Implementation of the Academy Image Interchange Framework

Several years ago, the Academy of Motion Picture Arts and Sciences formed a committee to study the use of a scene-referred image format for image encoding. The goal was to offer an alternative to the widely used printing density encoding. There were many factors motivating people to examine a scene-referred encoding including: making the compositing of real images with computer graphics easier to accomplish, a desire for increased dynamic range to facilitate higher-quality manipulation of images in post-production, and adopting an encoding that is better suited for material originated on digital cameras. In this presentation we will show that we have been able to successfully manipulate images in both the Academy system and the conventional Printing Density system. Conversion between the systems is relatively easy with the proper transforms. We will show that the same result can be achieved in either system. Thus people can work in whichever system is more convenient for the work that needs to be done.
