In the previous video I talk about finding the actual film speed. In that video I learn the darkroom exposure time by taking a blank frame (base plus fog) and finding the minimal time to get full black from this negative. That's the time/exposure I'm using as my standard. Very similar to printing the film rebate area full black but easier to explain.
Would be interesting to compare it with ISO 100 and 100% dev time.
It would be. Maybe I'll do that down the road.
One key thing that i dont understand, how are you determining enlarger exposure? Are exposing until film base goes full black.
