I did a series of split-grade density test strips. I tried grade 00 at 20 seconds, plus grade 5 at 5, 7.1, 10, 14.1, 20, 28.3 and 40 ses (half-stop sequence). The results are interesting. You get a range of "paper grades" from about 0 to about 3, but with much different toes (highlight separation is increased) and shoulders (shadow separation is reduced), compared to the base curves.
Following up on the curves I posted earlier, I had Claude write Python to turn the S curves into Photoshop-style curves, and animate them from softest to hardest. The results were not what I expected -- not at all a "smooth" evolution from first to last. The "deviation animation" shows how the brightness at each input point differs from an ideal linear 1:1 conversion

I tested my paper and printing workflow and got some interesting curves. See alt-text for tech details.
Most interesting: grade 2 and 2.5 are virtually identical (except that grade 2 is denser). Grade 1.5 and 2 have virtually the same calculated ER. Is this due to the high-CRI LED I'm using instead of an incandescent? The no-filter curve would do interesting, possibly attractive, things to gamma. Next weekend, if I have time: check split-grade (00+5).

I followed this procedure, based on aas.org's notes and darksky's notes. I'm going to need to thread it, so bear with me.
- Log in to CORES: https://apps.fcc.gov/cores/userLogin.do -- leave this open, request security code, and enter it once it arrives. (It takes two minutes or so for me.)
You'll get to the 4th screen. Leave it open. And go to the next step.
