What I learned

I saw the great differences between the aperture priorities and program mode. My favorite is the F/22 F-stop, it just has the right balance. It focuses on what I want the viewer to see and blurs out all the junk I don't want. Program mode does almost the same at the F/22 F-stop but not as good as the F/22 F-stop. The only reason I would use the F/5.6 F-stop is if I was taking macro shots and need all the detail I can get. It would also be good at taking great texture shots.
