Re: Acid type Rapid Fixers - request recommendation

Any rapid-fixer from a renowned manufacturer will do, eg; Ilford Hypam/Rapid Fixer, or Kodak equivalent.

The Wellington Photographic Handbook

Here is a link to a handbook which contains a Borax MQ developer formula that predates Kodak D-76 and it's many copies and variants.
Those who like to experiment with photographic developers may find this publication of interest.

Re: Adox FX-39

When is the product to be available? I don't see it on the Adox web site. The Spur Acurol-N developer is available from this site. http://www.macodirect.de/spur-acurol-250ml-p-2510.html?language=en&osCsid=782e362bc991eab30a270f24c72cd642 I still don't know if it is a Rodinal type or not, as I have ...

Re: Adox FX-39

I'm not sure to be honest. In post #3 in this thread, the author reckons that sharpness is better than Rodinal with tighter grain. I would have thought better resolution too. http://www.apug.org/forums/forum37/118856-my-sharpest-ever-negs.html It would be good to see how it compares with FX-39. "Sh...

Re: Adox FX-39

Perhaps Adox will market this product better than Paterson. You may also find the Spur range of developers of interest as well. These like the Paterson developers appear to be somewhat more specialized than the regular general use fine-grain developers like D-76/ID-11. Have a look at Bruce Robbins s...

Re: Rollie IR400 Reciprocity

It's something you will have to experiment with and bracket the exposures to find out.
I have never heard of the developer. Sorry if that's not much help.

Adox FX-39

Adox have announced that they will continue to make FX-39 after Paterson Ltd discontinued their photo-chemical products.

Re: Finally had it with Pyro.

Kenny I am a scientist not a photographer. I am a manufacturer not a experimenter. What scientific information would you like to know about your "brew?" I don't need the "brew" because I would rather look at a 1 liter mix and a 21 step wedge of the curve produced on a TriX or HP5 film when processe...

Re: Finally had it with Pyro.

Ilford's own developers are very good from the tried and trusted ID-11 (D-76), Microphen and their excellent DD-X. For optimum image resolution and quality if a small loss of film speed can be acepted, try Perceptol diluted 1+1. For further information, download the fact-sheets from Ilford's own web...

Re: Which "Salt or Pot ash" to use

Keith, I am impressed by Damon's work, for a person who has not been at this for very long. His use of technical pan and forma 200 with PMK, is good work. And even more so with his floral pictures. Lowell, thanks for the information on the preservatives. I was thinking of conducting tests with all ...

Re: Which "Salt or Pot ash" to use

Hello There is a considerable difference between the two, Sodium or Potassium Meta bisulfite and Sodium sulfite. The first two are interchangeable with some adjustment for molecular weight difference and the "salt" is a preservative or oxygen scavenger. Lowell Huff Clayton Chemical Lowell, I have s...

Look up the formula for Pyrocat-P and decide from there.

Re: New Ilford Papers.

I wonder if this was necessitated by Adox' successful mcp and mcc papers that were introduced some years ago. Jim I believe that the papers were designed the way they are due to customer feedback.
