Photographic means to do with photographs — making them, using them, or belonging to that craft. A photographic exhibition shows photos. Photographic paper is the special paper prints are made on. Photographic evidence is a picture used to prove something. The word is a little formal; in speech people often just say photo, as in photo album, not photographic album. People also stretch it. A photographic memory is the claim that you can remember a page as if you were still looking at it — though actually true photographic memory is rare, and scientists argue about whether anyone really has it. You may also hear in photographic detail, meaning very clearly, like a sharp picture. Those extra uses still rest on the main idea: like a photograph.
