Scanning Color & B/W
High Quality Digital Scanning in colour, B/W, Grayscale Scanning upto 16mm Thickness (Length Unlimited ) Scanning width 42 Contex 42 Colour Scanner The scanning B&W (traditional silver) negatives, some people seem to prefer/recommend using RGB, rather than gray scale mode. Assuming a well calibrated scanner and a truly neutral (grey) negative (no purple tint and correct profile for the film base fog) shouldn’t all the colour channels record identical reading?
If the dynamic range of a given channel is above that of the other two, I can understand the possible advantage of scanning in RGB mode and using that channel as the grey value (in which case, the grey scale scanning mode should be able to do the same on its own (use the most sensitive channel, rather than averaging the 3 colour channels?)
