I had my first photo lesson with Benjamin today. We went to Cherokee Park (near Big Rock Creek). He taught me about the Aperture Priority mode on my camera. Basically, it does everything (once you set the ISO) except you have full control over the aperture, which is how big the camera opens when it takes a picture. That effects how much of the frame is in focus. The picture with the lower aperture makes the stuff in the background out of focus.
Here are 3 shots with different apertures:
1.4
8
16
