Shades of gray partially hide, depending on the gray levels (255 is the value for black, hiding artwork completely 0 is the value for white, revealing artwork completely). As in life, rarely is anything black and white. You use the Channels panel to view and work with alpha channels.Ī key concept in masking is that black hides and white reveals. Photoshop also uses channels to store an image’s color information. In Photoshop, you can make temporary masks, called quick masks, or you can create permanent masks and store them as special grayscale channels called alpha channels. In addition, you can use masks for other complex editing tasks-for example, to apply color changes or filter effects to an image. With masks, you can create and save time-consuming selections and then use them again. When you create a mask based on a selection, the area you haven’t selected is masked, or protected from editing. Photoshop masks isolate and protect parts of an image, just as masking tape protects window panes or trim from paint when a house is painted. You can create a temporary mask to use once, or you can save masks for repeated use. The cutout portion of a mask can be altered, but the area surrounding the cutout is protected from change.
