This Technical Report provides information about methods for determining scene analysis transforms based on the minimization of errors in estimated scene or focal-plane colourimetry, including corresponding colourimetry. These transforms are limited in applicability to raw DSC image data.

This Technical Report concerns only the creation and encoding of scene-referred and focal-plane-referred image data. It does not address the encoding of output-referred image data. It also does not provide information relating to the specification of metadata items describing intended artistic adjustments, colour rendering and viewing.

This Technical Report does not address how to choose adopted white points or how to process scene-referred image data to produce output-referred image data.

This Technical Report is not intended to be comprehensive or complete; it is an overview intended to enable improved practices and communications.
