The chemistry to make black and white films with panchromatic emulsions of 100 ISO were developed in the late 1930’s by Agfa in Germany.
What our predecessors would have made of the Nikon D4 capable of 200 400 ISO I don’t quite know.
This picture “evening Stroll” was taken at 50 ISO the Slowest my camera will go without Neutral Density filters. There I was happily taking picture of ou of focus Daisy’s in front of a fence and a tree and this pair of legs walked in to my picture. Thank you very much I like that.
A big welcome to all the new followers of my little blog.
