Many photographers know how to use contrast to benefit their photos. Contrast makes photos eye catching and can even make the most basic looking photos look great. There are two types of contrast:
Many excel at shooting photos with good tonal contrast. A good example of tonal contrast are silhouettes. The foreground is completely dark while the background is properly exposed. This works well because there is a sharp difference between the dark and light areas.
Color contrast is used less frequently because many people do not think about it. Capturing a photograph with good color contrast is more difficult than tonal contrast, but it is still quite easy. An image with good color contrast can look great even without any tonal contrast.
