Soc. Mot. Pict. Eng., XVIII, No. 2, February, 1932, p. 207) concerning distortion of the photographic image resulting from directional currents of developer generated by movement of the film in film processing machines. Simpler methods of breaking up the directional currents than those previously described have been examined. Characteristic curves from “directional pairs” of sensitometric strips, and “densograms” of uniform exposures have been used for purposes of comparison. Application of developer in the form of fine jets impinging upon the emulsion surface at frequent intervals has been found largely to eliminate directional effects. Violent agitation of the body of developer in the developing bath by injection of air gave good results, but was inferior to the jet system. Propelling the film on edge in a tray type machine offered no advantage over the horizontal film position. It is shown that under conditions found to be good from the standpoint of directional effects, distortions due to “Eberhardt effect” are present.", "abstract$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/Source Bak/smptej/10.5594_J16614.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-journal-article-nlm@v1" }, "articleType": "research-article", "articleType$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/Source Bak/smptej/10.5594_J16614.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-journal-article-nlm@v1" }, "authors": [ "J.
