Hi,
I have question about the Tone Mapping Persona tools which I really love. I would like to better understand what is happening under the hood when using Tone compression tool and Local Contrast.
Usually for realizing what some tool does I use SliceTool in Nuke, which shows me what is happening with the curve after using the tool. On images below we see what tonemap tools do to the curve of the linear gradient ramp. Some results are pretty crazy like when local contrast is combined with Tone Processing.
I thought that if I apply same curve as I got from Tone Processing with a normal Curve Adjustment I will get same result, which is not truth. Here is an example.
I would like to know what is happening to the image under the hood with Tone Processing and Local Contrast. I am curious if this effect is possible to replicate with other adjustments or tools. For example lately I use 3DLut Creator with Affinity, I am interested if this effects are possible to recreate with tools in 3DLut Creator and save it to .cube file. If anybody knows more about this topic please enlighten me.
