Many years ago a Photographer that had worked his entire career from Teenaged Apprentice to eventual Septuagenarian Owner at a venerable old New York Portrait Studio, taught me to spot B&W prints using Japanese Sumi ink. I loved it and have never used anything else since then. Tonight, as I am finishing up a few prints, it occurred to me that I have no idea whether anyone else is spotting with this stuff. I am just curious, have any of you spotted with Sumi Ink? How'd you like it?
