Hi Alan, I've been doing serious photography since 1953 when I was flying F-84s in Korea. And yes, I remember bulk loaders. I used to buy 100' rolls of Tri-X and Ilford HP-4 and roll my own. Always made me feel free.
I love my D800, but I still love my D3. If I'm shooting something like a play rehearsal I'll shoot with the D3. Makes PP a lot easier. But nothing I've seen can beat the D800 for landscape and wabi sabi.
