Daido Moriyama is a street photographer that shoots in monochrome purposefully. Not because all the photography masters shot in Black and White. Not because Black and White pictures are evergreen. These are the reasons why Daido Moriyama shoots in Black and White.
The reason why I think black and white photography is erotic is completely due to my body’s instinctive response. Monochrome has stronger elements of abstraction or symbolism. This is perhaps an element of taking you to another place. Black and white has that physical effect on me. That’s just the way I respond to things.
One distinction I can make—I’ve written about this in my essays: black-and-white photography has an erotic edge for me, in a broad sense. Color doesn’t have that same erotic charge. It doesn’t have so much to do with what is being photographed; in any black-and-white image there is some variety of eroticism. If I am out wandering and I see photographs hung on the walls of a restaurant, say, if they are black and white, I get a rush! It’s really a visceral response. I haven’t yet seen a color photograph that has given me shivers. That is the difference between the two.
