HF3 is a hydroquinone-free print developer that performs every bit as well as the normal print developers but totally aquatic life friendly. If you care about the environment then this is for you.
Dilutes 1+9 and its throughput and keeping is identical to normal developers.
In storage as time goes by the colour of the solution in concentrate goes to a dark orange. This is an effect of ascorbic acid (one of the ingredients) but it does not affect the performance of HF3 whatsoever.
