I have taken chips back to the room, or in one case, out to the parking lot. The restrooms might work, but I'm not sure of the color correction for Flourescent lighting.

One trip to Elko I used a close-up attachment on a film camera. Got home and found that digital is the answer... You can see what you have before you are 2,000 miles away from the casino.

I always wondered how Paul got all those high price chips. Very nice work.
