But each column carries out the exact same operation since the red, green and blue channels were all set to maximum. Why does only the calculation on the red go to zero for just 1 value in a nice simple count?
if it did it for all of them, i would understand, and i get what you guys are saying about dividing going below zero, but it works 99% of the time with that occasional hiccup. (as i saw from hyperterminal)
Thats what confuses me. But its ok.
