Apologies if I’ve cut across the ideas of others. I wrote this before reading the more recent posts. Rather than rewrite it I’ll post it as first written.
Mike, one way of going about it might be to have a series of occasional posts interleaved with the normal ones, entitled “Restorers’ Notes” or some such, perhaps with a subtitle describing the main thing discussed. Examples might include such things as:
1. An interesting/unusual/difficult picture is posted. A restorer starts a topic, “Restorer’s Notes: Scanner Stripes” to begin a discussion on the picture, techniques used etc - with links to and from the particular photo post which gave rise to the discussion.
2. A restorer starts using a different program or technique, not necessarily related to a recent photo. They start a topic, “Restorers’ Notes: Fourier Filters”, or “Restorers’ Notes: GIMP” to discuss their successful (or otherwise) experience with the new thing.
I think with something like this it would operate just like a normal post: if you are sufficiently interested in the topic you put your two bob’s worth in, if not you simply don’t. But the name of the post alerts restorers that they are the intended audience.
Perhaps the Moderator has some ideas on this: whether something has been tried before, whether they can see any problems, or whether they might have any ideas about the best form for it.
Cheers,
Peter
