You can get a version of blender at Graphicall.org (any version above revision 27733)
There is still some precision issue on the color wheels, I guess some day it will be possible to move the color picker slower.
How to use it ?
First I would recommend you to un-check the “color management” setting in Blender 2.5 or it will make the blacks really hard to control.
If you are not so familiar with color grading, and push-pull techniques, I would really recommend you to watch Stu Maschwitz’s (Prolost) video tutorial using Magic Bullet Colorista. The settings won’t be exactly the same, but the approach quite the same though !
How does it works ?
I described the Lift/Gamma/Gain in a previous post, and mostly this node is based on the formulas specified there. We just slightly modified it so the 3 defaults values parameters are equal to 1.0 just like in Colorista. Which makes it much easier to control the blacks.
Actually the “Color Balance” node before this revision was the same formula but with lift default value equal to 0.0
Some presets !
While making some comparison test between Colorista in After Fx and the “color balance” node in blender, I tried to mimic some of Colorista’s presets.
You can download the “Blender Color Grading Presets” here : http://code.google.com/p/ft-projects/downloads/list
There is the following presets :
- Cool – warm
- Day to night
- Vignetting (based on this tutorial I did on mask, but much better and flexible, just check it out) UPDATE : add Mike Pan’s vignette, which is much better than mine. Describe here : http://blog.mikepan.com/the-making-of/
