Amateur Photographer & Cinematographer (1933)

th[ amateur photographer a -6 ClhEMATOORAPHER o Perusing Peru. “ . . . The wonders of each region view, From frozen Lapland to Peru.” So wrote the nineteenthcentury poet, but he never foresaw photography from the air, which made his dream come true. The latest country to be surveyed — and pretty adequately — in this way appears to be Peru, where an American expedition has been carry¬ ing out photography at elevations of over 25,000 feet. The expedition set out with two cabin monoplanes, one for photographic work and the other for transporting supplies. The photographic plane, in addition to being equipped with the most recent and efficient photographic apparatus. had a supercharged motor, which made it possible to reach altitudes of 28,000 feet. Besides the hundreds of air photographs, a large amount of motion picture him has been exposed throughout the coastal region of Peru and the western border of the Andes. The photo¬ graphic leader of the expedition, Mr. Johnson, is an American spe¬ cialist in air photography, and had already served as chief photographer with the Peruvian naval air service, in which capacity he had taken many hundreds of photographs. It strikes us that soon the world will contain no single lonely spot which has escaped the eye of the camera. April 5th, 1933 Victoria and Cinematography. Queen Victoria died thirtytwo years ago (on January 22nd, 1901) and not everyone nowadays realises that she saw cinematographic pictures. Lord Lee, of Fareham, speaking at the Royal Empire Society a few days ago, recalled that the queen mentioned the fact in her journal for 1896. “ We were aU photographed by Downey by the new cinematography process,” she wrote. “ We walked up and down and the children jumped about.” Later in the same year (1896) the resulting film was shown at Windsor. “ The so-called ani¬ mated pictures ” she called them in her diary. The Amateur Photographer*’ EXPOSURE li ABLE — April EVERY MONTH a brief exposure table will be provided for the assistance of our readers in their practical work. A glance at the current approximate exposures as here given will serve as a reliable guide for most purposes. The subjects will be varied to suit the time of year. The following exposures will serve as a working guide for any fine day during the month, between the hours of 10 in the morning and 2 in the afternoon, with the sun shining, but not necessarily on the subject. Stop used, f/8. The exposure should be doubled if the sun is obscured or if stop f/ii is used. For f/i6 give four times the exposure. For f/5.6 give half. From 9 to 10 a.m. or from 2 to 3 p.m., double these exposures. From 7 to 9 a.m. or from 3 to 5 p.m., treble them. N.B, — The times given above are by “ sitn time." The exposures, therefore, which are laid down as suitable for 2 to 4 p.m., for instance, will be those to be given between 3 and 5 p.m. by the clock, during “ summertime” which begins on April gth.
