Calibrating the camera

I wrote about the colour deficiency of DSLR sensors in the
Pond Musings: The Digital Divide

Today I tried out Tom For's calibration script. I actually went so far as to shoot a Gretagmacbeth chart for 5 lenses on three different light banks. I have only got one lens and light bank calibrated so far as the calibration process takes about half an hour. All I can say is that the results are promising. Not only is the image neutral, the red, green and blue patches on the chart look really good. My assistant's skin tones were more natural after calibration as well.

I am excited about this. After calibrating the lenses with studio lights, I intend to calibrate the lenses with my Cosmopro fluorescent lights and outdoor daylight.
