Save the Color Image. Color Balance Your Monitor Test the color balance of your monitor by giving the name of one image for all three colors. The screen display should appear in shades of neutral gray. If the image has a green, blue, magenta, or other color cast, adjust the color balance of the monitor so that you see neutral gray image. If these controls are internal, have a technician adjust the monitor for you.
Most monitors distort the brightness that they display, with the middle values appearing too dark.
For most monitors, a monitor gamma value of 1.9 does an excellent job. Although tricolor imaging is simple in theory, it is difficult to put into practice. For realistic results, you must use a filter set that closely approximates the spectral response of the display phosphors on your computer monitor and the tricolor sensors in the human eye. Because the Edmund filters transmit more light than the Wratten filters, exposure times are considerably shorter with Edmund dichroics than with Wratten filters. However, the high infrared sensitivity of the TC245 CCD chip means that neither Edmund nor Wratten filters cannot be used by themselves make accurate color images .
