First of let me say "Heya Folks, missed ya!"... Geez, hope y'all even remember me. I think I was last on the site about mid 2005 or so.
Anyways, my outdoor photography has netted me a few pics I'd like to blow up to maybe 16"x20" to display on my wall.
What is the lowest resolution the original can be in and not look pixelated when blown up to 16"x20"?
Thanks!
