Another low contrast developer candidate is C-41 color developer.

Cheap enough to buy, no need to make your own. Formula is:

Water 800 ml
Potassium carbonate 38 g
Sodium sulfite 4.7 g
Potassium bromide 1.5 g
Kodak anti-cal (optional) 1 g
Hydroxylamine sulfate 3.9 g
CD4 5.9 g
Potassium iodide 1 mg
Acetic Acid to pH 10.00
Water to make 1 liter

Well, at least it's not YAMQ.
