Describe what you see. Not everyone sees what you see, so your description is important. It forms the context for your interpretation.
To miss symbolism and metaphor and see only the literal is to misunderstand the expressive aspects of art. But be careful not to presume anything at first. Remember that your interpretation is part of the discourse of a community-one that you belong to. The artist does not own the meaning of the work.
What the artist thinks about an image should be one of several competing interpretations of the image.
– What is this image about? (This not expressing your likes and dislikes…tell us what you think the artist is trying to communicate)
– What do you believe is the purpose or intention of the work?
