Amateur Photographer & Cinematographer (1937)

December 15th, 1937 N EWS AND REVIEWS ITEMS OF GENERAL INTEREST FROM ALL QUARTERS. Part II of the Modern Encyclopedia of Photography, published last week, is devoted entirely to the subject of Developing, Developers and Desensitisers. This number is a very complete instructional handbook and guide to these matters and contains 14 separate articles covering every phase of the subject in addition to a special folding chart of no developing formulae. Many illustrations are included and the whole is a remarkable shillingsworth. Each weekly part of the Modern Encyclo¬ pedia of Photography is obtainable at all bookstalls and booksellers or direct from the Amalgamated Press Ltd., The Fleetway House, Farringdon Street, E.C.4. Readers of " The A.P.” who have not yet secured copies should do so without delay. The work will be completed in twenty-six parts. We hear that the Grand Prix of the International Paris Exhibition, 1937, has been awarded to the Robot minia¬ ture camera. Kodak Ltd. inform us that they are always interested to receive good photo¬ graphs taken by amateur photographers, and if the photographs are attractive enough they will buy them for use as specimens. The only stipulation is that the negatives must be made on Kodak film and it is desirable, but not necessary, that they should have been taken with a Kodak camera. Many readers of “ The A.P.” with suitable prints will doubtless like to take advantage of this offer. They shou'd submit photographs in the first instance to A. P. Hynds, Dept. 46, Kodak Ltd., Kingsway, London, W.C.2. The Metrogas Photographic Society, South Metropolitan Gas Company, 709, Old Kent Road, S.E.15, informs us that Mr. A. G.

A new Society known as the Suttonin-Ashfield and District Photographic Society has recently been formed, of which the membership is increasing rapidly. Meetings are held every Mon¬ day night at 7.30 in the Toe H. Rooms, Low Street, Sutton-in-Ashfield, to which new members will be welcomed. The Hon. Secretary, Mr. S. C. Huffen, 11, Pepper Street, Sutton-in-Ashfield, Notts, will be pleased to hear from any amateur photographers in the district who are interested. A number of keen amateur photo¬ graphers have banded together, under the temporary secretaryship of Mr. F. Hart, 14, Barleycroft Road, Welwyn Garden City, to form a new club known as The Welwyn Garden City Photo¬ graphic Society. The Society is in¬ tending to seek affiliation to the East Anglian Federation, and meetings will be held on Wednesday evenings through¬ out the winter. Mr. Hart will be glad to hear from intending members if they will write to him at the above address. The King’s Heath and District Photo¬ graphic Society inform us that their membership during the past twelve months has shown a steady increase, but they are still anxious to admit new members, especially beginners, who will be welcomed and assisted by the more advanced workers of the Club. The Hon. Secretary is Mr. L. P. Lowenthal, Wayside, 37, Hazelhurst Road, King’s Heath, Birmingham, 14, to whom all communications should be addressed. Those who like to keep their photo¬ graphs within easy reach will be inter¬ ested in the Ensign Library Albums and Book Boxes, which are finished to look like ordinary books and can be placed inconspicuously among them on any bookshelf.

Sizes run from 3^ x 2% to whole-plate, the prices ranging from is. to is. gd, and this method of keeping prints is especially suitable for enlargements. In addition to these novelties, the Ensign catalogue of albums contains descriptions and illustrations of more conventional al¬ bums in all sizes and types, including the Glen jo slip-in album, in which the prints are held in a new and very con¬ venient way. A copy of this catalogue will be sent post free on application to Messrs. Ensign Ltd., 88-89, High Holborn, London, W.C. 1. An Empire Wild Life Photographic Competition is being organised by the Field as part of the Sporting Exhibition at the Imperial Institute to be held in January, 1938.

Mr. Fritz Borst, Schonbach b. Eger, Czechoslovakia, has again been success¬ ful in winning the Wallace Heaton weekly award of one guinea. His print “ Fly bird, fly ! ” was adjudged the prize winner in the first of the “ Speed and Action ” competitions, full particu¬ lars of which will be found in the adver¬ tisement pages in this issue. FACTS and FORMULA /~|NE or more items of practical value to the amateur photographer are given under this heading in every issue. The series from No. 1 to 61 included all standard chemical and optical formulae and practical instructions, etc., for the principal processes.
