BJP 17 March 1988-reciprocity article
Posted: Thu Sep 11, 2014 1:03 pm Etc/GMT-1+01:00
I don't suppose anybody has a copy of the British Journal of Photography dated the 17 March 1988.
There is an excellent article on reciprocity failure by Derek Keeling. I am after trying to get a copy of the article as my copy has got lost over the years.
I used the data from his article when I worked with Tmax 100 sheet film and long exposures (minutes long) in the past.
I want to use his data for colour film as I have just bought a Lee Filters Little Stopper which requires a 6 stop increase of exposure.
Can anyone help?
The BJP want £15 for an old copy which is a lot when I am only interested in a single article.
