Aperture
For these compositions i made a sculpture using paint, a ruler, and playing cards. I used manual focus, and the aperture adjustment setting. For the bottom picture I used a large depth of field and a small aperture and used a f-stop of f/22. For the top right hand picture I used a shallow depth of field and a large aperture and used a f-stop of f/2.8. I changed what was in focus but twisting the manual focus knob. The picture with a small depth of field is better, it gives you the feeling of having the items in front of you. A shallow depth of field creates more visual interest. A large depth of field should be used when u want the entire picture in focus.
