From Canon Europe:
Canon has announced that Canon Log look up tables (LUTs) for its EOS C300 and EOS C300 PL Digital Cinema Cameras are now available for download to allow for converting Canon Log Gamma footage.
The EOS C300 (EF lens mount) and EOS C300 PL (PL lens mount) cameras are part of Canon’s Cinema EOS System and amongst their specifications they offer Canon Log Gamma, which enables neutral image quality with subdued contrast and sharpness for a wider dynamic range (up to 800% or 12 stops of latitude). This allows for more image information to be retained for colour correction and visual effects, hence greater freedom in post-production and colour grading.
The EOS C300 and EOS C300 PL Canon Log LUTs are available in three different versions: one for converting from Canon Log Gamma to Video gamma, one for converting from Canon Log Gamma to Cineon gamma, and one for converting from Canon Log Gamma to Rec.709 gamma.
