Man Ray is the main influence on all my work.. For years I wondered how he did what he did. As I learned how to print for others I would always experiment with flashing light on paper.. to no real avail.
Problem was I had a Hydroquinone based developer and to make a good developer for Solarization/Sabbattier one needs a simple Metol based developer.
Another fine line of distinction one finds as you go down this wormhole is the maki line... you will notice in Man Ray's work there is a distinct BLACK line. When I started all my work I tried to keep away from
any visuals (portraits or nudes) to keep my work fresh but as well I did all print solarizations/sabattier which creates a white line, took me a few years to realize that I would never get the black line which I really love in his work. Therefore I bit the bullet and started shooting my images and flashing the negatives to the raw light using the same paper developer. Immediately I got the black line, so today I feel comfortable with both methods of creating the effect.
William A Jolly pdf was introduced to me on how to make this all work.. I highly recommend his discussion as he was completely correct in how to mix chemistry for this process.
Ed Buffaloe used this process as well , I think he was mostly working with print solarization and frankly his subject matter created fantastic maki lines but I always felt the work to be to busy and effect orientated.
Man Ray seemed with the negative solarization which creates a flat negative with black line, able to increase print contrast and print manipulation to make these fantastic shapes and forms that the OP has directed us too.
Man Ray, Brassai, Shelby Lee Adams, Brett Weston , Steichen these are my hero's who seemed to be able to tame a process and create with that process art prints that endure time.
