The Presto is a miniature camera taking either exposures on roll-film or glass plates. It was sold with both roll-film and plate inserts that could be interchanged. The use of plates could not have been very successful as the internal baffling is not good. To re-set the shutter the camera is held upside down and the shutter released. As it is not self-capping there is a blank wheel-stop which is brought in front of the lens when re-setting the shutter. Early in its life it was used as a promotional gift. Film was advertised in lengths for either 25 or 50 exposures. In 1899 the price was 10/-. Designed by Herman Casler.
