The Tone Curve Isn't a Mystery — You're Just Using It Wrong
I spent the first two years of my Lightroom life completely ignoring the tone curve. I’d drag the Basic panel sliders around until the photo looked okay, then close the develop module and tell myself I was done. The curve panel was just sitting there, that little graph with the diagonal line, looking complicated and vaguely threatening. I figured it was for professionals. Then I shot a set of live music photos in a venue with genuinely awful lighting, and no combination of Exposure, Highlights, and Shadows was saving them.
