    Kent,

    Have you ever taken off the rear element of your Petzval lenses and looked at the reflected images on the ground glass? They look like soft focus images to me. Nice glows at highlight area and get sharper when you close down the F stops.

    No, I have done the front element swap to the rear thing on a couple. Different deal I suppose.

    It’s the “classic” Kodak 12” portrait lens. The iris diaphragm sits in front of the lens elements. The smaller the f-stop, the sharper the overall image.

    I put his forehead at the farthest edge of my field of focus to accentuate the effect on the parts and pieces of the landscape behind him. It is tack sharp when and where you want it when you work with it!
