Confused about the colour gamut? Who would have guessed that one of the best explanations I’ve run across so far comes from a book (delivered this morning from Amazon.com) on black and white photography. Mastering Digital Black and White by Amadou Diallo is terrific. Although a bit dated (it was published in 2007 after all) the information about how to produce master class black and white prints (emphasis on Photoshop but most of the information pertains to other software as well) is very well explained although the author recommends a shot of whiskey every once in a while as we try to figure out what colour scheme to use when printing black and white photos. Huh! See what I mean? Diallo says you need to understand colour to print in black and white.
