I have a lot of black and white food photos—some are because Michael's book Ratio was printed in B&W, but there are times when food photos look better in B&W—as in this one of Michael kneading dough. The important information here is the texture of the dough and the flour on the cutting board. In the color photo there is little contrast between the colors, they are not important to the image nor do they compliment each other. Here, the black & white looks OK because there is a lot of texture and a full range of white to black tones, but the color—Wow. The purple compliments the green perfectly and the color becomes very important. The most important thing to know about converting your color digital files to B&W is you must adjust the contrast and exposure settings until you have a true black and a bright white. I almost always increase the contrast as well as adjust the tonal levels. Just pushing the convert to B&W button will leave you with a flat gray muddy photo. Blah.
