I just mixed up a batch of Pyrocat HD (Sandy King formula) and got some horrific results. I've used this formula with great success in the past. I'm suspecting that the chemicals are not fully dissolved. This example is an unexposed section of film. The film is Ilford Delta 100. The frames that were exposed look great with the exception of this same nastiness. Curious to know if anyone has experienced this. I will be having a real close look the A and B mixes to be sure that the chems are fully dissolved.
