Stone DCTL

Curves is a commonly used tool, but when you want to adjust them just a bit, most times it goes much further than you wanted. Or when you want to take the curve from one color space and paste it in another color space, you cannot do it because the mid gray point is different. Stone DCTL will solve it all.

Features:

• adjust the middle gray point, keeping the shape of curves
• adjust RGB channels separately
• adjust the Luminance curve
• adjust the power of each curve with 'Blend' sliders
• presets for middle gray point
• smooth shape

Copy from one color space to another color space

You'll just need to change the pivot point or choose your color space from the Mid Gray presets. The shape of curves will remain the same. The result will be almost identical, as shown in the example below with DaVinci Wide Gamut, ACEScct, Arri LogC4 and RED's Log3G10. But keep in mind, output colors may vary a bit because of the color science of different color spaces.

DCTL applies RGB adjustments first, as if we adjust separate channels on the first node. And then it applies Y adjustments, as if we adjust the linked curve on the second node.

When we apply the DCTL, it uses the same curve twice. If you don’t want to apply the contrast twice and you don’t need to work with channels separately, you can use the checkbox 'Disable RGB'.

PLEASE NOTE: DCTLs work only in the Studio version of DaVinci Resolve
