Stone DCTL is a slider-based curves tool for DaVinci Resolve, built by Nikita Petrovich. Instead of dragging points on a graph, you shape the image through sliders.
You can adjust the middle gray point while keeping the shape of the curves, with presets available for the middle gray point. RGB channels can be adjusted separately, and the Luminance curve has its own control. 'Blend' sliders let you adjust the power of each curve, and the curves use a smooth shape. A 'RGB Curve Visibility' slider changes the brightness of the RGB Curve overlay, which helps when curves become pure white due to the use of custom CST nodes such as OpenDRT.
Stone DCTL is compatible with DaVinci Resolve 16 through 21. Version 0.1.2 was released on July 21, 2025, and it is listed as free here. A demo video is available on the developer's page.
