My RGB Curve node looks like this: my RGB Curve

But on most of the tutorials it looks like this: their RGB Curve

They have the black and white channels. I upgraded from blender 2.77 to 2.78, and I tried toggling between cycles render and blender render. How do I get the node they are looking at?

    $\begingroup$ You are totally right, when I go to compositing view (instead of expanding new windows in default view), I get the second node. Thank you! $\endgroup$ – James Johnson Aug 5 '17 at 6:46

  • $\begingroup$ @Cegatron I think that you should make this reply an answer for others with the same confusion ;-) Thanks ray-maillot for the tip although I can't @ you in same reply $\endgroup$ – 3pointedit Aug 6 '17 at 1:25

The first image is from the material nodes.

The second is from the compositor nodes.

The curve editor in the Compositor works differently, it has additional controls to determine the ranges for the curve.

From the Blender Manual:

Black Level

Defines the input color that is (linear) mapped to black.

White Level

Defines the input color that is (linear) mapped to white
