Amateur Photographer & Cinematographer (1936)

June 3rd, 1936 fm AMATEUR PHOTOGRAPHER p 6 CINEMATOGRAPHER o the popularity of the camera among the village people. On arriving at a little station on the edge of the wolds, he got into a bus which waited there for some minutes, and from an adjoining field a country labourer was busily engaged with a little camera snapping the bus and its occupants. In this thinly popu¬ lated country, with little villages of a few hundred souls at intervals of a few miles, there seemed to be more users of the camera in propor¬ tion to the population than one would find in a big city, and the little shops which stocked photo¬ graphic supplies were also well in evidence. How cheap professional photography is, too ! Our corres¬ pondent was one of a party of forty or so of which an official group was taken on the lawn of the country house where they were staying. The photographer had come on his bicycle twenty miles for this j ob ; then he returned home to develop his plates and came back again with the prints — quite excellent prints — which he offered for sale at six¬ pence each ! And we have some¬ times been beguiled into paying half a guinea for a picture which included our distorted head at a public dinner. “ Wipes.” The cinema technicians are threat¬ ening to let loose some new horrors amongst us in the shape of “ wipes,” which is the name for the pictorial device covering the transition from one picture to another. We were told the other evening of one short film which has been produced in¬ corporating every “ wipe ” so far thought of, numbering one hundred and forty. It was called “ Cocka¬ lorum,” or some such engaging title. A common form of transition at present is a weird spiral in the centre of the screen to indicate a change of picture, but it is felt that that device is too simple to be worthy of the photographic ingenuity of film studios. At the same time, a more complicated “ wipe ” would make the onlooker more conscious of the mechanism of the thing, and that is not desired. There is general agreement that an out-of-focus “ wipe ” is better than a sharp one. The A mateur Photographer” EXPOSURE TABLE — June 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/11 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 7 p.m. give three or four times. 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 “ summer time" Subject. Ordinary.
