EXCELLENT Photographs in Colour are obtained with our smaller lens filter Outfits, complete from 25/-; but for general work, Landscapes in changing light, Portraiture or Photomicrography where rapid exposures in succession are necessary, the Repeating Back with Colour Filters is recommended as the best all round appliance.

It may be attached to any 4, or whole-plate camera or glass plate Kodak, by means of a panel cut to correspond and interchangeable with the ordinary dark slide. This does not in any way interfere with the use of the camera for ordinary work. The three Colour Filters are held in a frame, clipped in front of the double dark slide which carries the two plates, each large enough to record the three negatives side by side, when the slide is pushed past the opening in the outer case.
