I am working on an old B&W image that has been converted to digital and I want to add another character that was video taped on green sceen. My question is that since that final version will all be in B&W is it better to import the image (green screen) in color and then desaturate the color in my editing software? I am thinking that if I lose the color information before when I import in Chromanator it will not have any green to read from. Is this right. Any help would be appreciated.
