[Leica] IMG: Weston Beach and This Week's Blog

[rgacpa at yahoo.com (Bob Adler)]

Scheimpflug has nothing to do with perspective control. Your mixing apples 
with oranges. Scheimpflug when you tilt, not when you shift. Shift is for 
perspective control. Scheimpflug is for DOF *control*.

And it works for 35mm. I can get down and get a pebble in focus 2ft in front 
of me as well as the rocks at the cove entrance. You *cannot* do that 
without a bit of tilt. It isn't sharp all the way. 35 or 8x10...

Try it; you'll like it.

I don't think Scheimpflug  would not work with 35mm.
I just haven't seen how its necessary.
To shoot a building it would be great to have the back parallel with the
building so just shift the lens up but I can correct perspective problems so
fast just with the crop tool in Photoshop that I can't see getting a big fat
expensive slow non AF lens..
Scheimpflug with 4x5 you need becaue even stopped down, way down you can't
count on getting everything you want in focus.  When I use a view camera I
actually do have a clue what I'm doing and use Scheimpflug and do everything
correctly that these is to do.  Becaue I think its necessary. If you don't
you don't get ziltch.
With roll film you stop down and get it.
I was shooting f 8 and I was being there on the beach with the tidepool. The
sun way shining. My film was not all that slow. I was doing ok. I'll be
working more with those shots.
I think I shot Tri x pro 320 220 and ran it in Xtol 1:3.
