hi sam! thanks for your suggestions :) i was mostly concerned about a shadow on my paper/film when it was being exposed if the box stuck up / down too far. as for not having light enter the camera from the sleeves, i was thinking of having a baffle. or just a sleeve inside a sleeve that could be unrolled once my arm was "in there". too bad i can't make a 8x20 grafmatic type back :) - john
