RE: filmscanners:What is Analog Gain



In case it might be of interest, here's the text from my LS-30 Nikonscan manual 
(pdf file):

 Analog gain is used to adjust the intensity of the scanners light
 source, emphasizing selected colors in the input image. The
 controls for analog gain consist of four sliders: a master slider
 that allows the user to increase the brightness of all LEDs in the
 scanners light source simultaneously, and red, green, and blue
 sliders that allow independent adjustment of the red, green, and
 blue LEDs.
 Moving a slider to the right increases the intensity of the affected
 LED; moving it to the left decreases the intensity. Click 
 the Help button for information on using analog gain.
 Note: Setting the intensity of the scanners light source too high
 may produce smear or other defects in the scanned image.
