HUE TWIST & BEND DCTL


INTRODUCTION

The “Hue Twist” DCTL twists hue values towards their neighboring colors based on the brightness of each hue. Darker areas shift towards the opposite adjacent hue compared to lighter areas, adding complexity to the color manipulation process beyond standard hue shift methods.

The tool offers flexibility in setting the brightness threshold and controlling the intensity of transitions between bright and dark regions. This added control allows for broad and tailored image manipulation.

Overall, the “Hue Twist” DCTL is a precise color grading tool that uses brightness as a determining factor for hue adjustments, expanding creative possibilities in color grading.

TWIST

The “Hue Twist” DCTL adjusts hues based on their brightness. Bright areas are shifted towards one neighboring hue, while dark areas are shifted towards the opposite neighboring hue.

BEND

The “Hue Bend” DCTL adjusts hues towards neighboring colors based on their brightness without shifting them to the opposite hue. The Luma Low/High Slider lets users choose whether highlights, midtones, or shadows are “bend” towards neighboring hues.

EXAMPLES

In the first example, I am shifting the shadow area of the blue value more towards magenta, which will simultaneously shift the blue highlights more towards cyan. In the second example, I do the exact opposite. I am shifting the shadow area towards cyan, which will simultaneously shift the blue highlights more towards magenta.

FILM PRINT MATCHING

With the “Hue Twist” DCTL, you can replicate certain characteristics of Print Film LUTs, such as the popular Kodak 2383. This tool enables precise color adjustments, capturing the subtle nuances associated with different film stocks.

Notice the tool’s ability to reconstruct the specific green and blue of the Kodak 2383 print LUT. Using the “Hue Twist” DCTL, we can shift the lighter green values more towards cyan while ensuring the darker shades remain within the green spectrum. This process mirrors the unique properties of the LUT.

FEATURES

Enhance or minimize the overall hue twist effect by simply adjusting the “Luma Range” Slider. Decrease the value to create a steeper, ‘harder’ S-Curve. Increase the Slider to make the curve more linear and subtle. For a visual representation, click “Show Splines”.

“Hue Twist” is versatile, operating seamlessly on PC, Mac, and Linux platforms. It has been rigorously tested with NVIDIA and AMD GPUs on PCs, as well as with the M1 chip on Macs, leveraging both CUDA and OpenCL infrastructures. It’s crucial to note that DCTLs are only supported in the DaVinci Resolve Studio.

Minimum Requirement:
CPU: Intel Core i7, AMD Ryzen 7, or Apple M1
RAM: 16 GB
GPU: 4 GB VRAM

Recommended Requirement:
CPU: Intel Core i9, AMD Ryzen 9, or higher-tier Apple Silicon
RAM: 32 GB
GPU: 8 GB+ VRAM

KNOWN BUGS

1. The odd appearance of the “Cyan” icon on macOS is a harmless display bug that can be safely ignored.

2. When using DCTL with mini panels, DCTLS with emojis in it may lead to
disconnections. To avoid such issues NE DCTL versions are included.
(NE = no emojis)
