Hello...there is a post on my blog where I did some math this summer. Purely hobby oriented, not pro. I was trying to get a handle on my purchases, but is certainly not exhaustive and since was hobby, did not try to put value on my time when deriving per print costs. The password is 'film' and can be viewed at: http://oldschoolphoto.shutterfly.com Look under 'cost per print' on Sept 2nd. Cheers
