Accuracy of Color Calibration. Probability distribution of dE*ab errors between the patches of the images and spectrophotometric measurements. Based on 39 images (Nikon D200) & 15 images (Canon 10D) under different illuminants and settings. Median dE*ab is 6.40 for the proper patches of calibrated normal images, 17.75 for uncalibrated images.
