within the adjustment layer, which acts as a veil through which the underlying image layers appear. You must use
Photoshop to create and edit adjustment layers; however, you can view existing adjustment layers in ImageReady.

Correcting in CMYK and RGB
Even though you can perform all color and tonal corrections in RGB mode and nearly all adjustments in CMYK, you
should choose a mode carefully. Whenever possible, avoid multiple conversions between modes, because color
values are rounded and lost with each conversion. If an RGB image is to be used on-screen, you don’t have to convert
it to CMYK mode. Conversely, if a CMYK scan is to be separated and printed, you don’t have to perform corrections
in RGB mode.
