LUT Management

../../_images/LUT_Management_Docker.png

The Look Up Table(LUT) Management docker controls the high dynamic range(HDR) painting functionality.

Use Open Color IO
Use Open Color IO instead of Krita’s internal color management. Open Color IO is a color management library. It is sometimes referred to as OCIO. This is required as Krita uses OCIO for it’s HDR functionality.
Color Engine
Choose the engine.
Configuration

Use an OCIO configuration file from your computer.

Note

Some system locals don’t allow you to read the configuration files. This is due to a bug in OCIO. If you are using linux you can fix this. If you start Krita form the terminal with the LC_ALL=C krita flag set, you should be able to read the configuration files.

Input Color Space
What the color space of the image is. Usually sRGB or Linear.
Display Device
The type of device you are using to view the colors. Typically sRGB for computer screens.
View
Components
Allows you to study a single channel of your image with LUT.
Exposure
Set the general exposure. On 0.0 at default. There’s Y to change this on the fly on canvas.
Gamma
Allows you to set the gamma. This is 1.0 by default. You can set this to change on the fly in canvas shortcuts.
Lock color
Locks the color to make sure it doesn’t shift when changing exposure. May not be desired.
Set white and black points
This allows you to set the maximum and minimum brightness of the image, which’ll adjust the exposure and gamma automatically to this.
