For those of us who don't use Photoshop, can you provide a link to a description of HDR Toning?

If I knew what "HDR Toning" was, perhaps I could suggest how to implement it in ImageMagick.

Hi,

HDR Toning is present in photoshop under "Image/Adjustments/HDR Toning" and it has many options which effects on image.
Please see the image which shows the original image and converted image as per the below options.
- Method should be Local Adaptation
- Preset should be Default

Right side image is the original image and left side image is the converted image.

Please let me know if any further details required.

No one knows exactly what Photoshop does, except the Photoshop team. It is proprietary code. So unless there is a reference paper that was used by Photoshop to code that, we cannot reproduce it.

However, I have several tonemap bash unix scripts that you can try at my web site listed below, if you use a Unix-like system, including Windows 10 or Windows w/Cygwin.
