I've got home, I've got the book and I've got some time. There are formulae for negative, reversal positive, non reversal positive all both in still and cine versions, and paper processes. There are also procedures and formulae for replenishment but I think I'll omit them as they are of limited use nowadays.

With what should I start?

Is there any way to make decent tables in apug posts?

All color orwo formulae I have use T22 alias TSS alias N,N-Diethyl-p-phenylenediamine Sulfate which I believe is CD-1, CAS 6283-63-2. Please correct me if I got it wrong.

No APUG doesn't use tables, which is a pain.

The British Journal of Photography, published formulae for Orwo materials for some years, along with formulae for Agfa, Gevaert, Ferrania, Telko, Adox etc all of which were based loosely on the Agfa processes.

Yes T22 is CD-1.

I recommend you post the formulas in the (there was a url link here which no longer exists) which includes sub-areas for film developers, stop baths, etc. Unfortunately, there's no area for "complete color processes" or the like, but adding cross-references to the different components should get the job done. The articles area does support comments from others, so in practice it's much like making a forum post, but it'll be easier for people to find the information in the future -- at least, for anybody who realizes there's an articles area with formulas and thinks to check it!

Now don't be sarcastic - the Articles area is under reconstruction, Sean promised it would be finished in a couple of weeks . . . . . . . rather a long time ago. He also said tables would be possible.

There was no sarcasm intended on my part. I've seen recent posts to the articles section, so it's active right now, AFAIK.

Please give me an example of these non-reversal positive formulas and films
