I'm interested in two-bath developers like D-23 and Pyrocat HD two-bath for their compensating development.
Is it possible to change the rate at which development takes place (i.e. contrast control), the rate at which silver halides exposed to sufficient light are reduced to elemental silver, by changing the dilutions of one, the other, or both baths?
I would think it is possible.
If so, is it better to reduce or increase the concentration of the reducing agent (bath 1) or better to reduce or increase the concentration of the alkali? (bath 2)
Thanks,
