I've been doing a lot of this, just developed some Verichrome that expired in 1947 with good results.

B&W is much easier than color films though.

You need to use a FAST developer to reduce fog from my limited trial runs, so find a developer that has fast times like Ilfsol 3 which does most films for 5 minutes. Long developers seem to introduce fog.

I've been collecting info on older color films and I'm putting together the original developers from scratch. I think that's much better ultimately. It's just an arduous process.

Examples of "success"



If you find the full C-22 process chemistry WITH actual measurements, please pass it along.
