Beneath the Carriage of the 200-Inch Lens.
a Bell & Howell Filrno 70-DA camera, fitted with an /: 1.5 15mm. lens, an /: 2.7 one-inch lens, and an /:4.5 two-inch lens, and began making tests with Supreme negative. Since I had been told that a very great range of 16mm. laboratory work was available, ranging from good to bad, with the former none too plentiful, I sent my tests to several laboratories, not onl\ here but in points as far distant as San Diego and New York.
The results were none too promising. Almost without exception they indicated I was not getting enough exposure to give a satisfactory negative. It began to look as though making a movie of the project would be an impossibility. But I resolved on one more test. This, I developed myself, putting through a hand-test in my still darkroom. It was successful. Inevitably, with my crude developing methods, the test-strip was badly scratched, and the grain-size was by no means of the best: but the developed negative revealed ample printing density, and proved that the film definitely had plenty of speed for the job.
Cooperation From Agfa-Ansco Lab.
Armed with this test, I next went

to the Los Angeles Agfa-Ansco laboratory. to see if their experts knew of any lab which could handle my negative. Here I was referred to H. A. Deahoff — and the worst of my troubles were over. From him I learned that this plant, which I. in common with many others, had always thought devoted solely to reversal processing, is now equipped to develop and print 16mm. negative as well.
Too much credit cannot be given Mr. Deahoff and his staff. They have handled all the processing of my picture, and I can truthfully say that without their help, it could never have been filmed. Moreover, they went far out of their way to make my work a success. Deahoff came over to Pasadena with me, and studied the problem thoroughly, then returned to the lab and mixed up a special fine-grain paraphenylene-diamine type developer for my negative. The result is a negative of excellent density, gradation and grain-quality, which is a credit to Agfa Supreme 16mm. negative and to the laboratory behind it.
With this basic problem solved, the rest was largely a matter of deciding what action must be filmed, and shoot
