| Re: Question about D&B It is not necessary to use a layer mask on a D&B layer (50% gray set to one of the 7 blend modes in which 50% gray produces no changes). In effect the 50% gray acts like a mask.
D&B layers are typically used for selectively dodging and burning specific spots or areas of an image. They are also used where the adjustments are typically not extreme.
For global changes it is often more efficient to use Shadow/Highlight, Curves, levels, etc and with or without a layer mask.
Like everything else in Photoshop, there are often many tools, adjustments, and work flows used to achieve the exact same end result.
