Emphasizing with B&W
Black and white helps to learn the basics without getting too distracted; this is one reason why it is so popular among teachers. Black and white focuses the attention on form, shading, pattern, and other graphic concepts, to give them an unusual quality with tone and hue.
With a clear view toward graphics, composition, and design, the photographer can concentrate on:
- How contrast creates lines and how lines lead the eye or psychologically affect the viewer by curving, lying flat, diagonal, or vertical.
- How shapes or lines make a pattern and how shape with texture gives an object form.
- How highlights compete for attention and dark tones create an important negative space.
Many artists prefer black and white because it causes the photographer and the viewer to see the world in a way that cannot be seen with the naked eye.
Seeing the reoccurring pattern, line, or shape is easier with black and white, which does such a good job of emphasizing it. This is especially the case when a black and white photo shows good contrast – when the blacks are black, the highlights are bright, when you can still see some detail in both the highlights and the shadows.
