This print was produced entirely by hand by me using a black and white film and time honored processes in a traditional darkroom. Materials and processes are of the highest quality currently available.
The photograph was printed on a double-weight fiber based silver gelatin paper by projecting an image from the negative, then processed through multiple chemical baths to reveal the image, then washed and protected. The expected life span of the print is in excess of 100 years when kept in a protected environment. Please handle the print with care as oil from your hand can affect its future condition. Having it framed in archival quality material and UV protected glass or in an archival quality folder is the best way to display or store this photograph.
Thank you for your reply. Some are, some aren't. When they aren't, they are, at minimum, treated in StabAG. (Sitan)
I've tried very short Selenium toning. I didn't appreciate the slight (although very slight) density change especially in highlight. Toning isn't an absolute requirement for being "archival" is it? (or is it...?)
I would indicate to the recipient that they have framing done by a framer that is familiar with photographic archival materials and if they were going some other route that they request acid free materials (especially in humid Florida) and the emulsion should not come in contact with the frame glass. Once they purchase your print it's theirs and what you say is just a disclaimer and a suggested way to preserve the print.
