Cutting a Simple Mask
I say "cutting" because in the old days they used to cut frisket or rubylith to indicate areas that were to be silhouetted or shielded. Digitally speaking, cutting a mask is the same as making a selection. I'll outline the steps below in Photoshop:
- Using an organic selection tool such as the Magic Wand, select
the area to be masked. In this case, the subject is to be isolated and
the background will be masked. Keep the Magic wand Options palette open
and adjust the tolerence as necessary to make a clean selection.
TIP- in many cases, it is easier to select the main object and choose Select>Inverse to invert the selection from the subject to the background.
- You should now determine the purpose for your mask. In this case, we will
delete the active area to create a silhouette, although we could have used
it to define an area for further editing? If you're creating a silhouette,
you may choose press the delete key and be done with it, although you should
probably take a few extra steps.
- In many cases a silhouetted object will benefit from a feathered edge.
An anti-aliased look integrates the images with the background and hides
and rough areas that may have been hard to select. In addition, if you are
doing further editing, feathering is essential to help the edits blend with
the rest of the image. To feather the
selection, choose Select>Feather and specify the number of pixels to
be used. Keep the overall image size in mind as you specify the feather
- Press the delete key to delete the
background and be done with it.
