Hey there,

does anyone know a way to clip the blacks or the whites of an image? I would like to achieve the "opposite" of the clamp node. Just like the Levels in Photoshop. Maybe there is a way to build this effect with other nodes.

Thanks in Advance!

Hi Hesekiel2517,
do you mind to share a screenshot of the desired effect?
If I have understood it correctly, the Gradient or Color correction node could be used, I guess.

Thanks for your answer. I want to have this control and i also would like to animate it. So it would be great if there was a combination of nodes where i can change a single value to get this effect.

Hi Hesekiel2517,
vary basic example, but if you move the black or white point of a Gradient node, you should have a similar effect:
