By adding Zonal Pro HQ Warmtone to my Bromophen/glycin I can get the
green out of Agfa Multicontrast Classic. Without it, no amount of
selenium tone will rid me of this green cast. It will split-tone
weirdly, before a good color results. For some reason, the Zonal-Pro,
not only starts out a little warmer, it also allows a good amount of
toning to occur. The final color is excellent.

Can anyone tell me what chemistry is at work in the Zonal-Pro? Can I
add something to my regular developer to duplicate this effect, without
having to spring for the costly Zonal-Pro? Is there an Agfa user out
there who does not have the green problem? What developer are you
using? The only warm-tone developer I haven't tried is the one I should
obviously try and that is the Neutol-WA. I thought I had ordered it,
but mistakenly got the Neutol, sans WA. But I am still curious why the
Zonal-Pro is so successful changing the paper color, as from what I
understand developers have modest color changing abilities. Thanks, KAS
