Hi Scully, if you want to improve the rendering for photos, go to the edit menu, to preferences, to the graphics tab, and hit the 'advanced' or I think its 'custom' button. Then you can boost all the settings as much as your graphics card allows to improve the looks for photos.
Remember to turn them down again to move around, cause when you max out the graphic settings it really reduces your frame rate badly.
If you want to 'cam' around to get better viewing angles for shots, hold your ctrl alt buttons down and move your mouse around, this will pan your cam around. Returning to normal just releast the buttons and hit one of your arrow buttons.
