Translate black and white effect from English to French

– One of a group of photo modifications someone can make to a color photo that mimic different effects that would be achieved by taking the same photo using black and white film stock. One effect uses strict conversion to monochrome by throwing away all of the color information. Others mimic the result when a black and white photo is taken through a colored filter—orange, red, or yellow—to enhance or suppress certain color information. Two effects perform strict conversions to monochrome and then apply a color tint—sepia or cyan—in one step. ¹
