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.
Use an OCIO configuration file from your computer.
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 kritaflag 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.
- Allows you to study a single channel of your image with LUT.
- Set the general exposure. On 0.0 at default. There’s Y to change this on the fly on canvas.
- 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.
