Where do I find the composite channel in Photoshop?

How are alpha and spot channels used in Photoshop?
Alpha channels store selections as grayscale images. You can add alpha channels to create and store masks, which let you manipulate or protect parts of an image. (See About masks and alpha channels .) Spot color channels specify additional plates for printing with spot color inks.
How are the color channels preserved in Photoshop?
As long as you save a file in a format supporting the image’s color mode, the color channels are preserved. Alpha channels are preserved only when you save a file in Photoshop, PDF, TIFF, PSB, or raw formats. DCS 2.0 format preserves only spot channels. Saving in other formats may cause channel information to be discarded.
