I wonder what system he is using to browse the images. If he is using the forums, and marking his choices that way, it will be a few months before he could go through them all. I'm hoping he had a way to batch download them and rate them in Bridge or LR. When I'm culling wedding images I can go through about 1,000 an hour. At that speed CR guy could be done with initial culling in only 13 hours!
This is a seriously big task, thanks CR guy for putting this on.
