Hi Polyglot, yes, from now on, everything is going to be done in dark. I will keep cassettes for some kind of protection (still not sure from what?). My 70mm cassettes look "tired", with decent gap between felts, but where you can buy them new now? Most prices for 70mm film on Ebay are just crazy. You can almost buy any fresh 120 film in same quantity for less money. If this system of loading in the dark works, I'm not going to buy new ones.
You are right, 2405 doesn't look like it has antihalation layer. I can see it on very bright subject's. What Kodak emulsion are you using? Any idea how many of us here are using 70mm? Stone NY, you, me???
