Now this segment here is going to be a little bit advanced, but I just want you to have these tools available to you. So you might want to go through the training series, and then come back and use this segment as a constant reference. So I am going to close this image here, Polygonal Stairs. I am going to double-click the background to open up pumpkinhead.jpg, and hit Open. Oh, that's just the cutest thing ever.
So let's go over here to the Tools palette, and I am going to select the Elliptical Marquee tool. Again, this is the second one down here, and I am going to give you just a smattering of keyboard shortcuts that work with the Selection tools. These are awesome keyboard shortcuts. Again, it might be a little sophisticated, a little advanced for right now. So you have already come back to this one, but these are just some great shortcuts to make these tools so much more valuable.
Now, if I were to select this pumpkin head, just click and drag around and now basically that pumpkin head is selected. There are some stuff on here that's not selected, some stuff over here that's not selected, and this isn't the greatest selection in the world, but you get the idea.
Now what if we wanted to select both of these pumpkins, both the evil happy face, and the death skeleton pumpkin as well? If I started clicking to drag the select around this, the default behavior is that it make a new selection getting rid of whatever selection was there before. So if I want to make both areas selected, I could, before I started clicking to make my second selection, hold the Shift key.
Now, look at my cursor. If you look really closely, there is a little Plus (+) icon that pops up while I am holding the Shift key. What that indicates is that I will be adding to the selection. So the cursors in Photoshop really tell a story. They really do tell you a lot about what you are about to be doing and in this case, if I hold Shift, it's telling me that I will be adding to this selection.
Now, if I hit Shift and add to this, there is now one big selection area that we can fiddle with. Now, this opens up a whole new bunch of doors. Say, for example this outer lip. We could go in and just hold Shift and add to this selection, and just keep doing that over and over again until our entire area is selected and this isn't very effective for this entire image here, but this does work a lot for me, when I have just a little bit of something that's hanging on there I want selected or not selected. Sometimes I will just go in with the Marquee tools and/or hold the Space-bar and transport that selection over and fill that completely like that.
Again, the spacebar will work to move a selection. Let me hit Ctrl+D to deselect this, and I will show you an example just using the spacebar. If I click and drag to make an Elliptical Marquee selection, and while I am holding the mouse, again, once you let go off of the mouse, it's all over folks. So if you want to do these cool keyboard shortcuts, you have to be still holding down the Mouse button.
So again, while you are holding the Mouse button, you hold the spacebar, and then when you move the mouse, it doesn't resize the selection, it moves the selection around. That also comes in handy quite a bit. So I am going to let go of the mouse, and then let go of the spacebar, and now I am going to deselect that by hitting Ctrl or Command+D for deselect.
Let's pretend that I took a long time and made this a really good selection. Let's say I wanted to cut out the holes in the eyes just like the pumpkin head is cut out already. Well, what I can do, is use another selection tool, which is another great benefit of these Selection Tools is they are not mutually exclusive. You can use one for one part of your image, and then add to, or take away from that selection using additional tools.
So you could use any tool you want or alternate. It's totally up to you. So what I want to do is not add to this selection, because this area is already selected, what I want to do is cut a hole in this selection. The way I do that, is instead of hitting Shift, I hit Alt, and now look at my Lasso icon. If I hit Shift, I get a Plus(+), if I hold Alt, I get a Minus(-). Meaning, that whatever I select now, will actually cut a hole in, or subtract from the selection that I already have. So I am just going to hit Ctrl+D to deselect that.
