Re: [Leica] Keystoned images

Well, guys, 'tho I'm an M devotee (even have one on the Illumitran 
with Viso, vertical finder and 65 Elmar), I think in this instance 
you using a pair of pliers when you need a screwdriver.

I just finished up a similar project - also for a friend - and what 
was too large for the copy stand was mounted on a wall against a 
black backdrop,  The camera was a Nikon F3 with a grid screen which 
would readily show keystoning problems.  I also used a small spirit 
level to position the camera and the subject.  In one case, the 
painting required some shimming at the bottom with an empty paper box 
to get it to hang plumb.  From that point, with the grid screen I 
could make the necessary final adjustments.
