Setting the Custom WB panels for my new Hap Griffin Modified 350D. I have the Baader IR block filter mod. Notice the big difference in the images with the stock filter removed and the Baader filter installed.
Also notice how much more red is transmitted with the CLS filter attached to the scope, as demonstrated by the Custom WB Calibration panel for the CLS filter.
Go to the White Balance Studies with Unmodified 30D
and see how the Calibration panels are completely different between the two cameras with the different filters. Amazing.
