In the early days of photography, photographers had no choice but to shoot in black and white, as it was the only available medium. Then, in 1936, the invention of kodachrome gave colour photography to the world. But black and white photography didn’t die off, instead it flourished. Modern black and white photography at it’s best is art, and many photographers regard it as the purest form of photography.
So why does black and white photography command such acclaim? One reason is that colour is a distraction. It takes attention away from the visual building blocks of a great photo; texture, tonal contrast, shape, form and lighting. A photographer shooting in black and white has to learn how to use all these elements to create a memorable image.
Another reason is that color photography, much of it mediocre, is so abundant that black and white makes a refreshing change.
From an artistic viewpoint; color depicts reality. Black and white is an interpretation of reality.
