Photographically is the adverb: in a way that uses photographs, or in a way that is like a photograph. You record an event photographically when cameras, not just words, keep it. Something is photographically documented when the proof is in pictures. People also use it for how clear a memory or a description is: she remembered the room photographically, meaning every little thing, as if a camera had been in her head. It is a formal, slightly heavy adverb; in easy speech you would say in photos or with a camera instead. The adjective photographic sits before a noun (photographic paper); this word tells you how something is done.
