When a mask channel is selected in the Channels palette, foreground and background 
colors appear as grayscale values. (See 

“Creating temporary masks in Quick Mask mode 

(Photoshop)” on page 278

.)

Examples of masks: 

A.

 Opaque mask used to protect the background and color the shell

B.

 Opaque mask used to 

protect the shell and color the background

C.

 Semitransparent mask used to color the background 

and part of the shell

In Photoshop, you can create masks, all stored at least temporarily as grayscale channels, 
in the following ways:

•

Quick Mask mode lets you create and view a temporary mask for an image. Temporary 

masks are useful when you don’t want to save the mask for later use. (See 

“Creating 

temporary masks in Quick Mask mode (Photoshop)” on page 278

.)

•

Alpha channels let you save and load a selection to be used as a mask. (See 

“Storing 

masks in alpha channels” on page 280

.)

•

Layer masks and vector masks let you produce a mix of soft and hard masking edges on 

the same layer. By making changes to the layer mask or the vector masks, you can apply 
a variety of special effects. (See 

“Masking layers” on page 314

.)

Creating temporary masks in Quick Mask mode 
(Photoshop)

Quick Mask mode lets you edit any selection as a mask without using the Channels palette 
and while viewing your image. The advantage of editing your selection as a mask is that 
you can use almost any Photoshop tool or filter to modify the mask. For example, if you 
create a rectangular selection with the marquee tool, you can enter Quick Mask mode and 
use the paintbrush to extend or contract the selection, or you can use a filter to distort the 
edges of the selection. You can also use selection tools, because the quick mask is not a 
selection.

Start with a selected area and use Quick Mask mode to add to or subtract from it to make 
the mask. Alternatively, create the mask entirely in Quick Mask mode. Color differentiates 
the protected and unprotected areas. When you leave Quick Mask mode, the unprotected 
areas become a selection.

A temporary Quick Mask channel appears in the Channels palette while you work in Quick 
Mask mode. However, you do all mask editing in the image window.
