Book 3 — Rectangular Opening to Use over Camera View Finder

The Rectangular Opening Allows Only That Portion of the View to be Seen Which will Show on the Picture

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.
