Add Alpha Channel = enable transparency
No alpha channel means there cannot be transparency
If you add a transparent layer then there is transparency ie there is an alpha channel
If there is an alpha channel, transparency can be set between 0 and 100%
0% = transparent; 100% = opaque
If a layer is white there are 2 possiblities
1) There is an alpha channel; but opacity (transparency) is set 100% so it is not transparent
2) There is no alpha channel so there cannot be transparency
Layer masks are used to control the transparency. Portions of a layer can be made transparent or semi-transparent; other portions of the same layer can be opaque.
