Flujo de trabajo lineal

Different Color Spaces are needed for rendering, display and storage of images.

Rendering and compositing is best done in a scene linear color space, which corresponds more closely to nature, and makes computations more physically accurate. Blender primarily works with scene linear colors for materials, lighting, geometry and compositing.

However, these values do not directly correspond to human perception or the way display devices work. Image files are also often stored in different color spaces for more efficient compression.

For a correct linear workflow, it is important to assign the correct color spaces for images and displays. Blender will then perform conversion to and from scene linear colors.

Color space used for all scene linear colors in this file, and for shader, compositing and geometry nodes processing. The default is Linear Rec.709, while Linear Rec.2020 and ACEScg are available for working with a wider gamut of colors and compatibility with ACES workflows.

The working space affects the colors of all data-blocks in a file, and has a significant effect on rendering and compositing results. Generally the working space should be chosen at the start of a project and used for all blend files.

Blender can convert between different working spaces, however this is only an approximation and manual fix-ups are typically needed. When linking and appending data-blocks, colors are automatically converted to match the current file.

Editor de video

El espacio de color en el que operará el Editor de video. De forma predefinida, el Editor de video operará en el espacio sRGB, pero también será capaz de funcionar en un espacio Lineal (tal como lo hacen los nodos de composición), o en otros espacios distintos. Los diferentes espacios de color proporcionarán resultados también diferentes durante la corrección de color, fundidos cruzados y otras operaciones.

Los espacios de color soportados de forma predefinida se describen en detalle aquí: Espacios de color incorporados.

Imágenes y video

When working with image and video files, Blender will automatically try to guess the right color space. If this is not correct, the color space of the image file can be configured in the image settings.

A common situation where manual changes are needed is when working with or baking normal maps and displacement maps. Such maps do not actually store colors, just data encoded as colors. Those images should be marked as Non-Color Data.

For intermediate image files in production, it is recommended to use OpenEXR files. These are always stored in scene linear color spaces, with high precision to avoid data loss. That makes them suitable to store renders that can later be composited, color graded and converted to different output formats.
