Modification of Wista 6X7 Back : LUSENET : Large format photography : One Thread

I've finally picked up a roll film back. It is the Wista 6X7 back. It looks like it would be very easy to enlarge the mask in the front of it to make the opening 6X9, and the pressure plate covers that size. I also realize that it would be necessary to shoot every other exposure if I'm shooting 6X9 since the advance wouldn't move the film far enough to get all 6X9 of it out of the way. Seems to me I could make this modification and shoot 6X7 if I still wanted to (there would be overlap on the area I didn't compose on either side of the image) or go 6X9 by skipping every other exposure. If this is a really dumb idea (I can't tell) let me know your thoughts on this. Also, does anybody know where I would order just the mask part so I don't have to alter the 6X7 one? Thanks for your responses. I read about this thing in the "Top 25 Roll Film Backs of All Time" and I just had to buy one.

If you re going to shott much 6x9 then it seems to me you'd be better off buying a 6x9 back. Wasting ahlf a roll of fim willpay for the back petty fsast if you do any shooting at all.
