I was working on this shot, trying to get these old hands and markers to glow a little and figured I'd try a burst of flash just before grabbing the exposure. After a couple of direct hits from my SB800, now the hands don't glow much , if at all. Is this possible? If so, others should be warned. I'm not really upset about it. There wasn't much luminous-ness left in this old watch to begin with. I like the shot, at least.
