When we view a flat two-dimensional print which is a representation of a three-dimensional scene, we can often recreate this sense of depth in our mind’s eye. Using any perspective present in the image and the scale of known objects we view the image as if it exists in layers at differing distances. Successful compositions often make use of this sense of depth by strategically placing points of interest in the foreground, the middle distance and the distance. Our eye can be led through such a composition as if we were walking through the photograph observing the points of interest on the way.
A greater sense of depth can be achieved by making optimum use of depth of field, careful framing, use of line, tone and color. In this way the viewer’s attention can be guided through an image rather than just being drawn immediately to the middle of the frame, the point of focus and the principal subject matter.
