(a) LUT Browser button The LUT Browser appears, displaying the Lustre_Color_3DLUTs folder. 3 Open the folder and select a LUT from the Conversion folder. Drag it to the dependency graph in the Schematic. 4 In the 3D LUT tab, set the Exposure, Negative Film Gamma, Cineon Reference, and Linear Reference-see Modifying Negative Film Gamma, Cineon Reference, or Linear Reference Levels on page 628. The 3D LUT is applied. NOTE Exposure is an animatable attribute-see Setting Keys Manually on page 676 and Validating and Applying the Expression String on page 729. Working with ASC CDLs Composite supports the American Society of Cinematographers' Color Decision List (ASC CDL). The ASC CDL was developed by the American Society of Cinematographers in a unique collaboration between manufacturers, cinematographers, and colorists. The ASC CDL was developed to ensure that basic color grading adjustments can be shared amongst different manufacturer's systems, from on-set through post-production. The American Society of Cinematographers CDL color specification defines a common language for primary color correction. A CDL is expressed by nine numbers (three RGBtriplets) representing predefined color functions: offset, slope, and power. The ASC has defined a number of formats in which a CDL may be carried. Composite supports the form where a single set of CDL parameters is stored in an XML file. If you are working on a project in which the cinematographer is making use of CDLs, you can use the 3D LUT tool as a display modifier to preview your work in the context of the cinematographer's 624 | Chapter 26 Color Correction
