Hi there! I just joined the "Club" and thanks for the invite and info. I've
been subscribed to this list for quite a while now but not had any real
reason to have a say. Now, however I have a question that someone may be
able to help with.

I currently use a Russian "Horozont" version 1970 etc. Also in completion
stage of a 120 pinhole pano with 6x 20 cm neg. using curved film plane
similar to Mottweiler concept, but with ability to use small focusing screen
on the film plane to check picture etc prior to exposure. 

I have just scored a schneider 90mm super angulon F8 in mint condition and
will soon build a 6x17 or similar around it. So, I want to know if I curve
the film plane to allow for light fall-off to the edges of the neg will
those outer edges still be in focus as say the centre of the image directly
opposite the back of the lens??? Or do the angles built into the super
angulon grind patterns only allow for a flat film plane to stay in focus??
In which case I will have to fork out big bucks for a graduated ND filter
eh? Look forward to hearing from you down here in New Zealand.

Yours in photography etc ..Julian
