Beyond RGB is a recently developed software application for colorimetric and spectral processing. Two sets of RAW RGB images (a dark current image, a flatfield, target, and artwork), taken under two different lighting conditions are used as the inputs. After processing, the software provides a color calibrated RGB image, along with the calibration accuracy, a spectral stack, and if applicable estimated spectral reflectance of regions of interest may be selected. The updates for this version of the software includes: dual screens for simultaneous file comparisons, updated a*b* and L*C* plots showing the actual and expected values, batch processing, meta data allowing for precision reproducibility for color calibration, and user interface upgrades.
