[Closed] Rendereffect color clamping

Hi!

I’m playing around with a scripted render effect, just to see how they work. Just for fun I tried doing a simple exposure control, to see if I could do something close to photographic exposure.

When I try and reduce the intensity of the image (at the moment just by multiplying the color values with a float), the highlights seem to be clamped. Is there a way of accessing the float or overexposed values of the image colors, and then editing them?

Thanks!
