Thanks for letting me know about that. If it’s such a simple mapping, then I could look into it. I figured the DR would be more of a dynamic range compression, and it was darkening some areas and brightening others, so an exposure change would not replicate it very well. For your test images, if you move either Exposure of Whites, are you able to get the results you want? Also, what amount do you move each slider for these various DR values?
