  1. 510 Pyro - Film developer - 100ml

    510 Pyro - Film developer - 100ml

    £11.99

    510 Pyro is one of the new generation of staining and tanning developers, and said to be similar to pyrocat or PMK. It has very fine grain, high acutance, good stain, and extreme longevity (as a single solution). Slowly, as the developer became more widely known, a following took shape with many photographers reporting good results with both normal development, stand and semi-stand techniques. Remarkably, the developer is used at dilutions from 1+100 or 1+200 for normal development, and up to 1+500 for stand development. Learn More
