Learn about how to make more complex selections involving difficult areas, like hair strands.
- [Narrator] So in the previous movie, we refined a selection and we output that to a layer mask. So what is a layer mask? Well, here's one down here in the layers panel. It's attached to the current layer here and you can see there's a whole lot of black in there with some areas of white. And here's a simple rhyme for you to remember, black to conceal, white to reveal. So wherever in the mask there is white, you can see the content of the layer.
Wherever there is black, it's obscured, 'kay? You can even paint inside the mask. The only thing you need to be aware of is to make sure that it's highlighted like so with these borders. You see if I click on the layer, if I painted now, that paint would add to the layer. If I click on the mask, then I'm working in the mask. If I just get my brush tool here, B for the brush tool. I'm just going to choose a really simple brush from up at the top here. Yours might vary from what I've got here. I choose a brush here and you can change your size either with this selector here or using the bracket keys on your keyboard.
The right bracket makes it larger. The left bracket makes it smaller, 'kay? And I'm just going to paint down this area here. Now can you see what's happening there? There's white being added on there, or you would think so, it's not. It's that I'm painting with white and white reveals. So I'm just going to undo that, command zed. I need to come over here and swap my colors over. You can do that with the X key by the way, if you want to become a shortcut ninja, and then I can just paint down. You can see that line that was there a moment ago, that's disappearing.
In fact, I was using a brush that was slightly lower opacity and there you go. There we are. And I can just brush down those edges and away goes all of that extra content. You can see here there's some small dots in that area there, showing content through, so I'm going to get the lasso tool here and make a very, very crude selection because that's what this tool is actually for and then I'm going to fill that with black. If I go to the Edit menu and choose Fill, down to Content Aware and change that to Foreground Color because black is the foreground color at the moment.
Hit OK. You can see those white gaps have disappeared on the mask. I can now deselect that. So let's place another image. This time we're going to place an embedded image. We're going to bring in all the data. So choose Place Embedded from the File menu and from the exercise files, choose climber.psd and then resize this. So I'm going to use my Photoshop skills up here for transforming, so I've clicked on the lock there, and then I'm going to use staple accident finger or scrubby sliders as they're called or scrubby dragging to just make this a lot larger like so.
And then I'm going to reposition that down to about there. I think that's a pretty good composition for that. Double-click to apply it. And then over to the toolbox, if you tap W on your keyboard, it will get you in the right region. Long press on the magic wand and choose the quick select tool because selecting this walker or climber using that tool will take ages, but with the quick select tool, all you need to do is stay away from the edges. Just brush downwards like so and you'll see that, very quickly your selection grows as the quick select tool analyzes the surrounding pixels.
Don't go to the edges of the hair. Stay away from that. Just get the main body of the hair. Now go up to Select and Mask as we used in the previous movie, so choose that and again, make sure that you've got onion skin on because there are a range of different ways you can preview this. We're going to dial in a little bit of a radius. If you want to, you can click Show Edge up here and then dial up your radius and you'll actually get a preview of the radius that Photoshop will be using to analyze.
And we're going for something quite big, just here, about sort of, maybe not as big as that. Maybe down to about 15 pixels there. Turn on Smart Radius and it will deal with the edges slightly differently. We can now turn off Show Edges. And that's done a pretty good job of improving that straight away. If I drop down the transparency slightly here, you can see where those fine hairs are, out to the side. We're not going to use the global controls. We're going to use this, the refine edge brush, over on the left hand side.
You need a brush that's not too big and not too small. So I'd say around about this sort of size, just a bit larger than the edge, and then just brush on the edge. Don't brush into the main body of the hair and then brush around the wooly cap, just there because there will be little strands of hair there and just down into this region here and actually just on the edge just there. It'd be a good shot there I think. Perfect. Let's push up that transparency on the side here and that's done a pretty good job of refining that selection.
Now the hairs here look a bit thick and dark. What we need to do is kind of decontaminate those colors and that's something we can do here in the output settings. As soon as we choose it, it will jump to creating a new layer with a layer mask and if we hit OK, you'll see that it's turned off our existing layer, but it's kept it, so we've damaged nothing in doing this and we've got a mask attached to this. And that hair blends pretty well with the background, very quick, very good heal there.
I think I'm just going to remove this layer here. So I'm just going to click on it to make it active and then hit the trash there to get rid of it. We don't need it. In the next movie, let's change some colors.
