How about:

"Traditionally and optically printed on a finest quality photographic paper coated with silver gelatin and processed in a darkroom with a bunch of trays full of chemicals for those who care, know the difference, and willing to pay for the privilege of owning the finest but not quite the finest because these are RC rather than FB in which case you really can't afford it"?

At the end, no one will care, and as long as they sell, probably you shouldn't either... (yeah, but we do... grrr....) It is becoming painfully aware to me, those things WE care so dearly, no one else does... and we probably do all these just to satisfy our own purpose.

grrrr.... (as I stress over the color of mat material....)
grrrr.....
