Thanks Frank.
Everything else aside, I tried cropping this down to its essentials: Close-up of the board and the two players' faces, but I just didn't like the result.
I should have gone 2.8 @ 1/500th, and really don't recall why I didn't. It would have cleaned up the background somewhat, but because I wasn't prepared to move the chairs for fear of disturbing the players, I don't know how much cleaner it would have been.
I'll do better next time.
Robert
