Tone Curve

"Tone Curve" feature offers the same possibilities as the Curves tool, however its settings are stored in sidecar XMP files. So, it may be useful, i.e., for "non-destructive" corrections of 16-Bit photos.

1. For a quick tonal correction, choose a suitable preset in "Curve" menu (fig. 1).

2. To modify the curve manually, click "Edit" button (fig. 2) and make the required changes in the "Curves" dialog that opens (fig. 2/1).

3. In case later on, you decide to reshape the curve, open "RAW Corrections" dialog, go to "Tone Curve" tab, and click "Edit" button (fig. 2).
