There is no text or anything else in this post, other than a full stop...?...

With over 50 views so far, am I the only one to presume there should have been something to see, or am I the only one seeing a blank area?

Don't overlook the full stop/period! It is very important, way better than a boring comma.

hey kevin
best way i have found is to expose normally,
develop > citric acid stop > dollar store peroxide with a squirt of 10% citric acid added in water rinse
then rust-out as a chemical fog/developer/fix wrapped into one.
works pretty well !

good luck !

Thanks forthe reply jnantz. I removed my post because I found there is already information on the subject. But I am interested in your technique. Do not know about rust-out, that is new to me. So the rust-out foggs, develops and fixes all at once? What % of rust-out or use full strength? Just 3% peroxide for bleach? This sounds really good.

hi kevin

i always mis-say the name, its iron out not rust out!
here is a thread on this sort of reversal technique, DonF has info on the rust out
i think its a teaspoon /L .. i haven't done it in a while but i referred to his experience
https://www.photrio.com/forum/threads/reversal-print-processing-video-new-approach.153447/

i had a lot of trouble finding the right concentration of things, i used storebought peroxide instead of the
stuff that is super concentrated its cheep and works well, and is less dangerous and i found that it was about 2 squirts of 10%
citric acid did trick for me but it might be different for you, it clears the paper pretty fast. if you don't want to use the iron out you can do the traditional
fog the paper with room or sunlight, and redevelop/stop+fix it the way most people do ... i don't like the smell of the iron out so
haven't done it in a while ..

have fun!

OK, this is what I had posted then removed thinking it was redundant since I found other material on the subject. Reversal
printing is new to me so I am having fun with it. There seem to be several ways of doing this process, my bleach solution is copper sulfate and potassium bromide. So far it has worked only with Arista EDU grade 2 paper, Ilford MG does not behave the same so I ordered 35% HP.

Thanks. I have some HP on order and will try it with Ilford MG to see how it compairs to what I have been using.
