The use of a frame can turn an otherwise plain picture into a pleasing one. Usually a foreground element is used to create the frame. Examples are an overhanging tree branch, a window frame, a door, arches, a fence, rows of trees, etc.
We’ve all heard about foreground and background. Generally the foreground is where you find the main subject. The background is, well... in the back. It’s just back behind everything else, right? Wrong! The background is just as important and in some cases even more important than the subject itself. How is that even possible you ask?
