When I view my pictures critically, the most common problems I have are with focusing and depth of field.
As to focusing, I notice that too often my pictures come back with the subject slight out of focus, but objects just behind are in focus. Just the opposite of what I want.
I guess depth of field is related, but it seems that a mark of many professional photos is that the subject is in focus and the background is extremely blurry- thus causing the subject to stand out. I try to do this, but it is difficult to do. Is it necessary to have large aperture lenses to accomplish this more regularly?}
