To get a closer screenshot you may need to change your camera view in the game settings. Using the Sims 3 camera style you can get a much lower angle.
To change to the Sims 3 camera style go to the Options menu > Game Options > Game Camera - then check The Sims 3 Camera. (Click image to see larger view)
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.
