OpenColorIO (also known as OCIO) began development in 2003 at Sony Pictures Imageworks and it became an open-source project in 2010.
#AUTODESK FLAME COLOR MANAGEMENT SOFTWARE#
Color management software is responsible for accurately translating between these many different digital representations of a given color appearance. Furthermore, the visual effects industry has its own set of color spaces, different from those of either capture or distribution, and pioneered the use of scene-linear floating-point color spaces. The entertainment industry has many ways of encoding color digitally into what is known as a "color space." For example, the different digital cinema camera makers each have their own distinct color spaces, and likewise, there are numerous different color spaces that are used for distributing cinema and video (in both standard and high dynamic range formats). Color management is the technology used to ensure that color appearance is communicated correctly as images journey from cameras on set, through post-production and visual effects, out to the many distribution channels (cinema, tv, streaming, etc.), and finally into a studio's archive.Ĭolor is a complicated phenomenon that involves not only human perception and aesthetics but also math and physics. OpenColorIO is an open-source software component, widely used in visual effects and animation, that provides color management technology. For these situations, it's best to use a fully invertible transform to preserve as much color information as possible.I'm Doug Walker, Senior Principal Software Developer at Autodesk, and my team and I have been hard at work on a software infrastructure that the industry relies on - OpenColorIO - OCIO for short. As you work, you may want to switch color spaces to perform certain operations, and then switch back to your main working space or a different space for other operations. Some operations work best with colors in a specific type of space: scene-linear, video, or log-encoded. They have wide gamuts, but they are not too wide. It can be used as a working space, but some color operations may give unexpected results because the gamut is so wide.ĪCEScg, ACEScc/ACEScct, DCI-P3, ProPhoto-RIMM, or UHDTV (Rec. 709/sRGB primaries are still the most commonly used for scene-linear working spaces.ĪCES 2065-1 is an extremely wide-gamut color space that can represent any visible color. Autodesk Color Management is able to preserve negative values, but other tools may not.
709 primaries (used by sRGB and HD video) without using negative values. For example, digital cinema (DCI) contains colors that cannot be represented using the Rec. This ensures that you can properly represent as many colors as possible. In general, it's best to use a wide-gamut color space for working. In addition, some applications let you switch between color spaces for specific operations. Images are automatically converted from their input color spaces to the working space on import. Autodesk Color Management lets you use any color space as your working space, and supports many of the common and standard color spaces.
