Photographers’ Formulary D-19 Developer Substitute


Photographers’ Formulary D-19 Substitute is a kit of individual chemicals that must be mixed to create the developer substitute. It is an excellent replacement for Kodak’s now discontinued D-19 developer. It is a high-contrast developer originally designed for use with x-rays. Mostly used for scientific applications with spectroscopic films and plates, high resolution plates and films like Tech Pan and high speed Infrared film. Many now also use it to develop Super 8 or 16mm film black and white reversal film.
