Hmm, I’m not sure what I’m doing differently from you @sls141. I’ve played with the Clamp Input slider, but achieved nothing like what you got. The variation in brightness is still very apparent in my image, but your image has a very uniform brightness. I tried setting the Clamp Input to 1.42, as in your screenshot, but that doesn’t improve things (as per my screenshot below).
Your Input Levels graph is quite uniform, similar to a bell curve, but my graph is a lot more varied and spread out. That seems to be the only difference between our Adjust Color Levels settings. Any idea why the graphs are different?
Thanks again!
