PMK and Zone System

[jean_bernard_roux]

I'm looking for N, N-1 and N+1 times for PMK developer with usual films as Tri-X, Plus-X, Tmax 100 and 400, Ilford FP4+ and HP5+, Bergger BPF 200 (with the right iso rating).

 

<p>

 

 

Is there somebody who have tried this and get informations on results (accutance, values range etc...)

 

<p>

 

Thanks

Try www.unblinkingeye.com. You might have received quicker (and more)

responses had you filed your question on the film and developing

forum.

You need to calibrate the times to your system for optimum results.

You should be calibrating your system anyway.

Gordon Hutchings, the inventor of PMK developer, published this

information in his book "The Book Of Pyro". The book should be

available from Photographer's Formulary, Calumet, and the author

usually has an ad for it in "View Camera" magazine. The book is a

requirement for anyone trying this developer.

The book of pyro is the source you need. I use PMK for all my

processing. I shoot HP5+ at 400 and process for 13 minutes.

I develop in tubes and have recently posted some PMK times for FP4. http://home.att.net/~shipale/
