Are you ready to go and clean up your selection? Well, I kind of need to let you in on something here. Your saved selection, I need to let you know where it's stored and I need to let you know what it's called. It's actually referred to as an Alpha Channel here inside Photoshop. Have you ever heard of Alpha Channels before? Well, they're additional channels that are actually stored inside Photoshop's Channels Palette, which might seem a little odd or a little unlikely but let's go and take a look here. I'm going to head up to the Window Menu and then all the way down to Channels to pop open my Channel Palette and of course inside the Channels Palette I see a composite channel at the top here, RGB and then I see individual color channels; red, green and blue and then as odd as it may seem, there is an extra channel down at the bottom there called Blue Truck, the selection that you and I had saved out and if I want, I can click on this little box here over on the left-hand side to turn on the Alpha Channel and the Alpha Channel appears inside Photoshop as this red, rubilith overlay, almost like Photoshop's Quick Mask Mode. See how everything kind of fits together here, right? So check this out. Here's what I'm going to do. I'm going to turn off my composite channel all the way at the top there just by clicking on his Eyeball Icon and I'll move my Channel Palette out of the way and now what we get is our Selection or our Alpha Channel in pure black and pure white. Now, what's really cool here is I can actually paint on this using Photoshop's Paintbrush Tool. I'll head back to the Paintbrush Tool and what I want to make sure of inside the Channels Palette is that the Blue Truck Alpha Channel is actually selected, so we might have to click on it from there and what I can do here is I can paint in black if I want to subtract from the selection and add to the mask here that I see or what I can do is I can hit the X Key on my keyboard and now paint in white to subtract from the mask and thus add to the selection, right? So it's just another way to work. What I'd like you to do is just take moment with your Paintbrush Tool. You might have to crank up the size of your Paintbrush Tool as well by the way and what I'd like you to do is go ahead and clean out sort of the insides of your truck, if you know what I mean; all the black areas inside the center area of your truck. Go ahead and clean them all out, something like this. Now, while you're doing this you might need to zoom in just a little bit, something like this and possibly increase or decrease the size of your brush. As I say, I'm sure you remember how to do that, your Square Bracket Keys on your keyboard, right? Something like this. So this is how we can edit an alpha channel by the way. We're editing directly on the alpha channel. And by the way, what's cool is not only do I want to make sure that the insides of the truck are pure white but I want to make sure that the outsides of the truck are pure black. I can see I have some white flecks here on the outside of my truck so I'll just hit the X Key here and I'll make sure to fill them in with pure black, right? That's sort of the idea here. We want to come along and make sure that all of this is cleaned up. So hopefully within just a few minutes we should have a perfect selection for our Blue Toy Truck inside our photo, inside our image and what's great is once we have this selection complete, then we can do any number of things to our toy truck. As I had alluded to much earlier on in our exercise here, we can certainly apply some Photoshop filters. We can certainly apply some color correction if we want or color effects to our toy truck or maybe we want to pull him off as background and use him as a web layout or something like this, right? Maybe you're building a banner ad or something like this for a website that is selling toy trucks or toy truck-related products, this kind of thing, right? So this is really what it's all about. Whenever I teach Photoshop, this is usually one of the number one questions: how do I pull an object off of its background? Well, we're getting to it. This is kind of the first step anyway is isolating that object away from the rest of the image, right, something like that. Alright, perfect. So now that I have a perfect selection here, I'm going to hit the V Key to go back to my Move Tool. I'll go back to my composite channel inside the Channels Palette, the RGB Channel there and I'll go ahead and turn off the Alpha Channel and now I can go and reload the selection. Now, you saw already that I can go up to the Select Menu and choose Load Selection. That's one way to load in your alpha channel or one way to load in your saved selection. Here's another way and I love showing this. Give this a try. Inside your Channels Palette, hold down Control on the Windows side or Command here on the Mac and click on your Alpha Channel Thumbnail inside your Channels Palette and that'll load in your marching ants. So there you go. There's how you can go about working with and perfecting your Alpha Channels here inside Photoshop and how to work with Photoshop Selection Tools as a whole.
