NAME
       dunncolor - set exposure	values for a Dunn Model	631 camera

SYNOPSIS
       dunncolor [-p] baseval redval greenval blueval

DESCRIPTION
       Dunncolor sets the exposure values in the Dunn Instruments Model	631
       camera to the specified values. If the -p flag is used, the Polaroid
       (8X10) exposure values are set. Otherwise, the auxiliary	camera
       exposure	values are set.	 baseval, redval, greenval, and	blueval, are
       values between 0	and 255	used to	calculate the exposure times for the
       red, green, and blue filters. The final value for each color is the
       product of baseval and the value	for that color (redval,	greenval, or
       blueval). Exposure timing is based on the counting of vertical SYNC
       pulses. The final exposure value	indicates the number of	SYNC pulses
       for which the camera's monitor should be	unblanked. At a	60 Hz rate,
       this means an exposure time of 1	second for every 60 SYNC pulses.
       Dunncolor reads the old values from the camera and prints them before
       setting the new values. The new values are then read from the camera
       and printed to verify that they have been changed. The five values
       printed are the exposure	values for base, red, green, blue and
       black/white.
