I’m too cheap to pay lots of money for color management solutions from X-rite. I already have a gretag-macbeth colorchecker chart, so that’s a sunk cost. I originally planned to use it to calibrate my scanner and camera. I wrote some MATLAB code to analyze the scanned image and did some tweaking on the settings to improve the color, but it was time consuming, because I had to do it iteratively. I looked at the documentation for the ICC profile and I think I can write some MATLAB code to adjust the colors. I think this project usurps the astrolabe, because I haven’t bought the astrolabe book required to design an astrolabe. I also want to scan some old pictures during the christmas break. I’ll put up the MATLAB code for it and try to make some money by putting an affiliate link to amazon for the color checker target.
