Depth of Field – 3 Objects

Understanding depth of field by varying f-stops…

Shooting 3 different objects in focus using F/4 and then stopping down to F/22 to get all three in focus. What I noticed was that I lost a bit of sharpness as I went from F/4 to F/22, which I later found out is due to diffraction.

Ken Rockwell has a pretty good article on it in which he talks about how “If you stop down more you get sharper results, but if you stop down too far, diffraction gives you softer results, just like squinting your eyes. The very best aperture is someplace between these two, and I’m going to show you how to find it exactly.”  ( http://www.kenrockwell.com/tech/focus.htm )
