[QUOTE="Horoscope Fish, post: 469500, member: 13090"] Well as I understand it, the software uses the twenty-four color chips (the little squares on the color card) in the reference photo you take to correct color in your images. All twenty-four of these chips have absolute color values that are known to the software. These same chips also have a color value in the photos you take. Color imbalances in your photos are corrected by comparing these two values against one another: If the RED Chip in your photo has a color value that does not match the known correct value, there is an imbalance and the software corrects it. The fact you have twenty-four color values to work with is just icing on the proverbial "cake". You also have different "White Balance" chips to work with to consistently warm up or cool down your images. Further, since the software has known correct color values to work with, it doesn't matter what the source of a color imbalance in the image is (camera body, lens or what have you). The software simply looks at the color value in the image and compares it to a known standard color value. [/QUOTE]
