Picture a commercial photographer twelve years into the job. About 60,000 keepers on the drives, after the culling. A client calls and asks for the shot of the red chairs on the stage from one of their events. Or something like it. Wider, if she has one. She can see the picture in her head. She can’t say which event it was. And her keywords from those years are patchy, because nobody keywords properly at 1 a.
