Amateur Photographer & Cinematographer (1935)

January 2nd, 1935 Ihi AMATEUR PHOTOGRAPHER p 6 CINEMATOGRAPHER o should be about what is on the screen at the moment. Not many brains are capable of the dichotomy of taking in one thing by the ear and another different thing by the eye, and if while things are happen¬ ing on the screen the talk is about matters in general, there is a sense of frustration whereby both the graphic and the audible record lose in appreciation. Another point which has been followed in the “ Secrets of Nature ” films is to arrange for the description to begin a moment or two ahead of the picture happening, the reason being that it takes longer for the brain to interpret a message received through the ear than to interpret one received through the eye. Bv the time the meaning of the words has dawned upon the brain the picture has appeared. Coughing in Court. To hold a camera for exposure and at the same time to cough suggests some amount of difficulty, but as Mr. Jarche told his R.P.S. audience the other night, the cough is a necessary item in the Press photographer's ritual. Before pho¬ tography was disallowed in courts there would be a regular chorus of coughing, so as to excite a remark from the bench ; the coughing was the cover for the click of shutters in cameras peeping from behind bowler hats. But Press photo¬ graphers have to be acrobats and contortionists and full of adaptability to the circumstances of the moment. Suppose you were asked, as Mr. Jarche was by his editor, to go to Bond Street, to a fishmonger’s, where there is a tortoise in the window, request the loan of the tortoise, and place it on the Bond Street pavement, and photograph the reactions to it of each passer-by — high and mighty dame, messenger boy, postman, club swell and so on. It is worth while to relate one of Mr . J arche ’s adventures in Hyde Park . A charming lady and gentleman on horseback noticed him, posed for him, and gave him their name. It was the name — two film stars of the first magnitude, just married, for whom battalions of Press photo¬ graphers were searching in every corner of the land. Mr. Jarche rode back to his office on the wings of the wind, word went round to all the papers that the great scoop was coming, with palpitating heart he was pushed into the dark-room to develop his negatives, and found — that he had forgotten to load his slides on going to the park ! The A mateur P hotographer ” E XPOSURE T ABLE— January 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 11 in the morning and 1 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/11 is used. For f/i 6 give four times the exposure. For f/5.6 give half. From 9 to 11 a.m., or from 1 to 3 p.m. double these exposures. From 8 to 9 a.m. or from 3 to 4 p.m., treble them. Subject. Ordinary. Medium. Rapid. Extra Rapid. Ultra Rapid.

As a further guide we append a list of some of the best known makes of plates and films on the market. They have been divided into groups which approximately indicate the speeds referred to above.
