Okay so I'm going to be taking a few pictures of my character and I need a cool background location.
Also;
Tips on how to get good photos/angles etc. Would be good.

If your playing on the PC you can use the console command TFC, which is "Toggle Freefly Cam." This basically allows you to move the camera anywhere but you will not be able to interact. You can position the camera to look at your character from any direction.

As for background, it depends on your character type. For example if I wanted to take a screenshot of my Archer I would perhaps have him standing over a freshly killed Deer or something.

The Valtheim Towers are always good.

If not there, anywhere in The Reach.
