Back to the original topic : I'm very glad this thread got revived; and we were given a succinct explanation of why color negs have traditionally
come out with so much pumpkin and poison green - and perhaps why they have improved so much in recent years. Right now I'm making prints
from color negs which almost anyone would think came from chromes, except that the white borders would be a giveaway. And yes, 30x40's
with registered masks would be unthinkable without glass antinewton carriers.
