Why did you not set the camera to auto exposure and why did you defocus? .

I DID add blue filter to the one on the right. The filter I added would
correct 4850K to 5250K. I probably should have used 6000K. I will redo.
Why not auto exposure? Because then the comparison would not be real.
This is VERY important ... if you use autoexposure it will automatically change
the color temperature setting.
Why defocus? This is very important! Its perfectly possible to
focus accurately. This means, using my camera, that the camera
resolves the individual color dots or rectangles. To get accurate color
rendition you then have to set the camera exposure so that the brightest
dots do not overload the sensor. This results in a VERY dark image!
So if you don't defocus the camera you have do the defocus
in Photoshop if you want the whole screen in one image 900 pixels
high or less so it can be posted on Videokarma. I have posted pics
of my CT-100 showing the dots clearly.
The Sony is two years old and is calibrated as best I can to about 6000K,
just using a test DVD. The Sony is identically calibrated at least
by intent.
Getting good pictures of color TVs is not easy! It is very much not a matter
of using auto settings on a camera!
