Okay, like you all know I have a D80. (10 mp) I took some ISO 100 pics from the desert that I want to print out for my wall. What max size do you think I should consider?? Is 10 x 15 too much?? I've also heard of some pretty good enlarging programs, should I try those out so I can get monstrous pics?? Basically I'm brand new to printing and I just want the low-down. Thanks!!
