Combining Selection Tools
we can combine selection tools. So in this case, what I'd really like is not only this round portion, but I either want to get rid of the door, or I want to add the door to it. And so I'm going to switch back to the normal marquee tool, and let's figure out how to add to or take away from a selection. When you're in a selection tool in the options bar at the top of your screen on the left side, there should be some icons right here. Those icons determine what happens if you click with this tool. A second time in the default is the one on the far left. If I hover over it and pause, it will give me a tool tip indicating what it means. It means make a brand new selection. That means replace the selection that already exists. Therefore, if I move my mouse near the upper left of my picture, I click and I drag the selection I had previously goes away as it makes this new one, I'll choose undo the second icon that is there. If I hover over it, it means add to the selection that's already exis...
ting. So if I click that icon before I click and drag within my picture, then when I make a new selection, it simply adds to the one that's already there. I'll choose Undo because I wasn't careful with where I clicked and I'll go to the lower left of the doorway. I'll click and I'll drag up like this to try to include that lower portion. So now we've combined to selections. If I go back up here and I go to the third icon, the 3rd 1 is called Subtract from Selection, and if I click on that now, I can take away from this. So if I don't want the blue portion, which is the doorway itself, then I'm gonna start near the bottom of my selection just outside of the area that selected already. Ah, click and I'll drag up like this. You get all the way up to where the blue edge of the door is, and now, because it's set to subtract from the selection, now have an area selected that is three round portion that is brown along with the frame that is around the doorway. So that means on the right and left edges. So maybe I want to come in here now in a just that all again go to hue and saturation because that has a huge slider which allows me to shift the colors of things. And we'll do that. So we've changed up the color. Now what I'd like to do is the area that is above the door. There is a area that has a curve top at a flat bottom that's directly above the door. I would like to select and work on that separately. So up here in the upper left of my screen, there is the last of those four icons. And if I hover over it, it's called Intersect. With selection, you could think of that as meaning. Let's crop the selection we already have. So we only keep the portions that are contained within the next selection I'm making. So I'll come in here knowing that I'm going to crop the selection So Onley where it overlaps the selection I'm currently making. I'm gonna click on the left edge of the door and I'm going to drag up like this and let go, and it gives me on Lee the area where those two selections overlapped, and it's extending down further than I need. So I'll start a selection up here, come down like this and just that much the head crop within their now I just have that top portion. So if I want to make that a different color again, I can go here to hue and saturation and let's see if we can end up getting that to be maybe a more of a reddish and maybe bring up our lightness a little. But you've seen how I've been able to isolate various portions in this image and now choose de select cause I want to work on the entire picture now. I showed you that using the icons that were found in the options bar at the top of my screen. But to be honest, I never click on those icons. Instead, I haven't set to the default setting, which is on the far left, which is the one that would get rid of a selection and create a brand new one. And that's because I can do every thing we did with those icons using my keyboard. If you're gonna end up using photo shop on a daily basis would be useful to get used to the keyboard shortcuts. Forward those. So let's take a look. First, I'm gonna make a selection of the rectangular portion of the doorway, so I'll click in the lower left of the door, drag up like this since I know I'm going to select the whole circle. It doesn't matter how high I go, as long as I go above right about here where the circle would start intersecting with it. Now I want to select the round portion of the door and I'm not sure why it's doing this. We have this wierd. It shouldn't be showing this part of the selection because the actual edge extends down here. That's an odd little screen redraw issue that shouldn't be happening to see where anyway. Now I want to add to it, so I'm going to switch to the elliptical marquee tool before I click the mouse button. I need to hold down a key on my keyboard. And if you watch these little icons up here when I hold down the shift key Oh, I thought that was gonna push in, but it didn't. It's does the equivalent to that. So I'm gonna press and hold down the shift key. If you actually look at my mouse, it usually looks like this When I hold shift, you see a plus sign indicating I'm gonna add to my selection. So I'm holding shift. I'm gonna guesstimate where With the upper left corner of a rectangle B that contains that circle I click and after I click as long as my mouse button is held down I can let go of my keyboard because it's on Lee. The absolute moment that I clicked that it matters If I was holding shift or not. After that you can let go so I can hit space bar here in reposition this Let go Space bar there. I've added to my selection to take away from my selection. What? I end up doing this. If you look at my mouse here, If I hold down the option key, which is Alton Windows, you'll find a negative sign appears in. Therefore I can come into her hold option and I'm gonna take away the blue portion of the door. Can't do it with that tool. I can choose. Undo Forgot to switch to the rectangular one, but I'm holding option Alta windows so I could get that. Now I want to get the intersection. I want to crop the current selection so I only get it within the area that I draw to do that. If you watch my mouse again, I'm gonna hold on both shift and option at the same time and I get a little X. That X indicates it's gonna give me the intersection. I'm gonna click like this, drag down, and if it's not positioned exactly the way you need space bar lets me move it. But it's on Lee the moment I click my mouse button when I have to be holding down those two keys after you click the mouse. As long as you have the mouse down, you don't have to continue holding them in there. I could get our section, so I get used to those keyboard shortcuts. Therefore, I don't have to use the I consider found up here at the top of my screen unless I really want to. If use Futter shop just every once in a while, you use the icons, and if you use Photoshopped daily, get used to the keyboard shortcuts
