(in photography): Someone, almost always a guy, who gets so caught up in the technical specs of a camera to the point of endlessly repeating stats in numerous online forum postings and arguing which camera is better solely on specs; who conversely almost never takes any pictures.
"Did you hear Phil got a new camera?"
"Of course I did, how could I not? That measurebator has been spewing nothing but megapixels and JPG and RAW and other crap ever since he got it. The only way to shut him up is to ask to see a photo he's taken with it."
