I don't have answers... just opinions.
So, I have questions:
Do photogravures from an etching press qualify as “hand coated wet prints” for the purposes of this thread?
Absolutely!
The mechanism for coating paper is somewhat different that most alt processes but one is still coating paper with ink using a "hand" process... i.e. it is not mass produced.
Do they qualify as an “alt process”?
Certainly!
Pretty much anything other than ink jet printing counts as "alt" these days. Personally, I don't consider silver gelatin "alt" but may folks do. In my view, alt processes are those where the practitioner prepares a significant portion of the final product by hand as opposed to using mass produced materials.
Again, certainly!
Historically, photogravures have been considered photographs... even fine art photographs.
I think it is worth distinguishing between photographs (images made by light impinging on a photosensitive surface; my definition, some might disagree with it) and methods for reproducing photographs.
It is also worth distinguishing between objects crafted to a high standard (fine art?) and more prosaic objects.
Most would (and have) consider images reproduced in books and magazines as photographs. Most also consider images displayed on a screen. None of these are, by most, considered fine objects.
Probably not.
I have a friend (
https://www.vaune.net/) who is an accomplished photogravure-ist. I am sure that she would help me get started down this path if I asked. Thus far, I have not been motivated to ask.
I guess that I'm too much of a chemist! ;-)
