Pattern, on the other hand, is a continued visual element that repeats across the image frame. Since it is based on repetiton, the strongest patterns fill the image frame from edge to edge. When a repetitious visual element fills a frame, the viewer has the sense that they are seeing only a portion of the pattern area and that the pattern continues in the imagination outside the image frame. This is why patterns that do not break before the image’s edge are the strongest to photograph.
