Looking for Logarithmic Distortion plugins

[Water Boiled Pizza]

Hi, I would like to distort an image logarithmically as shown in attached. Any recommendation for methods/plugins to do so? Thank you.

I'm not sure if there's a distort that does it mathematically, but you can manually do the same with Grid Warp.

I don't have a suggestion, but I'm interested to know what your use case is for logarithmic distortion.

Could you post an example image that you wish to distort please?

Short answer: To revert a logarithmically distorted image.

 

Long answer: I am trying to show an image with Constant-Q Transform (CQT) as shown below:

and as you can see the image is stretched on the left. so i think i can revert it with a Logarithmic Distortion.

 

If you also want to try it yourself: Image to audio , ShowCQT bar
