Black and White
Black and white photography once was the only way to go. And after the color film came, it still survived. More and more it is seen as a different form of art, then just 'photography'. When you take pictures in black and white you are leaving out color. You create something that does not look like reality. By leaving out color other things become important, like form, texture, gradation. Taking black and white photos is something quite different, than just leaving out the color.
