i got a 11x14 camera a few years ago when
i decided that i liked shooting paper negative portraits ( 8x10 )
but wanted something a bit bigger. i traded some images for century 8a camera and its semi centennial stand
... but the camera didn't have a 11x14 back just a 8x10 ...
so i made a back, and book style paper holders out of foam core and matboard
and with the advice of thomas sauerwein taped some waxed paper on the back instead of ground glass ...
it works amazingly well ... eventually i happened upon a 7x11 back and film holders that i also use ...

i like the long format for portraits and shooting paper works for me since i am too broke to buy film
