Does anyone recollect them? I bought a book on darkroom techniques in an used book store. The book came with a vinil bag that contained a 5x7 RC print and an original FP4 (not plus) negative in a small glassine sleeve. There is also additional info given which reveals that the film was developed in ID11 stock, the photo was taken with a motorised Nikon camera and printed on Ilfospeed Multigrade glossy paper. The photo is of English countryside with a house and a human figure (a fisherman) by a lake. It's purpose I guess was to show novice photographers how a properly exposed and developed negative looks like.
What I know and somehow is related to it are the editions of the "Agfacolor" book by Berger which all contain a print on Agfacolor paper.
I guess I somewhere got a technical photo-book containing a positive transparency.
But a book containing a negative as educational sample is new to me.
However one dustcover for the Berger book bears a photograph of a woman doing her make up in front of a mirror. One of the two images of her is positive the other negative. An intriguing photo-montage.
Maybe Simon Galley remembers when Ilford issued these reference negatives? Were they supplied on special request only? I would really like to know more about it. Meanwhile I will look for it and show it here.
It's quite probable Ilford ran similar promotions in the US, I know they gave prints of images by well known photographers printed on Ilford paper with a French magazine, I have a Robert Doisneau print from my last visit to Paris (there were a few different images).
I too have one of the promotional prints from - I think - William Klein, printed on Agfa paper, that came with a French magazine PHOTO about ten years ago. But the reference negative was aimed at beginners, so that they would know how a good negative and print look like. What is surprising is that the small RC print survived for at least 30 years with no signs of deterioration in a PVC sleeve.
I have a Kodak Colour Dataguide from 1968 and another from 1974 which both came with a negative [Ektacolor Professional S - C22 Process] and an accompanying 2x3 inch print. They were definitely part and parcel of the original publication as the envelope's edge is incorporated into the spiral binding.
I really wish I'd been in the right place at the right time to be on the receiving end of some of those prints in the French magazines that Ian mentioned.
