Color Correction in Blender Demystified
Ethan Luo explains color correction in Blender.
Weelian Soh writes:Ethan Luo or CongCong009 has produced an excellent video presentation explaining color correction and how to accomplish it in Blender. I personally have learned a lot from watching it. Highly recommended for anyone wanting to know more about Color Correction in Blender.
You will have to excuse Ethan as he is not a native English speaker, but I personally have no problems understanding what he is trying to explain.
Awesome contribution. Very useful information, thank you so much. :)
Great video. I learned so much!
Well.. I must say that color correction tools are slow and clumsy at this point.. For example color weels. I think some sliders would be good too for darks, mids and hights. But the main thing.. very slow.
That is correct and totally agree! The color weels is not the best tool to correct the color IMO. It failed on accuration mostly. The picker tool may work nice but I prefer too with you to get some sliders. Meanwhile the VSE need more improvement for the tool’s panel. I believe Mango team must have done many jobs already, we may just wait for their merge and release. :)
What I’d like to see is the ability to set up nodes for color correction and effects on each clip in the VSE. Blender’s compositing tools are quite robust, and it’d be amazing to be able to leverage that on a clip by clip basis.
Oh hey, I just thought of a way that you can do that. It’s very cumbersome, but it does work. If you set up each clip as it’s own scene and use the compositor to set up the video input, node chain, and output then insert each scene into the VSE you can use the compositor on each clip individually. The VSE Preview doesn’t like it much, but it renders correctly.
I have noticed that between 5:28 and 8:15 the Author has confused the bits of the color depths.
He thinks that “8-bit” color in his Photoshop means “8-bit per pixel” (and describes it as the range of 256 colors), while it means “8-bit per color channel”, which means that the presented JPG file has the True Color depth (8bit per Red, 8bit per Green, 8Bit per Blue = 24bit = 2^24 = 167772216 colors).
The presented EXR file has in fact higher color depth, but these “32bits” in the Photoshop means not the True Color (as the Author suggests), but much more: 32bit per channel, which means 2^96 colors (I will not show this number in the decimal form, because it would be too long). That’s why the EXR file contains more detailed information, as it is shown in the further part of this video
Cool! I didn’t know about this, always learn something new each day.
Thanks for your comment! I think I didn’t speak clear for this, sorry for that. I first mentioned the color mode in photoshop which showed 8bit/channel, then I went to explain ture color coz this may make clear for color depth. And you are right, that is definitily not for pixel but for channel. If you need more details you can check this link for 8~16~32bit/channel in photoshop ( goo.gl(/)gq0Z9 ) and this link for furthur information for 8~16bit/pixel color support in Photoshop ( goo.gl(/)neQRV ) :)

Pink Browser? Great Video nevertheless. ;)
that is my girl friends’s laptop, never mind plz :)
Hi everybody;
Witold Jaworski:
Sometimes the meaning of 32bit is 8bit->Red 8bit->Green 8bit->Blue 8bit->Alpha
in fact for more details you should use 32bit Float instead of 32bit Integer
thank’s for this tutorial :-) . your english is verry easy to understain (good for me).
Y modifie all my video clip (all made in blender)
http://www.youtube.com/watch?v=6zWqzMgAJQY&feature=youtu.be
is really better than the previus version with no correction..
thanks Ethan
That’s all very nice but how do you get Blender to display accurate colors in the first place? I have a hardware calibrated display (calibration done using Xrite Eye One) and Blender render output is way off compared to programs that support color management (Adobe products, Corel…).
If you can’t see accurate colors, what’s the point of correction.
I agree that, there just give you simple tools and panels to get the details. Even no number beside the Y axix.

This video graphs the gamut and color space of cameras. Still very useful in understanding color overall and it’s nice to see the colors plotted out.
