Want to take a screen shot of the front.

If you holster your weapon and enter 3rd person you should be able to spin the camera to see the front.

Tap 'v' key (default) to switch to 3rd person. Then hold 'v' and move mouse till you get desired angle, scroll wheel to zoom in/out. Holster weapon first, otherwise you be stuck in over-the-shoulder view until you do.

edit; Ninja'd

Thanks guys.

I wish there was a way to make a screenshot with one of the cool augmented weapons too, but as soon as I unholster a weapon the camera snaps back to over the shoulder mode. Though I think I remember seeing some "selfies" with people holding weapons, but I may be wrong.
