Selection tools are really the heart and soul of Photoshop because without a selection you can perform an operation and affect your entire image as opposed to a specific area. Think of this way a selection is like a force field and whatever is in that force field is the area that is going to be affected and everything else will be protected. So let me go ahead and show you what happens if you don't make a selection. And by the way this upper area of our tools are where the selection tools live. Ok? So I'm going to grab a filter, I'm gonna grab my wave filter, and as you see here I am in my distort area and I have the wave which was the last filter that I used. But I'll go up to the store anyway and choose wave again and I'm gonna click OK. Since I didn't tell Photoshop to protect any portions of this image the entire image is hit by the big wave. So I'm gonna undo that and now I am gonna grab one of my selection tools and I'll talk about what these do in a minute and I'm just gonna draw, let me grab the elliptical one here, and I'm gonna draw out a selection and he does have a big head doesn't he? nd now I'm gonna do that same filter and look what happens. I tell Photoshop to affect only what is inside this boundary and leave everything else alone. So that is what a selection will do for you and that's why their so powerful and that's why you really have to understand how to use them. Anytime you want to get rid of a selection or marquee or any of those tools you use, go to select, de-select or press command or control D. Alright? Now just alittle background about image, I was always a big Charlie Brown fan growing up and uh I read all the books and I figured what happens if Charlie Brown grows up and becomes a cool super spy like James Bond and this is what this image is. His name is C. Brown so he's really gown up and he's cool and he's tough and nobody is taking that football from him anymore. So now the rectangular marquee tool will allow you to draw a rectangular marquee and you can move your mouse and do all kinds of stuff like this to select the area that you want to place it. And once you have it the selection, you can put your mouse in here and then move that selection around so you're never really stuck. Let me deselect that and I am gonna show you that if you hold down the shift key what you'll get is a perfect square, the same holds true for the elliptical marquee tool as well. What you'll also notice is that when you have this tool selected you can choose how the marquee is going to work. For example I can choose a style where there is gonna be a fixed ratio, a fixed size and then I can enter the dimensions myself. So I can say 200 pixels here and I can say for height 200 pixels and then when I draw it's gonna give me exactly that. Nothing more, nothing less. If I want to go back I can go back to normal and then I can draw my own marquee again, so let me go ahead and just draw out my own size. The other selection tool we have of course is the move tool and the move tool will move whatever is selected in this case I have this selected here. Which again you notice something very interesting, as opposed to grabbing the marquee tool where the icon is in marquee, see the little marquee under the mouse, if I grab the move tool I get a pair of scissors. Guess what's gonna happen? It's gonna move the selection and what's inside of it. Watch this, see that? So I am actually moving that object around. I cut it out and moved it around. So be careful with that, if you just want to move the marquee grab the marquee tool. If you wanna move the contents grab the move tool, OK let's deselect that as well. We also have our polygonal lasso tool, our lasso tool and magnetic lasso tools and these are really, really cool and I'm gonna spend some time talking about how those work but very quickly I'm gonna show you that with the lasso tool you can draw your own shape and then fill it in with a color or whatever you want to. So you have full control over that, that with the lasso and we're gonna talk about that later on. We also have our crop tool which I talk about in another movie and we also have our quick selection tool and magic wand tools which I'll go more in depth with as well. So once again the main benefit to a selection is that you're able to tell Photoshop specifically what portion of image you want to effect as opposed to affecting the unselected or the entirely selected parts of your image.
