It would be funny to include a QR code on the print with all the details.

Not to be scolding, but to appreciate. The analog process depends on a lot of factors coming together in an amazing coincidence that it works at all, that the artist had a hand in it all, and the result (constrained by self-imposed restrictions) is beautiful.

It is noteworthy that what used to be inconceivable (large PT/PD from miniature formats) (PT/PD from negatives that were not developed to long scale) is now possible. True it was possible to produce suitable internegatives - but the masters used original camera negatives and processed them (pretty much by feel) to fit the print.
