Pyrocat vs Exactol Lux vs Prescysol EF?

[m_liddell]

What are the differences between Pyrocat, Exactol Lux, Prescysol EF?

So far I have used Pyrocat HD and Exactol Lux, but not made enough prints or tested them comparatively to make a judgement. I've stuck to Exactol Lux since you can get it in the UK and it seems to keep better. The dev times are different (11mins against 8mins for acros) but on the face of it the results seem similar.

Has anyone properly compared these three developers?

I am not aware of any well designed and controlled comparative studies of these two developers.

In my experience the Sandy King's Pyrocat-HD "A" (mixed in water) stock solution keeps for months.

Sandy King recommends that the Pyrocat-HD working solution be used as a one-shot, and that is the way I use it.

It is also my experience that the Pyrocat-HD "A" stock solution mixed in Propylene Glycol keeps for years with no change in activity.

Same for Pyrocat MC or Pyrocat PC.
