Look-Up Tables (LUTs) are a common implementation for transformations from one set of color values to another. With a large number of product developers providing software and hardware solutions for LUTs, there is an explosion of unique vendor-specific LUT file formats, which are often only trivially different from each other. This can create workflow problems when a LUT being used on a production is not supported by one or more of the applications being used. Furthermore, many LUT formats are designed for a particular use case only and lack the quality, flexibility, and metadata needed to meet modern requirements. The Common LUT Format (CLF) can communicate an arbitrary chain of color operators (also called processing nodes) which are sequentially processed to achieve an end result. The set of available operator types includes matrices, 1D LUTs, 3D LUTs, ASC-CDL, log and exponential shaper functions, and more. Even when 1D or 3D LUTs are not present, CLF can be used to encapsulate any supported color transforms as a text file conforming to the XML schema.

Abstract
Look-Up Tables (LUTs) are a common implementation for transformations from one set of color values to another. With a large number of product developers providing software and hardware solutions for LUTs, there is an explosion of unique vendor-specific LUT file formats, which are often only trivially different from each other. This can create workflow problems when a LUT being used on a production is not supported by one or more of the applications being used. Furthermore, many LUT formats are designed for a particular use case only and lack the quality, flexibility, and metadata needed to meet modern requirements. The Common LUT Format (CLF) can communicate an arbitrary chain of color operators (also called processing nodes) which are sequentially processed to achieve an end result. The set of available operator types includes matrices, 1D LUTs, 3D LUTs, ASC-CDL, log and exponential shaper functions, and more. Even when 1D or 3D LUTs are not present, CLF can be used to encapsulate any supported color transforms as a text file conforming to the XML schema.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
