PHOTOGRAPHIC SOCIETY

The fortnightly meeting of the Dunedin Photographic Society attracted an excellent attendance. Before introducing the lecturer for the evening, the Chairman (Mr T. A, Dawson) announced the results of the New Zealand interclub photographic competition held this year in Invercargill. Eight clubs competed, the results being as follows: —Invercargill 1, Wellington Camera Circle 2, Dunedip 3, Wellington Camera Club 4, Auckland 5, Christchurch 6, Timaru 7, Wairarapa 8. The pictures will bo exhibited here early in August. The lecturer for the evening, Mr W. B. Seymour, gave a most interesting lecture and demonstration on that very important branch of photography, sepia toning. The lecturer explained the chemical reactions which occur during the development and toning of bromide paper, and, by demonstration, showed that by taking advantage of a diluted bleaching bath, together with variation of the immersion time in the bleach, different tones of sepia, ranging from brown-black to chocolate, may be obtained. Referring to the sickly yellow tones so often obtained by amateurs, Mr Seymour demonstrated the cause of these failures, and, to illustrate his remarks, made a number of failures and then showed methods of overcoming the difficulties. Mr Seymour also distributed written formulas, as used in his demonstration, and at the conclusion of his lecture was accorded a hearty vote of thanks. The Social Committee then took charge, and supper was dispensed.
