Lesson 10

Lightroom, Channels, Masks and NDE Cont.

Photoshop – Channels and Masks

Every Photoshop image has one or more channels, each storing information about color elements in the image. The number of default color channels in an image depends on its color mode. By default, images in :-
• Bitmap, Grayscale, Duotone, and Indexed Color mode have one channel;
• RGB and Lab images have three; and
• CMYK images have four.
Channels in color images are actually grayscale images that represent each of the color components of an image. For example, an RGB image has separate channels for red, green, and blues color values.
There is also a composite channel used for editing the image.
