Re: Can anyone see what I'm doing wrong here? (CI Kernel)



This looks like an excellent test case for the ternary operator bug people have been seeing. I'll bet switching the ? : to "compare" would make the glitch go away.

It looks like some mixing of red and green are going on somewhere deep down. Could it be something like a bad conversion of the red component from 5551 16-bit color space (or 565) to 8888 32-bit color in some pipeline? Or some setting where when it's looking for the red value in BGR, it thinks it's in 16-bit mode when it should be in 32-bit mode? These would bleed green into red. Anyway, just speculation.

If you try moving the sliders, you'll see a couple of unexpected results.. the first and most obvious one is that the red curve is affected by the green value. The second is that if I set any of the inputs to 0.5, the peak of the corresponding curve is apparently lower than the midpoint of the output image.
