Sometimes we do the same job exactly the same way for so long that it may appear that our way is the only way it properly can be done. I have been using View Cameras for more than fifty years with excellent results. But!
Today I read in another thread a comment concerning a "Focusing hood" on a B & J camera back. That it could interfere with the focusing loop when checking multiple areas of the ground glass for sharpness. This comment started me to think about it. I understand I think what this means. But do I really? I would like to have input here from "The Old Pros" Those that have been staring into the ground glass for more than ten years or so. What do you do to assure that what you are photographing will be as sharp as you want it to be in the finished print?
My technique that has worked so well for me, may be totally incorrect!
If working indoors or outdoors regardless of what the subject may be, I compose and focus so as to get main subject as sharp as possible. I do this focus adjustment with an optical aid usually near the center of the focusing panel. At this point I can stop down, and expose film. Or review what I actually may want to capture on the film and modify it by extending or shortening DOF. I don't own any kind of DOF scale, but I do know by heart the characteristics of each of my lenses. I do not stop down to f 64 and try to see a sharp/unsharp area on the darkened GG. I re open the lens (WO)to either adjust the sharpest point nearer or further from the original point of my original focus. Backfocusing or forefocusing to move my DOF zone into the location that gives me maximum DOF for the subject. Stop down to my shooting aperture and expose film.
When using moderate swing and tilts the same technique works as long as standards front and rear are parallel and the front and rear tilts are matching.
99 percent of my viewing with an optical device is with the lens wide open.
I do not move it around checking focus after I have found the infinity point.
I do not need to check the GG with the lens stopped down since I know what I want in focus is within my chosen DOF zone. As I said above perhaps I am wrong, and will have to learn a new way to do things. But I sure have had a good time doing it even if it is wrong. Waddya think?
