Final Exposure.—The strip of the plate whichshows the best detail and contrast is the correctlyexposed part, and after this experiment an actualradiograph will be successful if the same exposurebe given and the same proportions of developer atthe same temperature used (see Plate III.). In choosing between the strips it must be borne inmind that a longer exposure is required for thewrist and palm than for the finger-tips, and that acompromise must be made between them to get thebest general effect.
