I'm not sure if this is the information you're looking for, but this is the way I use the camera in Sims 4.
Use the mouse, it's scroll wheel and arrow keys to get photos. Press the scroll wheel down down while moving the mouse to rotate the camera, scroll in and out to zoom in and out.
Or by keyboard, hold the Ctrl key and click and drag to tilt and turn the camera around to your liking.
Use the scroll wheel or up/down arrow keys to get a closer view, once you get to the angle you want.
