In my last entry I mentioned that I would generate radiometric response functions for my Canon EOS Rebel SL1. Here they are as promised:
I generated responses for two white balance settings using the method from my previous entry:
The first is the ‘White fluorescent light’ white balance and the second is a custom white balance chosen using white paper and the camera’s built-in calibrator. I generated these responses because I wanted to see if they would differ based on white balance settings. From the results it is obvious that white balance does in fact alter radiometric responses.
The images shot at 4050K were warmer than those shot at 2850K . Is that what we see in the red response being more dominant over blue/green in 4050K than in 2850K?
 Going by the boxes my light bulbs came in my lighting is at roughly 3000K.
