Hi All,
Just wondering. Since it seems that a lot of TVs have over-emphasized reds (Red Push) to some degree and that it is more noticeable to us viewers especially with skin tones, why do we set up the color/tint with the blue filter rather then a red filter. I know that the proper color patches in the SMTE bars to set up the color/tint using a red filter are not in ideal positions although I believe I have read that the AVIA Calibration DVD has test patterns that put the corresponding red color patches together so one can use the red filter and set up the color/tint relative to the red levels. I have the Video Essentials DVD and all it says to help with red push is to turn down the color (saturation) until the red comes under control and this obviously turns down the levels of the green and blue. So you people that have the AVIA DVD and the red filter, what do the colors look like if you set the color/tint controls using the red color as your reference color. I assume that on a TV with some red push, that your greens and blues would actually be under adjusted but isn't that what happens when you just turn down the saturation control like the Video Essentials DVD says.
I don't have the AVIA disc but I can generate the proper color patches using Photoshop and then can burn them to a CD-RW as a SVCD/VCD which my DVD player can play. I don't have a red filter though. I understand that a suitable red filter can be bought at a camera store. What specifications for the red filter would I be looking for as I understand that there are numerous photography red filters available but obviously only one certain shade would be correct for purposes of calibrating a TV?
