I didn't know his work and wow! I like how he embraces light leaks and uses chemistry in his work.
I'm not sure about this picture. The veil has no defined edges, maybe an alteration was done to the negative? Or was there an in-camera mask? It seems to be the result of light as opposed to chemistry. The black and white specks, on the other hand, are really defined, so maybe that was done directly on the print.
There must be an interview somewhere where he talks about his process. I'd be interested to find out!
