Amateur Photographer & Cinematographer (1933)

July 5th, 1933 The AMATEUR PHOTOGRAPHER 6 CINEMATOGRAPHER a of ruinous experiment, he died a more or less disappointed man. Even for long years after his death his genius was unrecognised, and when in 1855 there was a suggestion in the municipal council of Chalon that a statue should be raised to his memory, it was turned down on the ground that it was not certain whether Niepce did invent photo¬ graphy after all. (A statue was, in fact, erected about a quarter of a century later.) Three hundred and fifty sat down at the banquet, in¬ cluding twenty-six of Niepce’s des¬ cendants, thirteen of whom bore his name. In the course of the speeches, which were broadcast, the mayor paid tribute to Niepce’s patient labours and determination, his splendid disinterestedness, and the greatness of his discovery, which reflected honour upon the French people and French science. Messages were read from photographic bodies in seven European countries, and then the principal speech was made by the Minister for Education, who described Niepce as a great re¬ volutionary. “ The great technician is more of a revolutionary than he who upturns the political founda¬ tions.” This was the only speaker, apparently, to mention Daguerre, and, as was perhaps inevitable on such an occasion, the comparison was unfavourable. It is natural also, when lauding a man, to extend the laudation to his country, and thus some of the speakers perhaps claimed too much for France — excusable enough under such aus¬ pices — and for French achievements in the photographic field. To France was ascribed the invention, not only of photography, but of cinemato¬ graphy, colour photography, the telegraphic transmission of photo¬ graphs, as well as innumerable advances in optics and sensitive material. But it was France’s day, and to have given the world both Niepce and Daguerre is an achieve¬ ment which justifies some shouting. The A mateur Photographer” EXPOSURE TABLE— JULY 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 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 “ summertime." Subject. Ordinary. Medium.
