Divided PQ paper developers

[varjag]

Anyone has a recipe of a divided phenidone-based paper developer they're willing to share? So far I've been using an ordinary metol developer but as the weather is getting hotter am having a hard time fixing the time/temperature variable of the process. There is a split metol-based dev recipe in the chemistry section here, but I would like to try phenidone for once.

Maine-iac's post in the Apug Chemical Recipes talks about recipes for both MQ and PQ.

You could easily split ID-78 (a popular PQ paper developer).

ID-78 Warm Tone paper developer

To split ID-78:
Take the 62 grams of anhydrous Sodium Carbonate out of the recipe to make the “A” bath.

Dissolve the 62 grams of anhydrous Sodium Carbonate in a liter of water to make the “B” bath.

Have fun!
