This photo is so Aidan right now, he can't give you anything but a cheesy smile right now or a scowl.
I can't quit doing my UE exercises even if it's just me doing them. I liked the examples he gave on page 32 on aperture. So anyone can do this even if they don't have the book. Pull out your manual if you don't know how to change your aperture. Take a photo of the same item to see how the different aperture settings affect the background. Here is what you are going to set it at f/2.8, f/4, f/5.6, f/8, f/11, f/16, f/22 (a total of 7 photos). Link to your photos and I'll try to get mine taken this weekend.
