The exposure test confirmed that, as I remembered, the vac frame glass needs 50% more exposure than the plain frame, which also sits a little closer to the tubes in the pizza oven configuration. To use the other half of the sheet I'd coated, I decided to output a new step tablet with a more gentle curve applied to it. I think my earlier tests are actually a little too contrasty in the middle values, so I'm pulling back on that.
Looks promising in the developer.
Really nice and smooth in the wash tray. Need to examine it dry to see for sure what's happening.
