Performing selective edits with Dodge and Burn

In this exercise we'll selectively modify the contrast of the mask.…However, instead of using the Brush tool set to the Overlay mode, as we have in…the past, we'll take advantage of the Dodge and Burn tools, which give us even…more selective control.…And I have my final Merged iterations alpha channel selected.…Before we set in making modifications to it, I'm going to make yet another…duplicate by dragging and dropping it onto the little page icon, and then I'll…move it to the top of the alpha channel stack right there, so it's easier to get to.…So I don't have to scroll up and down this list so much, because this will be…our final mask, which is of course why I'm naming it so.…

I'm going to zoom-in on this knuckle here, and notice that it has a little bit…of a bounce above it.…However, it does need to be brightened, so if I went ahead and grabbed my Brush…tool, as I normally would, which is the quickest approach, by the way, I should…tell you that, so I'm not knocking this approach at all.…
