I have used heavily expired film for speculative and possibly expressive effects. Here is an example:
Past Imperfect #7
Gelatin-silver photograph on Ultrafine Silver Eagle VC FB photographic paper, image size 16.4cm X 21.3cm, from a 4x5 Tri-X Pan Professional negative
exposed in a Tachihara 45GF double extension field view camera fitted with a home-made 150mm f4 Wollaston Meniscus soft-focus lens and a #25 red filter.
My photographer friend died after a long long illness and some of his equipment passed into my hands.
There were many film holders that he had loaded with Tri-X fifteen years previously but could not expose.
The film had corroded through the passage of years but I took it to those places where we had previously walked with our cameras.
I tried to make this Past Imperfect exposure as a kind of meditation on time and loss.
