I've recently been getting into modeling & have a few photographers talking about TFP/TFCD. I know what it stands for - time for print & time for CD, but what does that really mean? Also, what should I expect? [pros? cons?] I know it's no money to me, and I don't have to pay the photographer, and while that benefits me by starting a portfolio with a professional photographer; what does the photographer get out of it? Thanks!
