What is an example of imagery in the novel, Wolf Hollow?

“The photograph was marbled with rough handling and shadows, but I could still see the sun-struck surface of a fishing hole as if I were looking down from the bridge above it… But when I flattened it out, I could see a vague reflection in the water, of the man with the camera on the bridge. A self-portrait. The kind Toby would permit himself. How he looked, but secondhand, transformed by the water (pp. 249-250).”
