70mm backs - is bigger than 6x9 possible?

just wanted to ask - can you get a bigger neg than 6x9 if you use

70mm rollfilm? or is it the same choices: 56x70mm, (6x7) 56x83mm,

(6x9) etc.

 

I wondered if anyone makes a back using unperforated 70mm that gives

you, oh, I don't know, 62 x 90 mm ?? I'm looking to get a little

more out of the hieght than 56mm... something halfway between 6x9

and 4x5".

 

btw: I'm not talking about the panoramic backs here, (6x12 or

whatever), thanks,

Mark has it right, but you can roll your own 116, 616 spools with 70mm and

get whatever size image the folder or camera is capable of. Problem is aero

and color film are your choices in big rolls although J&C will have #116 b&w

spools in stock this year. I have not seen real big 70mm backs for LF cameras

although Graphic did produce the RH50 (6x7) and XLRF 70mm back. Check

Ebay.
