People believe pictures. It's a photograph that's in your passport, not a painting. Now, George Bernard Shaw said, 'I would exchange every painting of Christ for one snapshot.' That's what the power of photography is.

Let's assume that all the cassettes of monochrome film Cartier-Bresson ever exposed had somehow been surreptitiously loaded with colour film. I'd venture to say that about two thirds of his pictures would be ruined and the remainder unaffected, neither spoiled nor improved. And perhaps one in a thousand enhanced.
