What about adding hydroquinone? Seems I remember AA writing something
about that.

I was wondering, before getting into a personal printing session, if there's a way to boost the contrast of Ansco 115. I use it 1:4 with Forte VC Warmtone to get the warmth I like, and typically I need to use a 3.5 filter where a 1.5-2.5 would be fine with Ilford Multigrade. I'd like to be using a lower grade filter, if possible. Is there a way to chemically boost contrast in this developer? Eric Nelson
Unfortunately I think anything you do to increase contrast, such as adding carbonate, will also cool the image color.
You can try diluting less but that will also yield cooler tones. Longer development will also tend toward cooler tones.
There are some other very warm tone developers but they tend to loose a lot of paper speed and tend toward low Dmax. One of these is Ansco/Agfa 110. My memory tells me that 115 was an attempt to get similar brown-black tones with much less speed loss.
