LIGHTING Brilliant sunlight Weak sunlight or bright diffused Diffused or slightly cloudy Dull Gloomy, or very dull HIS table shows the approximate aperture to be used for all classes of subjects in varying conditions of light. Film speed is also taken into account, cine films having been classified as follows :— Group A Group B Group C Gevaert Ortho Agfa Ortho Agfa Novopan Reversal and Reversal Reversal Negative Agfa Pan.

Stop required—f/7 The table is compiled for exposures between the hours of 10 a.m. and 3 p.m. (G.M.T.); from 8 to 10 a.m., and from 3 to 5 p.m. (G.M.T.), the diaphragm must be opened a half to one stop wider. Where the indicated aperture is not engraved on the diaphragm it is sufficient to estimate the setting between two engraved figures, remembering that the divisions get smaller as the aperture gets smaller, and that f/8 (for example) would lie almost dead central between the f/7 and f/10 markings. Telephoto on the CineEight The Cine-Kodak ‘“‘ Eight’’ has made itself felt already as a serious contribution to the resources of amateur cinematography. Kodak now announce twe developments which will give this little pocket cine-camera an even wider appeal to the worker who is not content with a one-lens “ cinesnapshot ”’ camera. Owners of the f/1.9 model can now obtain, for interchangeable use, a Dallmeyer f/4 Telephoto lens of 1% inch focal length for £4 4s., plus half-a-guinea for the adapting and fitting. The other development concerns the Kodascope Eight (Model 30)— the nine-guinea projector for the “Fight”? films. Kodak are now listing a Dallmeyer Wide Angle C § § § § § § Ny § § § § § § § § § O A SUBJECTS Promenades ; camp picnic scenes ; taking off’’; track motor racing; open scenes at racecourses, sports meetagricultural shows, fairs, parks, zoos, Door oor ro po ooo O 5 Compiled by { {HAROLD B.

Where the exposure is known to be different (usually 1/50th second) or where the camera is operated at a speed other than 14 or 16 pictures per second, the aperture must be varied accordingly. It should be noted that the times given are Greenwich Mean and not Daylight Saving and adjustment must be made accordingly. Thus, 8 to 10 a.m. G.M.T. would, of course, be 9 to 11 a.m. Willett time, and so on. Projection lens of their f/1.8 series PRED EArOSURE CHARTS World ’’ Exposure Chart.

This sells at two guineas and is made to be interchangeable with the ordinary projection lens. As _ experienced workers know, the wide-angle lens gives a larger picture on the screen than the standard lens when a short throw is used—a quality which is helpful to the success of pictures shown in a small room with a necessarily short throw, in fact, those of us who show our 16mm. films away from home make a point of taking with us whenever we go out to give a show, not only our standard projection lens but a_ wide-angle one in addition, in case we find ourselves committed to project the films in a small room. Messrs. Dallmeyer tell me that they have also begun to supply their Popular Telephoto lens, with an aperture of f/4 in the three-inch focal length for use on the CineKodak Eight.
