ABSTRACT:
A method for determining visual calorimetric values for an object having particular spectral reflectance characteristics comprises the steps of: (a) photographing an object with an electronic image capture device to form device image values; (b) selecting a transform from a plurality of transforms for converting device image values to visual colorimetric values, wherein the selection of the transform is based on the particular spectral reflectance characteristics of the object; and (c) applying the selected transform to the device image values to determine the visual colorimetric values for the object.
