seconds.
Vignetting	Progressively diminished illumination on the image from the center to the
	corners. There are two kinds of vignetting—natural vignetting caused by
	the lens, and vignetting that is caused by improper use of accessories such
	as a lens hood or filter.
White balance	Provides adjustments to match the type of lighting used to capture an image.
