Step 2-Channel Selection You can modify tones for all colors in the image using the master curve, or select any of the red, green, and blue or cyan, magenta, yellow, and black curves for editing using the channel menu (see right; when grayscale is selected, only the master curve [L] is displayed). The histogram shows tone levels for the selected channel only. When the master curve is selected, the auto-contrast button and white-point and black-point eyedropper tools (see below) apply simultaneously to all of the component channels (the master curve is unaffected). When one of the component channels is selected, these controls can be used to edit the chosen curve only. The current channel can also be selected using the following shortcuts: • Ctrl 1 (Windows)/ 1 (Macintosh) Red channel (RGB)/Cyan channel (CMYK) • Ctrl 2 (Windows)/ 2 (Macintosh) Green channel (RGB)/Magenta channel (CMYK) • Ctrl 3 (Windows)/ 3 (Macintosh) Blue channel (RGB)/Yellow channel (CMYK) • Ctrl 4 (Windows)/ 4 (Macintosh) Black channel (CMYK) Reference:The Tool Chest 66

Step 2—Channel Selection
You can modify tones for all colors
in the image using the master curve,
or select any of the red, green, and
blue or cyan, magenta, yellow, and
black curves for editing using the
channel menu (see right; when
grayscale is selected, only the master
curve [L] is displayed).
The histogram
shows tone levels for the selected
channel only.
When the master curve is selected, the auto-contrast button
and white-point and black-point eyedropper tools (see below)
apply simultaneously to all of the component channels (the mas-
ter curve is unaffected).
When one of the component channels
is selected, these controls can be used to edit the chosen curve
only.
