layer mask. Black which will make the layer totally transparent,

White which will make the layer totally opace or the alpha channel
|
|
of the layer. When you choose the alpha channel the transparency
|
|
of each pixels will be mapped to a grayscale value in the mask. If
|
|
you want to further manipulate the transparency in a layer this
|
|
can be a very good option (e.g. maybe you have softly erased some
|
|
parts of the image and want to continue to manipulate the
|
|
transparency).

> To paint on the layer mask you have to activate it, you do that by

clicking on the thumbnail image of the mask. However you will not

|
see the mask, you will just see the result of your mask applied to
|
|
the layer. To see the mask you have to <Alt> click on the
|
|
thumbnail. If you want to see you layer without the mask applied,
|
|
<Ctrl> click on the mask thumbnail. Remember to click once
|
|
again with the same modification key to exit the current "preview"
|
|
state.
