3 Apply sharpening by doing one of the following:

– Using that node’s contextual menu, uncheck Enable Channel 2 and Enable Channel 3, which

correspond to the U (Cb) and V (Cr) channels, leaving only Channel 1 (Y) enabled. Then, open the

Blur palette, and drag the ganged Radius sliders down to sharpen the Y channel.

– You can also just open the Blur palette, ungang the Radius sliders, and drag the red slider down

to sharpen the Y channel, since any control with three gangable sliders will automatically assign

those sliders to whichever channels are used by the currently selected Color Space.

As you can see, while the Blur palette ordinarily provides separate R, G, and B controls that can be

unganged from one another, the Color Space submenu lets you apply sharpening to the channel

definitions of other colorspaces, providing many other corrective and creative possibilities with the

same controls.

Supported Color Spaces for Conversion

The Color space submenu available when you right-click a node in the Node Editor supports

four different color spaces that you can set each node to work within. When you choose a

color space other than RGB, all channel-specific controls (the Custom curves, Soft curves,

RGB Lift/Gamma/Gain sliders, and RGB mixer) operate on the particular channels of that color

space, rather than the default YRGB channels. By switching color spaces, you can achieve

very different kinds of adjustments by swinging values among mathematically different axes.

YUV converts the image into Y’, Cb, and Cr channels. The Y’ channel governs luminance,

while the Cb and Cr are color difference channels that work within the broadcast

model of color.

HSL converts the image into Hue, Saturation, and Lightness channels. Lightness is identical to

Luminance, while Hue and Saturation are exactly as described.

LAB operates on the L, A, and B channels. The L channel governs luminance, while the A and

B channels are color difference channels; A adjusts color on an axis from magenta to green, B

adjusts color on an axis from yellow to blue.
