EXPOSURE OF SENSITIVE PAPER.

A frame for holding a number of sheets of prepared paper is provided, and is furnished with a paper case at the back.

When about to operate, the number of sheets of paper required are placed in the paper case at the back of the frame, which should be shut down close to prevent air or light entering to injure them. It is placed either in the bottom of the Camera, or in the bag, and after obtaining the focus with the ground glass, as for the collodion plate, the paper frame is opened, and the first sheet of paper removed and placed between the paper case and the glass.

The frame is now closed, and placed in the sliding frame, and the paper exposed to light the requisite time. The frame is then removed, and the paper transferred to the back of the paper case. The operation is then repeated, with the next sheet in front.
