Normal iPhone4S Lens vs. Wide Angle Lens

Normal Lens:  A standard shot (untouched) from my beloved iPhone4S, facing towards the sun.  The background is underexposed and the trees barely fit in to the frame.

Olloclip Wide Angle Lens:  Same exact shot as above (still untouched) standing in the same spot, however this time the wide angle lens is able to capture more light, all of the trees, plus the parking lot.  The shot above only caught two trees, but the shot below caught three, and almost five.  Notice how the trees towards the outside of the frame start to curve inward.  Also, notice how there is more depth to the image, and how everything seems more distant.
