This maybe way too obvious for everyone on this board, but I thought I'd throw it out there anyway. Magazines, newspapers, yearbooks etc. want 300 DPI photos. I found out recently that I was saving my photos at 72 DPI and the high school year book said that when they went to process them at 300 DPI, the photos degraded. I'm a new shooter so this was news to me. I bring it up only so others don't make the same mistake.
