Color Grading plug-in, creates a cine image look based on user input. For a
contemporary image look, use complimentary colors in shadows and
highlights. It is also preferable to be used on a somewhat neutral image
(ie pre white balanced) for best control of the final result. If it's
not a raw image balance it before with Color Balance 2 (http://registry.gimp.org/node/24589).

FILES TO COPY:
For normal installation copy:
color_grading_cw_v171.py
colorwheel_150.png

If above is not working, copy:
color_grading_cw_v171_safemode.py
colorwheel_150.png

If you are a developer or studying the code you can use:
(The developer version generates the colorwheel if .png file is not found, requires numpy installed, numpy is not automatically installed in Windows)
color_grading_cw_v171_developer.py
If color_grading_cw_v171_developer.py is not working then try:
color_grading_cw_v171_developer_safemode.py

Btw, your other plugin Color_balance 2 works fine :)

Wish List
Is the next version is possible to add recording settings (Profiles: load / update / save as / delete - for example Border Line http://registry.gimp.org/node/24784 ) ?

Nice feature, it will be added in the next version(s).

The option to save the settings that is great.
Amazing opportunity to play with colors (from 2.6 to 2.8 RC1).
Thank you very much !

Thanks for the feedback. I had all of the libraries installed. The file was not marked as "executable". All is happy now. Looking forward to exercising your plug-in.

Regards,

IndyTim (aka DataMan)

Doesn't build in the filters menu. Mint Gnome 10, GIMP 2.6.10.

Have you tired to run any other python plugins in GIMP? If not, there are probably missing libraries. Do you have installed Python 2.x? Do you have installed PyGTK, PyCairo and PyGObject? The .py file is marked as executable (see file properties)?
