I've been buying economy prints from mpix/shutterfly recently. While they're great for prints given to older family members, I'm finding the color & exposure to be significantly off from my calibrated monitor. The exposure can be off by 2 stops sometimes. My wife wants me to order a significant number of family photos for photo albums, so I'm looking for something that will be much truer and will last. I don't know if it's just that I'm buying economy prints and should be buying one of the more expensive options, or if there are better companies out there I should be ordering from. Any suggestions?
