Yes I am stupid, but at least I know it. Now, that out of the way, here's my problem: I just now noticed that when I import raw files into photoshop as 240 PPI it will allow me to print it at 16x10 (image size), whereas when I import it as 320 PPI it only allows me to print it at 12x8 (image size). ok, can someone explain this to me in small words? I get that there's probably some math thing going on - but why would someone choose a higher ppi if you can only print smaller sizes?? Since I started I had been importing as 320 (because I read it somewhere that it was the best to do), and now I'm wondering if I shouldn't just reduce it to like 100 or something if it allows me to make bigger prints without any degradation So yeah, dumb it down for me please.
