Interesting difference in result. I certainly find the second one (warmer developer) better.
There is so much to this (as for everything!) Your practical research is so valuable to those interested in this technique, and interesting to many others as well.
Thanks.
Best regards,
Doug

Chris,
I too like the second version better as the cloud is more open to enjoyment.
But what did you mean by the adjective “warmer”? Did you mean “color temperature” or perhaps thermal temperature?

Hi, Asher,
I believe he is referring to the temperature of the developer solution. In one case it was at "room temperature"; in the other, at 130° F.

Doug is correct. !30 F for the Potassium Oxalate developer. It warms it up significantly but also gives a greater tonal separation.

Am impressed in both of you, you Chris for taking this extra step and Doug for his bulldog like determination to discover how things work!

Chris,
How much of this cooking recipes are standard knowledge delivered with the prepared paper? Do they include a set of options for you to try?

Nothing like that. I just read what Chris wrote here.

Fabulous! Shows difference in ranking data. I was only interested in the image as it was spectacular.
You are detail oriented and likely use the titles more than I do in processing the image. So your methodology gave you an advantage, but I spent more time happy, LOL!

None...paper is nor pre-prepared. There are books to guide you but the best information comes from the chemical/paper supplier, Bostick & Sullivan: https://www.bostick-sullivan.com/
They are located in anta Fe NM and offer workshops, private lessons and the like. Great folks!
