This may help you out also.

Photoshop uses special grayscale channels to store an image's color information and information about spot colors. If an image has multiple layers, each layer has its own set of color channels.
Color information channels are created automatically when you open a new image. The image's color mode (not its number of layers) determines the number of color channels created. For example, an RGB image has four default channels: one for each of the red, green, and blue colors plus a composite channel used for editing the image.
You can create alpha channels to store selections as 8-bit grayscale images. You use alpha channels to create and store masks, which let you manipulate, isolate, and protect specific parts of an image.

Ask more if you wish.
