Thank you, I understand the information loss if too high or low, clipping…
Actually now that I look, it was set to waveform, not the histogram…
So now it actually looks like I still had more room to go down to the “zero” I was thinking of… but now it says the waveform is clipping highlights, but the histogram is not past 255 in clipping…Should I be as close to zero unless I want shadow detail…I’m sure that’s all it is for that “contrast” preference…
