Very useful accessory for pre-flashing photographic papers.
The Paper Flasher makes it very easy to pre-flash papers, without having to remove the negative from the holder (risk of camera shake) or having to use a second enlarger with a second feeder.
Placed next to the lens, the very weak light source is controlled by an electronic control module, powered by a 9V battery. This module-timer incorporates a test strip function to determine the pre-flash time required to see the first grey of the paper appear.
Exposure times range from 1 to 84 seconds.
It is possible to pre-flash only a part of the paper. Indeed, it is possible to project the image in inactinic mode onto the paper and thus visualise the areas to be pre-flashed.
