Rectangular Opening to Use over Camera View Finder

Ordinary view finders on cameras, having the cut-out in the shape of a Maltese cross, are quite confusing to some camera users. To overcome this difficulty, I cut a piece of celluloid to the shape shown, and in taking a picture, the proper opening is held over the view finder so that only the view that will appear in the picture can be seen.—Contributed by E.
