Starting to Work / Lasso Tool and Anti-Aliased Selections
Subtitles of the Movie
[00:00:00.0] Similar to the rectangular marquee tool, there is also a elliptical marquee tool. [00:00:05.0] And you can click and drag out elliptical selection shapes. [00:00:14.0] And of course (if) you hold down the Option key, [00:00:16.0] you will drag from the center, and if you add the shift key it will constrain it to a perfect circle. [00:00:24.0] There are a couple other marquee tools in this particular tool hidden down here - [00:00:33.0] the single row and the single column. This will select a single pixel row of selection. [00:00:42.0] So you can create a horizontal or a vertical selection of a single row of pixels. [00:00:48.0] The lasso tool allows you to create a free hand selection, and notice that looks like a little lasso. [00:01:00.0] So I can click and drag around an object and create a freehand selection. [00:01:09.0] And sometimes doing this, you might have to go back using the add or subtract selection tools to edit your selections. [00:01:17.0] And this would be quite difficult with the mouse, but I am using a pressure sensitive tablet and stylus combination. [00:01:25.0] Makes it a little bit easier to create the selection. [00:01:29.0] So again, I'm going to want to add to the selection by holding down the shift key, [00:01:33.0] and notice now that my lasso tool has a small plus next to it. [00:01:37.0] I can begin to perfect my selection this way. [00:01:41.0] And I'll hold down the Option key or the Alt key on Windows to subtract. [00:02:02.0] These different edit modes are available also by clicking these icons - add, subtract and intersect. [00:02:13.0] The lasso tool does give me a different kind of option to chose anti-aliased or non anti-aliased. [00:02:22.0] And I will show you the difference between the two. [00:02:26.0] Choose Select menu>Deselect, and with my anti-alias currently enabled, [00:02:33.0] what it does is it softens the edge of my selection a little bit. [00:02:37.0] I will go ahead and fill that, and now I will disable anti-alias and create a new selection. [00:02:51.0] I will move that next to this one, and I will fill this selection. [00:02:58.0] And I will choose to deselect. [00:03:07.0] I will zoom in around the edge of these two by drag zooming, [00:03:12.0] so you can see. And notice how the anti-aliased selection has a bit of a dithered effect, [00:03:19.0] softening the edge. Whereas the non anti-aliased is a very hard-edged stair-stepping effect, and it's attending to the edge of the pixels. [00:03:30.0] So it's either yes or no, well an anti-aliased selection creates a, some intermediary colored pixels. [00:03:37.0] Usually you want to leave anti-aliased enabled. [00:03:46.0] All the selections allow you to edit some of the features using the Select menu, [00:03:53.0] which you seen me come up and chose from time-to-time. [00:03:56.0] I can choose to select everything by going to Select All. And you can see now my selection indicator, [00:04:05.0] this marching ants or dancing ants or moving line, however you want to call it, is around my entire image. [00:04:14.0] I can also turn off any selection that's activated by choosing Deselect, and that will deselect any currently active selection. [00:04:25.0] Reselect will reselect the last active selection. And to demonstrate how Inverse works, [00:04:38.0] I will first create a small selection. [00:04:41.0] This is currently selected, but if I choose to inverse the selection, what it does is, [00:04:54.0] it says select everything that was not selected and deselect that which was selected. [00:05:00.0] So now this area is not selected, and everything outside of it is selected. [00:05:05.0] So those are some other options that we have, and I will discuss more options of the Select menu later on. [00:05:11.0] [00:05:12.0]
