I was surfing the APUG and some posts have made me think this. I posted an another post to Alternative section and Ian replied me with interesting information. He says this is between Carbro and Dye Imbibition. I have to search for Carbro.
I think Ian Grant's post is extremelly interesting.
Ian Grant ,
Can you shed more light to your post please , is it applicable to films also ? And why modern emulsions are not responsive ? Which factory made emulsions interesting for additional sensitizing ?
My interest is to make everything factory made and sold for few dollars , more interesting. I cant coat a film like Kodak at home. For example , making factory made emulsions softened and make them have relief with pyro developer , make inkjet printers print palladium etc are my interest areas.
Tom , Ian Grant would answer your question better.
