Divide the picture into nine parts visually and examine each section. Although you may learn things from the text related to the photo or the person who took the picture, you can also draw inferences from the picture itself. Or, you may wish to invent a story. Use the facts you know about the world, history, and science to come up with your own characters, plot, and setting. Like discussing a poem or song, a visually literate person could talk about a single visual for an endless period of time.
Visual comprehension goes beyond description.
It involves explanation and understanding. Here on This Spot the story is told visually by examining the changes that take place in a single location over thousands of years. Use books as examples to help students in reading visuals. Many visual stories can be told this way through exploring changes over time in a building, river, or object. Once students become confident in reading visuals, they need to begin interpreting visuals.
