Kodak DCS Pro SLR/n manual Exposure compensation, Exposure control, Number, Flexible Program

Exposure compensation	Exposure compensation for available light is activated by changing the
	shutter speed and/or lens aperture. Use the AE-L/AF-L (Auto
	Exposure/Autofocus Lock) button, the Exposure Compensation button, or
	Auto Exposure Bracketing.
	In flash photography with a NIKON-dedicated TTL Speedlight, exposure
	compensation can also be performed by varying the amount of flash output.
	Camera-originated exposure compensation affects both the foreground
	subject and the background; variations in flash output amount affect only
	the foreground.
Exposure control	Programmed Auto: Camera sets both shutter speed and aperture for
	correct exposure.
	Shutter-Priority Auto: User selects shutter speed and camera sets
	matching lens aperture for correct exposure.
	Aperture-Priority Auto: User selects aperture and camera sets matching
	shutter speed for correct exposure.
	Manual: You select both shutter speed and aperture, following or ignoring
	the meter’s recommendations to achieve the desired exposure.
f-number	The numbers on the lens aperture ring and in the camera’s LCD that
	indicate the relative size of the lens aperture opening. The f-number series
	is a geometric progression based on changes in the size of the lens
	aperture, as it is opened and closed. As the scale rises, each number is
	multiplied by a factor of 1.4. The standard numbers for calibration are 1.0,
	1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32, etc., and each change results in a
	doubling or halving of the amount of light transmitted by the lens.
Flexible Program	Flexible Program temporarily shifts an automatically selected shutter
	speed/aperture combination while maintaining correct exposure. That is, a
	desired shutter speed or aperture can be selected in Programmed Auto
	exposure mode.
Focus-Priority for autofocus	The shutter cannot be released until the subject is in focus.
	Focus-Priority is given to Single Servo AF mode while Release-Priority is
	given to Continuous Servo AF.
Focus Tracking	Enables the camera to analyze the speed of the moving subject according to
	the focus data detected, and to obtain correct focus by anticipating the
	subject’s position—and driving the lens to that position—at the exact
	moment of exposure.
