Question about Taking Pictures

This probably sounds stupid, but many people take screenshots at ground level looking upwards and all sorts of angles....

How do you take pictures like that?

Create a camera and mess with the AoA (angle of attack - I think it's attack)

You can right click on the editor screen and hold it while moving the mouse button, hold ctrl and right mouse button and move around, mouse wheel to zoom in and out, or shift click to move in and out and I think thats it.

Shift+ Arrow Keys also zoom in and out. Right and Left Arrow Keys rotate.
