To us, frames are typically doors and windows, so there may be a suggestion of something else within. Use of rectangles and the more specialised form of rectangle, the square, are a design device of splitting the overall frame into parts, the most classic of these being the Golden Section. As a consequence, because this organisation is no longer implicit, rectangles need to be positioned carefully in order to have a well designed image.
