Alright, here's the list so far:
Shangeye, to answer your question, and I'm sure some of the others, I'm going to copy here what mikeg wrote in Round 2:
1. This is about sharing what can be done in lith printing with the emphasis on the process and not on the value of the prints themselves. I plan on sending my best attempts and I'm sure everyone else will do the same.
2. Print size and presentation will not have any requirements. Prints may be on fibre or RC paper. They may be unmounted, mounted, and/or matted. It's up to you.
3. The print may be straight lith or bleach and redevelopment in lith
4. The addition of explanatory notes is optional, but the recipients may appreciate an explanation of the process, such as paper type, lith developer, dilutions etc.
5. The exchange is open to anyone who wants to print in lith.
6. This is an international exchange, so be prepared to send your prints anywhere in the world.
7. Everyone will be divided into groups of 3 or 4 people. So the maximum number of prints you will have to send is 3.
Of course, this is open to discussion, but my feeling is that most of the veteran participants like the style that's been set up. Please correct me if I'm wrong.
