There is nothing, under present conditions, that can be more easily and exactly reproduced than a technically good black-and-white photograph, and it is utter rot to burden those interested in them with irrelevant biographical trivia and pet longwinded theory. - Clarence John Laughlin
 
To speak technically photography is the art of writing with light. But if I want to think about it more philosophically, I can say that photography is the art of writing with time. When you capture an image you capture not only a piece of space, you also capture a piece of time. So you have this piece of specific time in your square or rectangle. In that sense I find that photography has more to do with time than with light. - Gerardo Suter - "Black & White Magazine for Collector of Fine Photography", February 2001, page: 118
