Have you printed a digital step wedge?

Dan's 50 patch step tablet is a good one to use or Liam Lawless's 101 patch
tablet may even be better. Printed along side a standard Stouffers step
tablet can help lead you in the right direction perhaps. I would print these
uncurved to start with and evaluate the results. Sometimes using someone
else's curve doesn't really help.

A colorized negative will most likely help to reduce the need for an extreme
adjustment curve. You mat even want to try Keith Schreiber's faux pyro
