How it differs from exposure
Exposure moves the whole image. Tone Curve can move shadows, midtones, and highlights separately.
You can tighten shadows, soften whites, or keep skin in place while changing the overall weight of the image.
SELON Manual / Tone Curve
What is a Tone Curve?
Tone Curve reshapes brightness relationships across the image. In SELON, it is used to control weight, softness, and openness.
Chroma Curve
SELON also treats Chroma Curve as important. It adjusts how color remains without simply changing brightness.
The point is not to make colors loud, but to control how much color sits on the photographic surface.
