I often think of that quote by Leonardo da Vinci when I’m photographing flowers, particularly white callas. Perhaps it’s their simplicity that appeals to many. And perhaps it’s simplicity that makes the popularity of black and white photography endure in some circles. I took both of these photos of a white calla on a black background, one I took as a colored shot and the other began the same way but was edited to black and white. What’s your preference?
