Introduction

The RAW to ACES Utility or rawtoaces, is a software package that converts digital camera RAW files to ACES container files containing image data encoded according to the Academy Color Encoding Specification (ACES) as specified in SMPTE 2065-1. This is accomplished through one of two methods.

1. CameraRAW RGB data (generated by libraw) is converted to ACES by calculating an Input Device Transform (IDT) based on the camera's sensitivity and a light source.

2. CameraRAW RGB data (generated by libraw) is converted to ACES by calculating an RGB to XYZ matrix using information included in libraw and metadata found in the RAW file.

The output image complies with the ACES Container specification (SMPTE S2065-4).
