Make a viewfinder: www.pulitzerarts.org/program/art-recess-how-to-make-a-viewfinder/
Visit your local gallery and choose 3 or 4 paintings to view. For each one, look at three different views using your viewfinder. Try to close your mind to preconceptions and state only what you see from your viewfinder. See how it opens your mind? What else can you see?
