For what reason is this tool recommended before using NLP? What will be the differences of the new created tif to that before?

Used the tool before white balancing. The TIFF are significant lighter (the negatives). How work on? Take these gamma-TIFFS an white balance these and convert them? Can the new TIFFS stacked with the Original or is a Subfolder the way to go?
