GLOBAL TONEMAPPING OPERATORS 1.5
colour-science.org - July 10, 2016
The attached file is a playground for implementation of various Global Tonemapping Operators. They are available as groups and can be copy / pasted quickly from the file to another.
The following operators are currently implemented:
- Schlick (1994)
- Reinhard (2004)
Examples with the following source image: http://rit-mcsl.org/fairchild/HDRPS/Scenes/HDRMark.html
Because Nuke is unable to perform realtime computation of image average, min and max values, some operators need a domain precomputation.
More information is available in the following IPython Notebook: https://github.com/colour-science/colour-hdri/blob/master/colour_hdri/examples/example_global_tonemapping_operators.ipynb
Latest version of the file will always be available at this url: https://github.com/colour-science/colour-nuke/blob/master/colour_nuke/scripts/global_tonemapping_operators.nk
There is a bug in the Reinhard implamentation.
I guess it is some left over code.
In the I_a_tonemapping _operator_Expre ssion there is a unused expression variable that throws a error. It should be removed.
I'm having problems with displaying properly image after conversions. Can we contact somehow ex. e-mail?
