Abstract
An automated RAW image processing method and system are disclosed. A RAW image and metadata related to the RAW image are obtained from a digital camera or other source. The RAW image and the related metadata are automatically processed using an Operating System service of a processing device to produce a resulting image in an absolute color space. When automatically processing, a predetermined tone reproduction curve is applied to the interpolate RAW image to produce the resulting image. The predetermined tone reproduction curve is derived from a plurality of reference images and is selected based on the metadata associated with the RAW image. The resulting image is then made available to an application program executing on the processing device through an application program interface with the Operating System service.
