An award-winning and environmentally friendly B&W film developer, 510 Pyro is one of the more modern pyro developers, that was invented by Jay DeFehr. It offers exceptional fine grain, sharpness, more than 6 years shelf life, maximum image stain and minimal general stain and is suitable for rotary processors too.

The stain offered by this developer gives extraordinary shadow recovery in direct digitisation of negatives; easy enlarging and incredible highlight separation in darkroom silver gelatine printing and more density for highlights when using UV based alt process printing methods. It protects film from damage through tanning the emulsion and uniquely gives negatives that are optimised for scanning, silver gelatine and UV printing processes with the same or similiar development time.

By using extremely dilute working solutions – 1:100 to 1:500, this makes this developer also extremely economical!
