Black and white photography is a perfect lie. We must not let colour destroy this image. - Patrick Summerfield - [cited in: Creative Camera April 1970, p. 118]
 
One very important difference between color and monochromatic photography is this: in black and white you suggest; in color you state. Much can be implied by suggestion, but statement demands certainty… absolute certainty. - Paul Outerbridge - [Julia Scully, “Seeing pictures”, Modern Photography, Oct. 1976, p. 8]
