1. An automated RAW image processing method implementable by a processing device, the method comprising:

  • storing a plurality of predetermined tone curves, each of the predetermined tone curves derived by values of each pixel in a first reference image of a scene being paired to values of corresponding pixels in a second reference image of the scene, the first reference image obtained using a first camera, each of the predetermined tone curves generated based on the pairings and being associated with camera information for the first camera;

    interpolating a RAW image to produce an interpolated image;

    determining based on metadata associated with the RAW image which one or more of the predetermined tone curves to apply;

    applying the one or more predetermined tone curves to the interpolated image to produce a resulting image; and

    making the resulting image available to an application executing on the processing device.
