Hi,
Learnig some video editing applications, I found a tool called "parade", which splits the image into the RGB channels. I thought it that might be useful to show what the white balance controls do, specifically the "Temperature" and "Tint" sliders.
I have created two animated gif files attached to this message.
The first animation shows the effect of the "Temperature" slider. This could be called also red/blue gain, note how the green channel is unnafected.
The next one shows the effect of the "Tint" slider. Again, this could be called green gain.
I wonder if the choice of names "Temperature" and "Tint" are really the best for the application.
