[Frameworks] eco-bleach effective when tinting/toning?

[robert at ontosmedia.com]

I haven't tried using eco-bleach for toning, but my understanding is 
that you need to use a re-halogenating bleach, and eco-bleach is not 
that.  It's more like the dichromate R9 bleach, and not what you need 
for conventional toning.
