RAW Format

RAW is not like the RGB or CMYK color spaces. The image information isn’t broken down into components like you might expect. Instead, RAW stores data that can be turned into an image. The data itself is meaningless until another process can convert it into an image.

Under the Hood Options

Many of the options that exist in the LUT Management docker will not appear to do anything. These options are more for how color profiles and settings are calculated between the image and the monitor. Here is an overview of the different settings and Color Engines that are available:

• Internal(default) – This will use Krita’s built-in color management system to determine color modeling and information. The Internal color engine ensures that all of the colors are displayed correctly on screen. Most of the options are disabled on the docker when this is selected.
• OCIO – Gives the OpenColorIO engine full control of the color management system for your document. You can load in configuration files that outside applications support.
• OCIO (environment) – Similar to the regular OCIO setting, but the configuration points to your machine’s OCIO environment variable for the configuration.

Shortcut

Change the exposure level by holding down Y and dragging your pen up or down. Changing the exposure will adjust the light that defines your colors. This will either make your colors lighter or darker.

Configuration Options

If you visit opencolorio.org, you can download some predefined configurations that specific applications use such as Nuke or Sony Picture Works. In the LUT Management docker, the configuration files specify the following properties:

• Input ColorSpace – Specifies the source image’s color space.
• Display Device – What type of device will the final image be outputted to? A common display for monitors is sRGB.
• View – Simulates the way your image looks on a screen.
• Components – How the color information will be separated. This closely corresponds to the channels for the image.
• Lock current color (icon) – Lock the foreground color to have the same appearance when changing between configuration files.
• Configure black and white(icon) – A normalized value range where you can specify where black-and-white values occur.
