Starting to Work / Selections and Marquee Tool
Subtitles of the Movie
[00:00:00.0] When you use Photoshop, you are almost always going to want to isolate an area to do something with. [00:00:07.0] And this is integral to understanding how Photoshop works. [00:00:11.0] It's almost always a two-step process. [00:00:13.0] You select an area, and then you do something with the selection. And to demonstrate that, I will go over to my lasso tool and create a very crude selection. [00:00:28.0] So I have selected my lasso tool and I am clicking and dragging around my apple here. [00:00:33.0] Step 1 - I have a selection. And step 2 - I will do something to it such as invert the brightness value. [00:00:51.0] I will undo that. So just to reiterate, and this is a very important point I want to make, is that the way Photoshop works is always a 2-step process. [00:01:09.0] Select an area, and then do something to it. Select an area, copy and paste, and of course when I do that I actually paste into a new layer. [00:01:24.0] Well Photoshop gives you many different ways to select an area. And I should also mention that if you don't have anything selected, [00:01:38.0] then the default for Photoshop is selecting everything. So with this layer selected, if I choose to invert the brightness value, [00:01:54.0] it will do that on every pixel - because the default is to run the effect on everything if there is no area selected [00:02:11.0] or isolated for Photoshop to know that that's where you want to run the effect. [00:02:15.0] I am going to demonstrate how some of these selection tools work, and I will start by using the rectangular marquee tool. [00:02:28.0] Rectangular marquee tool allows you to create rectangular selections. So with my rectangular marquee tool selected, [00:02:36.0] I am going to click and drag diagonally over an area. And when you let go, you can see that that is the area that I have currently selected. [00:02:46.0] If you move the selection tool into your selection, you can see I get this icon. And what this means is, [00:02:56.0] this allows me to actually move my selection area without moving any data in it. [00:03:03.0] So this is not editing my picture, this is just repositioning where I want my selection to be. [00:03:09.0] I could add to my selection by holding down the shift key or by going up and choosing this icon right here. [00:03:18.0] And if you have tool tips enabled and you move over that icon, you can see that what that does is it adds to the selection. [00:03:26.0] So in the old Photoshop you had to know the key command, now you can just choose what option you want. [00:03:32.0] So now I can click and drag, and you can see my selection has been edited with this new additional area. [00:03:42.0] I can also add portions to the selection that are outside this. Conversely I can take away from this selection. [00:03:55.0] Also notice how my cursor has a small plus next to it when I am in the selection add mode. [00:04:03.0] I am going to choose to take away, and now my cursor has a small minus next to it. And you can see that I have just taken away from that selection. [00:04:18.0] This last option will give you the intersection of whatever you have deleted from. [00:04:35.0] So with the selection active, I am going to go over to the intersection option. And you can see what it's done - it's left the intersection of those two selections. [00:04:48.0] I'm going to choose Select menu>Deselect, or command or control + D to get rid of that selection. [00:05:04.0] Some other features and options available to us in the Selection Options palette are the ability to feather or soften the edge of a selection. [00:05:15.0] That's this value right here - and currently the value is setup to be pixels and I will leave it at 0 pixels, create a selection, and fill that selection. [00:05:26.0] So I will choose Edit menu>Fill, and I will choose it to fill with my foreground color which is this pink color. [00:05:32.0] And you can see it's created a very sharp edged selection. Now if I edit this value, and I will type in 10 pixels now, [00:05:46.0] so now it's going to create a 10 pixel feather for my fill. [00:05:50.0] I will come over here and I'll drag out a selection diagonally, and since it's a square selection, my feathering has actually softened the edges a bit, [00:06:01.0] and I will fill that again to show you the difference. Edit>Fill - foreground color, select none. [00:06:11.0] So you can see, it's created a much softer edge. [00:06:14.0] I will go ahead and bring that back to 0, and show you some other options that we have with the selection tool. [00:06:24.0] If you hold down the Option key on a Macintosh or the Alt key on Windows, you can drag a selection from the center. [00:06:33.0] And that's different from normally, it drags from edge to edge, and I always select and drag diagonally. [00:06:45.0] So again that's holding the Option key down before you begin to drag a selection. [00:06:52.0] With my style selected as normal, notice I can resize and reshape my selection on the fly. [00:07:04.0] However, if I hold down the Shift key while I drag diagonally, it will constrain my selection to a perfect shape. [00:07:19.0] And in the case of my rectangular selection tool, it will constrain it to a square. [00:07:24.0] I can perform that same function by choosing to constrain the aspect ratio. And if you type in 1 for width and 1 for height, [00:07:38.0] you will get the same effect, the square. And you can go ahead and change those numbers if you wish. [00:07:43.0] I will change it to 3 for the width and 1 for the height, and I will get a very long selection - and notice it's always constrained to a 3:1 ratio. [00:07:54.0] The last option I have under style is to choose a precisely fixed size. [00:08:01.0] Type in exactly how big you want it, say you wanted a 32 X 32 - that would be a 32 pixel and I will type in px for pixel, [00:08:16.0] so size selection. And now all you need to do is simply click, and you'll instantly have a 32 pixel square selection. [00:08:26.0] So that's called fixed size. So there are several different options that you have with the selection tool up here available to you in the Options palette. [00:08:34.0] And you will see how these work and other selection tools - they work essentially the same way. [00:08:40.0]
