We mainly used Agfa's Neutol NE, that's to say, the "normal" one, not the one to produce warm tones. It comes as a 10x liquid concentrate. I believe after Agfa's bankruptcy some smaller company did buy the license for that developer. So it has become available again.Ed Wesly wrote:It was interesting to hear that you used a photo paper developer on the holo plates. Could you give us some details?
A while ago, on some photo website I picked up the formula of the 10x concentrate:
potassium sulfite.........312g
potassium hydroxide......15g
potassium carbonate.....90g
hydroquinone................45g
phenidone....................1.5g
EDTA..............................8g
potassium bromide........10g
water..............................1L
I assume the "EDTA" actually should read Na4EDTA. It can be skipped when using deionized water.
For PFG-03 film I used 1L Neutol working solution + 5-10g boric acid.
Interesting. That brings up a lot of memories. We systematically tested all the Kodak, Agfa and Ilford products available in the early 1980s. Regarding Kodak we went through from D-8 to D-82. We were surprised to learn that paper developers seemed to perform better than all the fine grain developers.I have used Kodak Dektol, a paper developer on Agfa 8E75HD plates, however instead of the recommended 2 parts water to one part of developer to make a working strength solution, I used two parts developer and one part water, because when you compare the formula of Kodak D-19 to the closest published formula to Dektol, Kodak's D-72, this dilution brings the concentration of metol and hydroquinone to the same strength as D-19! There is a bit more sulfite in the paper developer, about the same on the alkali, sodium carbonate, but it worked pretty much the same as D-19.
