A photograph asks you to be objective about the subject matter of the dream. Step back and look at the present moment rather than everything that lead up to it.
It may hint at you thinking about photography in someway the day before. But a dream about a photograph maybe a symbol for something much more abstract.
Dream symbols are important because of the emotions that we attach to them. A dream aboutb a photograph may simply represent your interest in photography.
For instance, a photography dream may link to a thought such as “I have to look my best” as a photo captures people as they are and this can emphasise how you look good or bad.
A photograph captures reality and so it maybe a symbol for the imagination as you try to recreate reality as it happened.
