Accurate ACES Rendering in Systems Using Small 3DLUTs

The ACES color space has unlimited dynamic range, however, it is not so easy to implement ACES workflow keeping high quality on the grading systems currently in use. To this end, we proposed custom Log ACES and High Saturated Log ACES(HSLA) methods. The custom Log ACES can process negative ACES values and can handle high dynamic range. HSLA expands the ACES color space to reduce vacant area and spread real color data area in order to use 3D LUTs more effectively. These two methods drastically improve accuracy of color reproduction even if the post-production system supports less than 33 gird number of 3D LUTs.
