In the last video, we looked at the Lasso tool, which is a freehand tool for making selections. And depending on the object you're trying to lasso with it, it can be the perfect tool, but sometimes it starts to get a little touchy. And just by way of introduction, I will use the Lasso tool quickly and just make an obvious mistake here. If I'm drawing with this and all of a sudden I let up, see what happened, it always will auto-complete. And so, that could be frustrating to people. A lot of people will go back and like oh Command+D or Ctrl+D, I have got to start over again.
Well, actually, oops! There I made a mistake, I didn't want. Actually, if that happens when you're in the Lasso tool and you get that, you don't have to restart. Just remember, you can hold down the Shift key, and I could continue on my way. So even when this isn't necessarily the best tool to do this, you do have the option of just adding to the selection, so that you do grow it into what you want. So that's one way to do it, but I am going to show you the Polygon tool now, and show you how much more facile it is at working with edges.
So let's go back to the same area here, and in this case I am going to click on the Lasso tool and hold it down, and there is where we see the Polygon tool. So I am going to get that. I am going to go down here and I am just going to click and I am going to drag out. You can see this is a rubber banded line, so each time I clicked down, I am creating a new line segment. And so I am just going to use this ability to kind of do a dot to dot selection by going around the edge, and just selecting these.
Now one thing you do not want to do is put these too far apart, especially on an object with a rounded edge like this. If they're too far apart, you will get a visible kind of poker-chipping style edge where you can see the individual facets. So when things are rounded like this, you want to zoom in and you want to do your line segments fairly close together and that will avoid the obvious appearance of faceted edges along this. And once we're done here, you will see like, how do I quit? There is no way to end this.
What you have to do is hit the Return key, and now I've got my finished element. So using Polygon tools is a far easier way with respect to certain types of imagery to be able to make that selection. In the next video, we are going to take a look at the Magic Wand tool which is another way to select an image area by color, and it also works for certain types of imagery that you may work with.
