Using the Color Correction Compositing Node in Blender

Learn to use the color correction compositing node for fine tune control

The Color Correction node allows you to adjust the highlights, midtones, and shadows of your render to perfect the final result. However, it is much more than just adjusting a few sliders and gives you a lot of power.

This tutorial gives you a detailed explanation of each aspect of the Color Correction compositing node. Introducing Gain, Gamma, Lift, and Slope, Power, Offset color grading algorithms.

If you’re new to color correction, color management, and compositing in general then I highly recommend you check out our Compositing in Blender training series.

    great stuff bartek,really enjoy your tutorials,very clear,I am the “2nd” kind of artist who likes to know what things do.Was waiting for this,was sad that it wasn’t included in the compositing dvd,but I think the dvd was made just before this node was added.

    It would be nice if you could go through an explain the cycles nodes and what they do,just like you did in the free composting tutorials and dvd,but I guess your expertise lie in the compositor.Just an idea for future free/citizen/dvd tutorials…

    Very useful bit of information–I might even find myself using the color correction node more, now that I understand it better. :D

    Hi Bartek,

    Just wanted to say that your teaching style is one of the best I’ve EVER seen. Thank you very much for your tutorials. Your DVD about compositing is also a masterpiece.

    The names make no sense at all, but this is great for some fine tuning work.

    Any chance for some more Blender->After Effects Tutorials from you? :-)

    Awesome. Bartek, I love your tutorials; you’re so thorough in your explanations. Keep up the great work!

    Where are histograms? It’s almost impossible to talk about color correction without seeing them!

      When you view output in image editor, you can hit “T” and you have histogram, scopes and all other useful stuff. In this video I didn’t focus on that. I only wanted to analyze one single node. It’s not the tutorial about color correction, but about “color correction” node.

        Don’t get me wrong, I appreciate your effort in explaining this, but you can’t seperate color correction from color correction tools, and node is a tool. This is a tutorial for people who maybe have never before used color correction and don’t know what those parameters do.. and visual feedback – histograms, is a “must have” thing to understand what exactly happens when you move a slider. It’s much easier to understand things if you have visual feedback.
        It would have not been hard to hit that “T” and at least leave it opened if not explain them.
        ;)

    Bartek, you are the best. Compositing in Blender is absolutely amazing. The information that includes can be used beyond blender as I now apply this knowledge in After Effects too. Seriously you should consider publishing a book and a sequel to Compositing In Blender. Thank you.

    Regards.

        I clicked on color and color correction isn’t there. I am using 2.65a I’ll just get it from the link you posted thank you

        This is NOT a material node, but a COMPOSITING node. Take a look at the blue outline in the image I linked to. This shows that we are working in compositing nodes, not material.
        Render Engine doesn’t matter here.

    I’ve always wanted to be able to reverse the color correction node. I can do it with three separate color correctors, adjusting the gamma, gain and saturation, for example, then putting other comp nodes in between, and finally adding three more color corrector nodes with reciprocal vales in saturation, gain and then gamma, reversing the original correction.

    Why would I do this, you might ask? Sometimes I get footage in log color, shot on an alexa, RED camera or my Blackmagic Cinema Cameras. Applying a neutral grade at the start of my comp, doing the rest of the comp and then returning the whole thing to it’s original color for DI is how things are often done in the professional world of VFX.

    Blender does not make this easy at all. I could make a group node, but can’t figure out if it is even possible to expose the color corrector individual values to the inputs or outputs of the group.

    Any help, Bartek (or anyone else)?

    I might add, there is a separate gamma node, but no nodes for saturation, lift, gain or contrast. If that were the case, this would be a simple matter.

    And a LUT importer that could take me from Alexa log, or RED log, or whatever to Rec.709 and back would be nice.
