The Lasso Tool allows you to cut part of an image out.

To phrase that more technically, with the lasso tool you can create an active region in whatever shape you like.

Image Sandwich:
Setting one layer between the background layer, and a duplicate of part of the background layer to make it appear as that in between layer is behind an object in the image.

  • Understanding the Basics - goes over how to navigate the interface, basic shortcut keys, adding text, working with images, and other features to get you up and running as quickly as possible.
  • Layers - shows you how to combine multiple images, resize them, split them apart, and add in color boxes.
  • Selections - starts by showing how to remove simple images from a photograph and finishes by showing how to select out strands of hair and change the background.
  • Color Correction - goes from simple corrections to in depth theory. It uses this theory to fix complicated photographs, change the color of a shirt from yellow to green, and even turn part of an image into black and white.
  • Object Removal - isn't just about how to remove a pimple. It covers removing wires, large objects such as a fencepost, and even how to get rid of something like a date stamp when it is in front of a person's face.
  • Beauty Retouching - I show you how to remove wrinkles, increase the size of an eye or decrease your nose size, how to smooth skin, what to do if you make a mistake, and how to fix problems such as bloodshot eyes.
  • Compositing - you see how all of these individual tools we've learned along the way can actually be combined to accomplish just about anything, from merging together household goods to to removing a person from a photograph and putting someone else in that person's place.
  • Wrap Up - shows how this is a solid grounding and while there's still plenty to learn, you now know enough to be dangerous.
English So let's say that I wanted to put this duck behind the Sandu. Now in order to do that what I would have to do is I would need to cut this sand dune out put it in front and in that way habit so the duck is behind it. So I'm going to introduce the Lasso tool the way the Lasso tool works is you click and then every time between each of these clicks. So you can see that I just kind of keep clicking every time between each of these clicks or line forms and it works exactly like a pair of scissors and my exactly like a pair of scissors. I mean it's not sharp but you can't cut yourself on it but you're able to. It's nothing like a pair of scissors. That was just an analogy they use the word exact was inexact. Don't worry about it. So I'm going to do is I'm going to click until I get to that original point and when I get to the original point I just double click and that creates an active region in whatever shape I want. Then all I'm going to do is I'm going to hit control-C to copy and you'll notice could not be copy because it's on the wrong layer if ever there is a problem. The first place to look is are you on the right layer. In this case we can see that the duck layer is selected. In fact let's call this duck and the do layer's that's like. So if I go to dooen press on it and then hit Control C and then control V to paste it pastes right here . Now we're running into a problem and that problem is that it didn't paste exactly where we wanted it to. Instead it kind of moved it over to the left a little bit. Let's undo that and instead of just pressing control V to paste what I'm going to do is I'm going to go into Edit Paste Special and go to paste in place and now will paste directly there. Now it looks like nothing has happened. Jeremy you didn't paste it at all things you did nothing. This is embarrassing what an embarrassing teacher you are. You have accomplished. Stop making fun of me. OK. Just stop it. OK here's what happened. It was really what happened was it pasted it paste of the layer but because it is directly on top of the other layer. You can't see that that's happening. So I can actually move this right here and there is there's two layers here only because it's the same thing and it's directly on top of it. You can't see so now if I move this dock here while nothing's happening but if I sandwich it between the layer and itself you can see that it's now ducking out peeking out behind the mountains. Now you can see that there's this little blue line that we don't want right here. So in order to do to get rid of that I'm just going to go into this Lasso tool and I'm just going to go a little bit further deeper to make this happen. Those of you who have used Photoshop in the past probably know there's a few better ways to do what I'm showing right here. Don't worry he'll be showing that later. All right and I'm going to press delete. In order to delete everything in the active region. Now notice what happened isn't what I wanted. Whenever there's a problem the first place to look is if you're on the wrong layers. Let's undo that. And I can see that I'm on the Duck layer and I want to be on the dooen layer so I'm going to hit delete . And again what I wanted didn't happen. I want to get rid of that blue lane. Instead I deleted out from the dune layer not what I want from the bottom layer as opposed to the top layer. So I'm going to go here for delete. This time I'm on the right layer. De-select just by clicking. And it works. Giant Docky is there. So that looks pretty good. And those are the basics of the Lasso tool.
