Amateur Photographer & Cinematographer (1933)

August 2nd, 1933 Tw AMATEUR PHOTOGRAPHER ■a 6 CINEMATOGRAPHER a Regent Street, for a short season. We congratulate Mr. Ponting on the presentation of the film in its new form, as in spite of the fact that it was made in the days when cinema¬ tography was a more difficult propo¬ sition, and before super cameras and super pan. films were available, it bears comparison technically with the best travel pictures of to-day, and in many phases is better. Pictorially it is a great achievement, while historically it is a record for all time. Every reader who has the opportunity of seeing the film should endeavour to do so, even those who do not care for “ ordinary ” films. The Charm of Realism. By an odd chance, in a Blooms¬ bury teashop, we came upon a book of photographs which a previous visitor had left on the table. They happened to be photographs of a part of the country which we knew well, and delighted in, and although there was nothing very distinctive about the photographs themselves, they gave us real pleasure. Every one of them opened a gate of memory, and although they were “only photographs,” there was no jarring, the thing was as we had known it, every twist of the lane, every crocket of the steeple. In the same street of Bloomsbury, in the window of a print-seller’s shop, we saw a coloured sketch of one of the beautiful buildings which had fascinated us in the book of photographs. It was marked 18s. 6d., but although in many ways a very happy compo¬ sition, it was wrong in one or two particulars. The tower did not quite go up like that, nor did the river bend at that particular point. We may say what we like about the manipulation and suppression of detail — which is not unknown in photography itself — but there is a really great charm and asset in having the thing as it is. The A mateur Photographer ” E XPOSURE T ABLE — AugUSt 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/n is used. For f/16 give four times the exposure. For f/5.6 give half. From 8 to 10 a.m. or from 2 to 4 p.m., give double. From 6 to 8 a.m. or from 4 to 6 p.m., give three or four times. From 5 to 6 a.m. or 6 to 8 p.m., about four times these exposures will be required. N.B. — The times given above are by “ sun 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." Subject. Ordinary. Medium.
