Amateur Photographer & Cinematographer (1933)

Tut AMATEUR PHOTOGRAPHER ta 6 CINEMATOGRAPHER o were allowed to lie idle. Perfect as are modern dry plates, several users of them met with the old-time and almost-forgotten trouble known as frilling, when the temperature was at its highest. Dot Consciousness. The pictorial photographers in¬ duced a Daniel to walk into their den the other evening in the person of Mr. A. J. Bull, whose name is associated with photo-engraving and with photography on its technical side. But his talk about the recent exhibition and about pictorialism in general was not in the least destruc¬ tive. He had a word of praise for almost all the pictures, and the others — well, they merely did not appeal to him. But there was one curious point — perhaps a psychological one — brought out. Pictorial photo¬ graphers are always striving after pattern, and it is from pattern that the photo-engraver is constantly endeavouring to escape. The news¬ papers, for example, have to use a fairly coarse screen on account of the speed at which they print, the paper they use, and so forth, but the whole aim of newspaper printing is to make the screen pattern as little obvious as possible. Mr. Bull confessed that, looking at some newspaper illus¬ trations, all he can see is the dot, whereas another person whose days are not spent in the company of etchers and engravers will say when the same picture is exhibited, “ Oh, November ist, 1933 is there a dot ? ” That, at all events, is comforting. Perhaps other people do not see in our pictures the blemish of which we are always acutely aware. Irony. The photographer often tears his hair in the search for captions. If he looks through the work just issued, “ The First World War,” which is a collection of the work of the camera during the war on every front, he will find evidence of extra¬ ordinary skill in caption writing. But, of course, in war pictures, one can employ such irony. “ Journey’s End,” ‘‘Short Days Ago We Lived,” “ And No Birds Sing ” — given the caption, the picture forms itself automatically. T.he A mateur Photographer” EXPOSURE TABLE — November 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. double these exposures. From 7 to 8 a.m. or from 4 to 5 p.m., treble them. Subject. Ordinary Plate. Medium Plate. Rapid Plate. Extra Rapid Plate.
