Some years ago I photographed a young woman who went by the name of Isis. She was very beautiful. I printed one of the negs and placed the print in the developer. The phone rang and I turned on the light. I quickly remembered I had a print in the developer tray. I turned it off, but not before the lovely damage had happened. This is called a variation of the Sabattier Effect. The bright light on the developing paper somehow reverses the image partially. I don't think I could ever replicate this image if I tried.
A print that is reversed is called a solarized print. When it happens to a negative it's the Sabattier Effect.
