Is there a camera mode?

I want to get rid of the UI for a second :)

Yes. Press the "`"/"~" button (just under the ESC button) and use the following commands:
tfc 1
- this makes the camera move independently of the player. Good for getting a better angle. Remove the '1' if you don't want everything to freeze.
tm
This removes the UI. It will remove the console UI too, so make sure to press ~ again to close the console (and to bring it back up).

To disable these commands, just repeat them in the console - i.e. tfc and then tfc will enable free camera and then disable it.

Other useful commands:
fov ****some number**** (e.g. "fov 40")
This changes the FOV (field of vision) to that number. 65 is default. I find 40 is best for character shots. 10-20 is good for extreme closeups. Also, it will go back to default when you close the game.

sucsm ****some number****
This changes how fast the camera moves in free camera mode. 1 is a good setting for character shots. I think the default is 5, though not sure. It will reset after exiting free camera.
These commands are perfectly safe to use, BTW. Some others aren't, so do beware of that.
