While setting up a shot today under 3200k light, I noticed that as I moved my preset from 5500k to 3200k my light meter moved.
In thinking about this, I am curious as to what is happening.
1. Is the camera more sensitive to light in the 3200k range (doubtful)
2. Is the camera bringing up the gain in the red sensor when 3200k is selected?
3. Something else?
I've read any number of sources that say that the blue channel is the noisiest and thus giving cameras more light to work with in the blue channel (daylight balanced versus tungsten) will give a cleaner image. Given that, I thought this was odd behavior from the EX1.
Anyone want to comment?
