Hi Frank, To answer your questions.
1. There could be a great many, or as few as 2 in the exchange, but you only have to send a print (or prints) to one other person so postage anywhere on the globe is manageable.
2. Cyanotype is good. Inkjet is not so good. Basically we try to hone our skills in the "wet" darkroom and share our best/proudest prints with others.
Hope this helps you.
Sorry, I did not see your previous answer before answering to Frank.
From my point of view, a hand-coloured inkjet print is a unique hand crafted picture, based on a photographic process. So I would accept it. The "Alt" portion includes a lo of different processes, most of which use digital negatives these days. So a contact copy from a digital negative (although made in a wet process) can have a strong digital component, like contrast adjustment.
On the other side, I do see you argument that was have always made the exchange based on a wet Darkroom process.
What do you think about the following:
If a participant wants to send a hand-coloured inkjet print, please inform so. If any participant does not want to receive a hand-coloured inkjet print, please also state so. I will arrange the exchange accordingly.
Can we agree on that?
