The best way I've found to do it is to host your own multiplayer game. press 'SHIFT+~' to bring up the command window and type 'devmap ' then what ever map you want to use. This enables the commands for the game. I generally use the deathstar map because of it's range of light values gives me virtually every lighting condition.
After your in the game use these commands to work the camera.
cg_thirdpersonrange **
in & out
cg_thirdpersonangle ***
left & right
cg_thirdpersonvertoffset +/-**
up & down
So basically the commands would look like this,...
Linear Mode
