Hello All, I currently own Lightroom 4 and I am considering upgrading to Lightroom 5. My question is does any body know if there is any difference between the "upgrade" version and the Student Teacher or "full" version? I know the upgrade is cheaper but I can also get the full boxed version at around the same price due to my niece getting a student discount. I assume it would be the same but I want to make sure I am getting the same product either way. Sorry in advance if this is a repost. Thanks!!
