Just used good old metal tanks and reels. I did a print last night of a VERY white building. I was amazed at the tonal range. Everything from white to black and lots of shadow detail. Definitely has it's own look, but certainly has applications. Worth continued efforts for sure. And sharp! Boy I didn't realize just how sharp that old 50mm Blad lens was.
When I get my new scanner set up I will post a scan. Not sure the shadow detail will show up, but I'll give it a try.
