A clear response to a photograph starts with a clear description. For images credited to John Burwell, make a short inventory of visible forms, their positions and the direction of light. Avoid evaluative words at first. This gives your later interpretation something specific to rest on and makes it easier to explain your response to another viewer.
Next write a sentence about what the arrangement suggests to you. Compare that sentence with your inventory and identify which details support it. Another viewer may make a different reading from the same evidence, and that difference can be productive. Treat visual analysis as a reasoned account of your experience rather than a claim to know the photographer's intention or the full circumstances behind the frame.
