Hey Spaz nice for starting this. I'll post a bunch later in the day. Try using this maneuver I found to take more of your screens:
Ok so first of all you need to disable the map and the rest of the hud in the main menu under display. Secondly you need to get a large vehicle like a van or a bus. A van works great.
Now just drive up to the place where you want to take a screen and let either the left or right side face your scene which you want to shoot at.
Now just make sure Toni stands as near as possilble beside the van with his back facing against it. Now pan the camera by holding the left trigger and pressing left or right on either the d-pad or analog stick (depends what control setup you use).
Do this until the camera faces the other way. You will see Toni dissapearing as the camera are now basicly against the van. Then just enable the cheat menu and take your screen!
An example of screens taken using this method:
