Smoothing a badly stroked edge

- In this movie, we're going to fix…these horribly stroked edges here,…using the Refine Mask command.…Now, the reason they look so very awful,…as you can see here,…and we've got these sort of little puddles of paint as well,…is because we're trying to stroke some soft edges.…And to see what those edges look like,…you can press the Alt key,…or the Option key on the Mac,…and click the Layer Mask thumbnail for that effect layer.…And now, notice all this softness…that we brushed in using the Smudge tool.…Well, basically what Photoshop is trying to do,…is stroke all of those soft pixels,…and you can see what that looks like…by Alt clicking or Option clicking…on that Layer Mask thumbnail once again.…

So, in some places we get a blurry stroke,…and then other places we get these blobs,…and these blobs, by the way,…are caused by single pixels of brightness…inside of the mask.…And the best solution for getting rid…of all this stuff is Refine Mask.…And the reason is it gives us the option…of both smoothing out the edges,…and increasing the contrast.…
