SNAPSHOTTING IN GASLIGHT.

To take a photograph of a public meeting, or a theatrical performance, at night has hitherto involved a goed deal of difficulty, necessitating the use of fiarii.ights; but the new lens just invented by Dr Gnm, aud exhibited by him to the Camera Club, in London, promises to render photography under the ordinary conditions of artilicial illumination as simple as in daylight. Dr tirun s new lens dilfers from the ordinary patterns by being composed in part of a ■ £ ™ e^‘utn - .By su.tably combining this with the enclosing glass lenses an enoimous ught-grasping power is attained, the lenses working at ihe surprising aperture of f.1.4, and even of 1.0.5. Tnis allows a scene in a stage play to be “ snapshotted ” as easily as a landscape, and without any spec al arrangement of the ilumination or of the actors. Moreover, the lens has a great depth of focus, depicting the actors in the extreme front of the stage and the scenery at the back with perfect sharpness. So rapid is the new lens that Dr Gnm has attempted to secure kinematograph view’s of a play. The results, though by no means first-class, were good enourh to show that complete success will probably fol'ow on a little more experimentin'?. Dr GmS’s invention should be a godsend to the illustrated papers.
