Knowing how to use contrast will help you create eye-catching images. Contrast is a tool that photographers use to direct viewers’ attention to their subject.​Tones are normally described as high, normal or low. A high tone image mainly includes white and black with few or no middle grey tones. A normal tone image will have elements that are white, some that are black and many middle tones of grey. A low tone image is the one with almost no highlights or shadows; all the tones are very similar one to the other. High tone images are harsh while low contrast images are soft.
