Levels override curves? Need help
Hey guys, I'm a longtime Lightroom user who just made the switch, and it's been pretty smooth so far.
One thing is still strange to me though.
After I set basic exposure, I use levels to set my black and white point. After that, I use the curves to lift blacks and crush whites a bit.
If I define the white point to Input=255 and output=230, my whites will still go over that value of 230 if I rip up the exposure or cut the whites in levels. Same thing goes for blacks, they will go under what I define them in the curves.
Is this intended? How can I fix this so the curves have the ultimate say over how bright a white/dark a dark is?
Thanks a lot
Nicola

AFAIK, the level b/w points (on the bottom of the "level" tool) defines the range of the input values (after exposure, contrast, HDR, etc.) that is then spread (mapped) to the full range (which is defined by the points on top of the levels histogram). So, if the levels map 230 (input=bottom) to 255 (output=top), the histogram in the curves tool will stretch, and the 230 value of the input becomes the new 255 in the curves. So, the read-out will show values that are higher than 230 (and the "Histogram" tool shows the full range as well).
I.e., the curves tool operates "after" the levels tool has mapped the range. And the bottom points represent then input while the top ones represent the output (which is a bit contrary to how the tools are arranged from top to bottom; you'd expect the input to be on the top and the output at the bottom).
HTH, otherwise I completely misunderstood your question 😊

That's right.I.e., the curves tool operates "after" the levels tool has mapped the range.

Except that if the input was at the top and output was at the bottom, how would you easily pull the sliders in to the edges of the histogram?0
