I put my light 15 inches above the screen and go for like 11 minutes. I also like ot put a black towel under the screen to prevent reflextion. It makes the edges crisper. Also if you go to a 305 screen its 9 minutes. Think of it as cooking the emulsion. if you have black max then you should be able to cook it real good.
Did you figure out the exposure times for your screens? From the looks of your video you were pretty spent that night. I saw the same look on my wife's face when I came home after work and she had been in the shop all day working on 30 shirts that were suppose to be delivered the week prior. I hope everything went alright for you afterwards.
The next time you order from Ryonet, add a 10 Step Gray Scale to simulate 10 exposures. Put it on every screen you expose for the rest of your life.
Aim for a Solid Step 7. Step 8 dissolves with water, step 7 survives.
The Stouffer 10 or 21 step scales both use .95 optical density for step 7.
The Stouffer T-2115 has been used as a standard photographic darkroom test positive since the 1930's. It's a real photographic positive with 10 or 21 steps of different density (steps), that simulates 21 different exposures - with one exposure. Because it's made under controlled conditions you can use math to calculate an exposure correction, and properly used, they will last a lifetime - and stop a lifetime of guessing.
