International photographer (Jan-Dec 1935)

January, 1935 The INTERNATIONAL PHOTOGRAPHER /•/,-< affecting it to correspond to that embraced by the usual lens used on the camera. You will find that by using a reliable meter, on development, all the negatives in the roll of film will be of practically the same density. It will also mean a decided reduction in failures. An Unusual Fact: The Sease No. 3 paraphenylenediamine formula is rated as capable of giving twenty diameter grainless enlargements when mixed freshly with pure chemicals. The Edwal Laboratories informs that if the chemicals for this formula are weighed out, mixed together in a dry state, and allowed to stand for several months, then dissolved in hot water produce a red solution which will give a much finer grain than the freshly mixed Sease No. 3 formula. On standing the mixture acquires a pink or brown color, finally turning black. The Edwal Laboratories stress the fact that only pure chemicals should be used for this purpose, otherwise a considerable amount of tar is formed which cannot be dissolved. Here is a new angle for experimenters to work on. FEUSS OPTICAL BENCH R. Peuss, Inc., announce a real universal optical bench in every sense, indispensable in colleges, high schools, industrial and research laboratories and wherever optical principles are studied or demonstrated. A new and ingenious construction enables them to furnish an extremely flexible, accurately machined, precision apparatus, at a very moderate cost. It possesses certain salient and distinguishing features: The overall bench length can be increased at will very inexpensively, simply by inserting the longer bar. In present type precision benches, a length of two meters, for example, is very costly. The Variable Angle Base opens up an entirely new field of experiments with an optical bench. It is possible to demonstrate the phenomena of spectroscopy and spectrometry, to study diffraction, refraction, Zeeman effect, Kerr effect, etc., and to perform many experiments witli polarized light, not possible with a straight bench. New and ingenious devices recently developed by R. Feuss, Inc., permit experiments or demonstrations long desired by workers and instructors in optics. Such attachments or devices, as the reader may already possess may be fitted for use with Feuss Riders and they take pleasure in offering this bench to all workers in optics and physics and recommend it as intrinsically accurate, convenient and economically priced apparatus. The equipment is manufactured in the shops of R. Feuss, Inc. NEW MINIATURE CAMERA CLUB The first meeting of a new miniature camera club, to be known as the Miniature Camera Pictorialists of Los Angeles, was held Wednesday, December 5, 1934, at which time Tom J. Hopkins was elected director, and Robert E. Saltmarsh, secretary. Meetings will be held on the first Wednesday evening of each month at 942 Westwood Boulevard, Westwood Village, Los Angeles. Membership will be limited and will be by invitation only. The purpose of this new organization will be to advance pictorial photography with the miniature camera. There will be talks and demonstrations by prominent workers and manufacturers' representatives. Outings will be arranged. All members will submit one print each month to be judged by a jury selected from the membership. Prints so selected will be held for a permanent traveling exhibit. There will be an international salon of miniature photography, information concerning which will be forthcoming at a later date. The present membership consists of fifteen workers. Correspondence should be addressed to the Secretary, 1516 Westwood Boulevard, Los Angeles. A WORD FROM PAUL PERRY Paul Perry writes from Manila, P. I., where he is now located, gives his friend, Charles P. Boyle, the low down about cinematography in the Orient. Paul is now head of the color department of the Philippines Film Company and he is just completing his new laboratory. Mrs. Perry has joined him and they both like their new home. About February, Paul will go to the Southern Islands to shoot color stuff and will then go to China to make shorts. He expects also to visit Japan, and Singapore before returning to Manila.
