I've met Jay Potter a few times while out and about on the old C&O, and
he is a very nice fellow.  At the time he was using a Pentax 6x7 camera
and was shooting b&w exclusively, but I do not know if he is using a view
camera for any work these days.

It is possible to "swing and tilt" both your negative in the enlarger and
the photo paper easel underneath to correct for converging lines on the
final print without ever using a view camera to correct vertical lines.

I do this all of the time when I print b&w in my darkroom, especially old
railroad negatives where the photographer had a building or smokestack
near the edge of the photo which angled toward the center of the image
because of the use of a wide angle lens or a camera angle looking up. 
You have to tilt the negative carrier in one direction and the easel in
the other in order to maintain focus on severe image tilting, but for
minor corrections of vertical lines just tilt the easel by placing
something under its bottom edge and stop the enlarger lens down to get
more depth of field to hold focus on the print.

The only problem with the latter method is that whenever you tilt the
paper you form a keystone-shaped image and must crop the sides a little
in order to get an image that fills your photo paper.  Unless the subject
is right up against the edges of your negative, you can do this
manipulation very easily to dramatically improve the appearance of your
final prints.

Now, the Schiempfluging of the view camera lens board and film plane in
order to get maximum depth of field is a different matter altogether, and
does not apply to printing negatives as you cannot add more depth of
field to a negative after it has been shot.

Try it, you'll like it!   John B. Corns
