I was speaking about add a screenshot function here :

I think the best way to add a sreenshot function for Skyrim on consoles was to use the same function Skyrim use to the picture for the savegame, but without resize it to a lower resolution.
So, I think they can easily do it, add a button in the menu, when you will open the menu to take your screen, the action is already "freeze", so just choose where you want your screen saved, or save it to the default picture folder of the PS3.
Then, if they want to get paid for it :
They can add it to a dlc or something like that, then improve the idea and let us move the camera around our character, then screen.
They can also add new trophies to the game, wich you get if you screen some beautifull or secrets locations of Skyrim.
So, please Bethesda add it, everyone will be happy

About the video, it's probably more difficult but amazing. However If they just add a screenshot function I will be happy, nevermind.
