Well, above all, enjoy the adventure. Be patient with yourself and have fun during the learning curve. You might find yourself experimenting
with how specific film grain actually contributes or distracts from your intended look blown way up. Good luck!
Thanks guys - looked up how many cubic inches are in a gallon and started calculating chemistry for various tray sizes... gulp. Trying to keep it to 5 gallons... I'm going to have to think up a way to keep coated canvas very flat while wet... maybe I can get away with an inch or inch and a half chemistry depth...
Can you scroll the material? You will need less liquids if you use troughs - and getting the wet material in and out of trays would be less fraught if you have two people and a roll, rather than two people and a floppy sheet.
