"Adobe Photoshop is a registered trademark of Adobe Systems Incorporated, and I am in no way affiliated with Adobe. So in this tutorial, I'm actually going to be talking about another way of actually doing this color inverse deal that I've been doing. So you hit File - Browse. I accidentally hit Browse. Hit File - Open, and it's actually going to bring up my Bridge software here in just a second, so I'm going to have to click out of that. I'm actually going to use the image that we did yesterday, which is going to be this one. Ok. So now you hit the F key to make it a full-on document like I have right here. Ok, so this is the one I did in a different tutorial, and we're going to use this one for several reasons. One reason is we're going to want to change the sky here in just a second. But what you want to first do is open your document, and you want to unlock your document. So double-click on the background and name this one. And as you can see, my Bridge came up because I accidentally hit Browse, so click out of that. Ok. So I'm actually going to hit - I'm going to rename this "Master" and hit OK. And I like to duplicate my layers a lot of times, so Copy Command or Control-J. So we have two different layers just as a reference. So we're going to work on the top layer here on this one. And I'm actually going to show you on the next tutorial exactly what we're going to be doing. But for the most part on this one, it works best if you're trying to change the sky color. So I'm going to actually show you that here in just a second, but the reason why I'm using this as a clip is because I wanted to show you that you can actually do this with the sky and make it look a whole bunch better. So on the next tutorial, I'm going to go more into detail about what we're trying to do here."
