The Apple Store AccuRaw description looks interesting especially in regards to "color accuracy" and avoidance of "Hollywood Colors".
The User's Manual on that page's Support link (takes you to a Google page) has some intriguing info on Processing Options for Scene Referred/Highlight Recovery...
Scene Referred. Raw images are usually processed with a tone curve that mimics human vision (for example, see "General-Purpose Gamut-Mapping Algorithms: Evaluation of contrast-Preserving Rescaling Functions for Color Gamut Mapping", Gustav J. Braun and Mark D. Fairchild). However this default can be overridden by deselecting "Scene Referred".
Are there before and after sample renderings to get an indication how "accurate" this Raw converter renders color and tone?
