I just heard about a new color space being adopted in the video world and wondered if anyone here knew about this and could explain a bit more about how it might fit in with the more standard color management practices we've used in the stills world for so long. Here's a clip from an email sent to me by Thomas Wall giving a brief explanation: "The ACES standard color space and the Image Interchange Framework that the Academy of Motion Picture Arts & Sciences has developed, and that is being adopted by SMPTE (among others), is almost unknown among photographers. This color space and interchange format will increasingly become the standard way of transferring files and archiving data in the motion picture and CGI industries. Photographers should also be using this format for the same reasons they do. The color space encompasses the entire visible spectrum, the entire CIE tri-stimulus gamut of human vision, and then some – wide enough to hold data from every foreseeable camera sensor and display technology without data loss due to out-of-gamut color coordinates. ACES is a linear color space; there is no baked-in gamma. It therefore matches the physical nature of light, the way that light sensors actually record it, and the way that computer graphics rendering is done. (Gamma adjustments are done as part of the output transforms for specific devices.) It is stored in floating point format, not as integers, and therefore has a dynamic range that goes from black to almost the intensity of the sun. It has a much more reasonable white point (D60, a standard daylight, and close to the REC709 white point used for HDTV) than ProPhoto RGB, and is larger than that color space. This color space, and the physics and logic behind it, are what we should be using these days; and products like LightRoom and CaptureOne should be able to produce and use it directly. We need to move beyond the dark ages of color management and image interchange standards. Whatever pressure we or the APA can apply to those software vendors, we should." Thanks!
