This “4/20” (April 20), an international day celebrating the smoking of cannabis, was made memorable by Dmitri Tcherbadji, a photographer in Vancouver, Canada. 

Dmitri, who writes for the Analog Cafe website, conducted a unique photography experiment using cannabis. He has created the world’s first film developer made from cannabis flowers, which he calls “Sativa Cannanol.”

This development is interesting considering that, traditionally, black-and-white film development relies on commercially produced chemicals. Besides, photographers typically use alternative, homemade developers such as Caffenol, made with instant coffee.
