I've been abusing the look at camera feature since it was patched in. I switched it to Home, since Pause|Break is the SweetFX update key (default, anyways, and there's no reason to change it like most any other hotkey)
I started using SweetFX again a couple months ago (It stopped working with either GeForce Experience or one of the graphics card patches and I never set it back up) and I am mindblown by the fact that I managed to go two months without it. The world is so bland without it.
I'm not a scenery screenshot taker, I mostly just take pictures of my character and make scenery gifs.
Anyways, SweetFX is the best. You can set it up any way you want - bright and colorful, dark and gloomy, sharp and realistic, just a touch up, whatever. So I really recommend it if you're on PC and your graphics card can handle it. It will immensely improve your screenshots. Plus, if you do it right, you might never need to edit your screenies. :P
