Nonphotographic → It is formed from "non-" (meaning not) and "photographic" (from Greek "photos" meaning light and "grapho" meaning to write or draw). The word "nonphotographic" means not related to or not involving the writing or representation of light, typically in the context of images or photography.
Think of 'not' ('non-') related to 'writing with light' ('photographic') — that's why nonphotographic means something that does not involve light-based imagery.
