Solarol Developer for Black & White Paper

Solarol the solarizing developer provides a new dimension of image control through the use of the Sabattier effect, commonly called "solarization".

The effect is produced by re-exposing the print to white light while it is in the developer. With other developers, this procedure gives a dark, muddy picture, but with Solarol, contrast is maintained, sharp edge effects appear, and a beautiful surreal image is obtained.

The tray life of Solarol equals that of the best of print developers, and it keeps for over two months in a well stopped bottle. With extended use, its developing action becomes slower, but its solarizing ability actually improves.

It should be discarded when it is too exhausted to produce a good black with two minutes of development.
