Blending a Smart Object into a photograph

In this movie, I'll show you how to blend the tattoo in with the flesh of the arm.…And I'll also show you how to blend away these…little bits of flame that are extending beyond the arm.…And this will serve as a kind of advanced preview of…the sort of blending options that we'll see in a future chapter.…So, for starters here, you want to double-click…on an empty portion of this layer…here inside the Layers panel, in order to open up the Layer Style dialog box.…I'm going to go ahead and move this dialog box off screen, and…also zoom into the artwork by Ctrl+Spacebar or Cmd+Spacebar clicking.…

Now, notice this slider bar that's labeled underlying layer.…It extends from black over here on the…left-hand side to white over on the right-hand side.…And we also have luminance values of 0 for black and 255 for white.…What we can do by modifying these slider triangles,…is force through luminance levels from the underlying layer,…so that they become visible, and the pixels on…the active layer on top of them become invisible.…
