Convert to black and white
You can convert edited photos to black and white image with Automata. Black and white conversion is the final of Automata's processing steps. Black and white conversion keep edited photos as RGB (8 bits/channel). Suppose you want to save a converted picture as an 8bit image. You need to use Convert to profile tool with a suitable grayscale ICC-profile.
You can tune black and white conversion by adjusting RGB channel coefficient values. To get the best result, the sum of RGB channel percentage values should be 100%.
