Here’s a tonemapping plug-in, still a work on progress.
It’s a tonemapper based on the Adaptive Global Luminance mapping as written in the paper ‘Comprehensive Fast Tone Mapping for High Dynamic Range Image Visualization‘ by Jiang Duan, Guoping Qiu and Min Chen.
For now i have left out the more complex linear scale histogram equalization blend curve (the math goes far beyond my knowledge so i’m brushing up on my algebra abit before i’m able to implement that feature.)
Hello.
HoS_Tonemapper.plugin is very useful.
Thank you very much.
I want you to support Exponential and Reinhard tonemapping.

Sorry bad English.
Best regards.
Thanks for the kind words.
The Reinhard algorithm looks interesting, i think i read the paper before, looks like enough info is in the paper to implement it.
I really need to brush up on my algebra though.
That, and there’s only so much hours in one day, and right now i quite swamped with work.
Sorry for the delay.
I am looking forward to supporting Reinhard tonemapping.
Best regards.
I just downloaded. I can’t wait to test this out next week!

Also, Ashikhmin’s tonemapping operator is supposed to be inspired by human visual perception. The PDF is offline, but HTML converted content still online here:

Hey.
Did you find time to implement any other tone mapping methods in to this script? It would be really useful for my Vray renders!!!
