This is similar (but reverse operation) to a design I've seen on f/295, the pinhole photography group -- which, itself, was a reinvention of the falling (glass) plate cameras that were sold in 4x5 size from around 1890 until about 1920 or so. The original falling plate cameras had a mechanism that move the plate stack forward to maintain the same film plane through all exposures, and I think the one on f/295 also does so -- one advantage of falling plates.Originally Posted by maxn
Bad news is, for a pinhole camera, you have to have a "focal" length longer than the vertical dimension of your film. Good news is, you don't have to have expensive 8x10 holders or reload in a changing bag to take more than one shot.
I'm working on a design that may solve both problems -- a rotary multi-holder design that will produce a wide-angle camera capable of three or four shots. Made in a three pound coffee can or gallon paint can, it might be possible to accomodate 8x10 in one.
