What parameter do you modify here? The > "shadows" slider? yes, indeed. My steps were as listed above: 1. set exposure to remove clipping 2. set the black point (both done on the histogram) 3. then moved to "Shadows and Highlights" which open sliders starting with "Shadows" and "highlights" come second (followed by others) 4. when I get there "shadows" slider stands at 50 and "highlights" at -50 5. when I now move the "shadows up to 52 and higher (like60) the dark parts do get lighter. so far so good. 6. when I move the slider back to 50 it does get a little darker again but ist MUUCH lighter than it was at 4. That should not happen, should it? (but then: its not a big deal, remove the Shadows&Highlight and compress the history stack.
