I usually say "Gelatin Silver Print" or "Toned Gelatin Silver Print" when I enter work in shows. (I put gelatin first as I suspect there's more of that than there is silver.) Those long lines about "traditional ... blah blah blah" would be fine in an artist's statement, but in most of the shows I enter the entry form line for medium is about an inch long!

Occasionally I am asked by visitors to the shows what that means, in which case I explain "I use a darkroom."
