While it may not seem like an important subject, there’s actually quite a lot that the corner of a room can offer regarding viewing. It offers a sense of depth that isn’t present within other pieces, showing the meeting point between the two or three background subjects, mainly being the walls and the ceiling. The walls and ceiling could also house other subjects, such as windows, picture frames, or other decorations. Based on the subject, this could also play into the effects of the lighting in the picture, being either the main source or a secondary source that catches the viewer’s attention.
