From what I have learned, the red one has a true iso of 320.
I was wondering if something like this could also be true of the color temperature. I have heard a lot of people mention that it doesn't perform as well under tungsten lighting compared to daylight. I want to know if that is because it is truly balanced for daylight.
If that is the case, then would using an 80a filter, or whatever is appropriate on the lens, result in better results then just changing the color temp in the camera?
