Join Timothy Sexton for an in-depth discussion in this video Working the contrast, part of Photoshop Retouching Techniques: Faces.
…Let's take a look at this contrast curve and get…into its structure and the strengths of this powerful tool.…So, let's double-click it.…And as we've established, this is our shadow point, this is our…three quarter tone, mid tone, and this is the white point up here.…The same applies for all these RGB lines as well.…These are red, green, and blue. CMY, cyan, magenta, yellow.…So if you go into…the red, and you pull down on the three quarter, adding density…to the image, you can see how cyan falls across the image.…
If you pull up on the quarter tone, you can see how the image fills with red.…Going down to the green line, if we pull down on the density.…The image starts to fill with magenta. And pulling up, it fills with cream.…And same thing with this blue down here.…When you add density, it adds yellow. And when you pull up on it, it adds blue.…When you're setting up your contrast.…You want to avoid putting more than three anchor points on a curve because when you…put too many anchor points on a line,…it'll cause the image to color band on press.…
