Famous quotes containing the words magic and/or number:
“The magic of photography is metaphysical. What you see in the photograph isn’t what you saw at the time. The real skill of photography is organised visual lying.”
—Terence Donovan (b. 1936)
“I can’t quite define my aversion to asking questions of strangers. From snatches of family battles which I have heard drifting up from railway stations and street corners, I gather that there are a great many men who share my dislike for it, as well as an equal number of women who ... believe it to be the solution to most of this world’s problems.”
—Robert Benchley (1889–1945)
