Using ColorSaturation

The ColorSaturation process, under Process – IntensityTransformation, is used on nonlinear images when you want to modify the color saturation based on hue. ColorSaturation preserves color balance allowing you to make adjustments freely.

This process has a Real-Time preview so that you can get immediate feedback on your changes. You use ColorSaturation to define points on the chart on the upper part of the interface. The line going through the middle is the zero point at which no change to the image occurs. The lines above and below the zero point either increase or decrease saturation based on where you place your point.

You can drag the whole line up or down by clicking the small circle on the left side of the graph.

You can change the type of graph you make by clicking one of the three interpolation buttons on the right. In the preceding screenshot, I’m using the linear interpolation to deemphasize the green and boost the blue parts of the image. You can use the real-time preview to get immediate feedback based on your settings.

If you run out of room to increase or decrease saturation, increase the Range parameter to give you more range (in this example, the Range is 3).

You can adjust the hue along the bottom of the graph by sliding the Hue shift slider.

When used in conjunction with the ColorMask script, for example, you can target specific areas for changes in hue to, for example, shift from an orange-red to a more red tone using this process.
