ARRI Color Tool is a free utility for creating the new ARRI Look File 2 for ALEXA LF, ALEXA SXT, ALEXA 65, ALEXA Mini, and AMIRA cameras. You can use the ARRI Color Tool to create a completely new look or modify an existing look based on Log C Apple ProRes clips or Log C *.dpx grabs from all ARRI cameras.
Some third-party post processing tools do not support ALF2 looks natively. ACT allows one to export 3D LUTs in order to be compatible with these tools. ACT is available for Mac OS X and Windows x64.
