“Narrative” implies the passing of time, because change, a certain development, is taking place. Narrative photography would therefore look something like a photo novel (phantasy) or at least a flashburst sequence of a few seconds, capturing a movement (reality). You can guess “what is happening” in a photograph, but you can never be really sure, things may look like they do for that one single moment only (and never before or after). The suggestion may be a perfect lie, if we consider reality to be the truth.
