lightened the image using levels, ran NI, and then darkened the image with 0.8.
What benefit is there in lightening the image before running NI?
Why this workflow?
I think this is a question for Mitch Weintraub because any post-processing before NI is not something we generally recommend. It doesn't hurt when you process a single image, but in general it is better to not apply any postprocessing before NI to make re-usable profiles properly match your workflow (they should be built and used using the same workflow and in the same part of the workflow).

Thanks for the clarification. The same workflow-related comments apply to s/h. If you want to simplify re-use of pre-built profiles, do not apply any post-processing before NI. If you don't use pre-built profiles (if you build a new one for each input image) then it doesn't matter whether you apply some postprocessing before NI or not (well, sharpening is anyway not recommended before NI).
