If you're wanting to use the step wedge to plot your traditional H&D
curve that everyone is used to looking at, there exists a formula for
converting %black to log density (reflective). It's called the
Yule-Neilson curve and it can be easily plugged into an excel
spreadsheet to convert %black to reflective density. Here's a link to a
site that has a .pdf file with this discussed:

Thankfully, it is in English instead of Finnish.
