I own a 5x7 camera, a Rittreck View. I would like to go to a larger format, and know that an 8x10 adapter back was made for my camera. But I wonder about making my own, larger adapter back, possibly an 11x14. I realize that the camera has limited bellows draw (14.5 inches with my Pacemaker Speed Graphic lens board adapter on the front). But the adapter would add inches to the length, just in order to allow the light cone to cover the 11x14 format, and I could make it even longer. I know I would still be quite limited in both the lenses I could sensibly use, and would have limited movements. But am I missing some other limitation that is obvious to others with more knowledge than me?

I made the 5x7 back for my Rittreck, and know I could make this 11x14 adapter, too. Building an entire camera might be possible for me, but beyond my budget. And the thought of making the bellows scares me.
