Definition of Academy Color Encoding System
The Academy Color Encoding System (ACES) is a color image encoding system created under the auspices of the Academy of Motion Picture Arts and Sciences. ACES is characterised by a color accurate workflow, with "seamless interchange of high quality motion picture images regardless of source".
The system defines its own primary colors as being on the spectral locus as defined by the CIE xyY specification. The white point is approximate to the chromaticity of CIE Daylight with a Correlated Color Temperature (CCT) of 6000K. Most ACES compliant image files are encoded in 16-bit half-floats, thus allowing ACES OpenEXR files to encode 30 stops of scene information. The ACESproxy format uses integers with a log encoding. ACES supports both high dynamic range (HDR) and wide color gamut (WCG).
The version 1.0 release occurred in December 2014. ACES received a Primetime Engineering Emmy Award in 2012. The system is standardized in part by the Society of Motion Picture and Television Engineers (SMPTE) standards body.
