Making Photographic Trays
Serviceable trays for use in developing and printing photographs may be made quickly of cardboard boxes of suitable sizes. Where one is unable to transport readily a full photographic equipment these trays will prove convenient as well as inexpensive. They are made as follows:
Procure boxes of proper sizes and see that they have no holes or openings at the corners. Melt paraffin and pour it into the box, permitting it to cover both outside and inside surfaces. If the paraffin hardens too rapidly the box may be heated and the work completed.—Contributed by Paul A. Baumeister, Flushing, N. Y.
