Making Selections in Adobe Photoshop 2020
we're gonna head into selection essentials. Selections will allow you to isolate part of your picture, so whatever it is you're doing will not affect the whole image. And so they're kind of essential to really be ineffective in federal shop. There's a variety of tools that could be used for creating them. There's a lot of new additions in the newer versions of federal Shop, so let's jump in and take a look at what is possible. Now this image already has a selection within it, just so I can show you what it looks like in case you're new to photo shop. If I look at this image, you'll see that a particular area has its edge highlighted, and that's known as a selection. If you would actually look close at it, you'd see that this edge is actually kind of moving along clockwise, and it almost looks like a little bitty ants walking around. And therefore a lot of people refer to that as the marching ants. But any time you hear somebody say that they mean that edge, which indicates there is an ...
area selected, I'll show you the tool used to create them. But before we do, Let's look at why do I need a selection? What's it going to do for me? Well, whenever you have a selection active, then if you go to the image menu and you choose any one of these adjustments, let's say in this case, I chose the one called black and white. Well, usually it would affect your entire picture unless you had a selection with that selection active. When I choose black and white, it's only the area that was selected that is affected, and therefore, whatever I do here is only going to effect the selected area. A click cancel that is also true. If I were to go the filter menu in, apply a filter. In this case, I'm gonna use Blurring Ghazi and blur. It's the adjustable blur filter, and if I bring up the setting high enough so it becomes obvious, you'll see that it's on Lee blurring the area that was selected. Also, if you were to grab a painting tool and decide you wanted to paint across your image well, that paint would not apply outside of that selection, and it's only when you extend into the area that selected that you would see the change happening, and so selections are essential any time we want to work on. Only a small portion of the picture in selections also are related to other features and Futter Shop. If you ever heard here of somebody saying they need to mask something, they really mean they need to select something. Selections in masks go together. A mask is just when you would see this selection is something other than marching ants. Instead, you would see it as a black and white image where the area that is white would be selected in the area that is black would indicate what's not selected. If you want to see an example of that, I'll take the selection that's on my screen right now. I'll go to the select menu, and there's a choice here called Save Selection, and I'm saving this when I dio I can't type. So, uh, it puts it somewhere in the place that happens to put it is in a panel called the Channels panel. But here it is. Do you see that shape Well, Any time you see something, it looks like this where an area that's white indicates where something was selected in an area that's black indicates something that's not that could be described as a mask. It's just to say I isolated in an area somehow in photo shop, and it doesn't look like the marching ants. Instead, it looks like a black and white representation that's usually the same size as the document you're working on, and that's a mask. But the two are synonymous where you can have a mask attached to something like an adjustment. And then it's the equivalent to having a selection attached to something. So it limits where ever that thing can affect the image. But master the subject of a different class, I'll have a class on advanced masking that really means advanced selections. All right, let's take a look at the tools we use for making selections. I'm gonna get rid of this selection, and I can do that by going to the select menu. In choosing de select when you don't have a selection active on your screen, it's the same thing is having everything selected when you don't have a selection. It means I didn't try to isolate an area, and therefore I'm gonna affect everything that means any adjustments that I make, like that one I used called black and white will affect the entire picture. And if I were to do a filter like the blurring that I attempted earlier again, it's going to affect everything. And you could just as easily have gone to the select menu. There's a trois called all and that would make it so. Your entire image is selected and you'd see the marching ants all the way out on the edge of the picture where if I zoom out so you can see the entire picture, you see the marching ants out there so select all and nothing selected or, in general, the same concept. It means I'm working on everything. Uh, I'm gonna choose de select to get rid of that. There is an occasion when you do need to choose, select all one of those is if I go to the edit menu until I don't want to copy something. Well, when you don't have a selection, it means it doesn't know how much of the image you'd like to copy which portion of the image. And so if you wanted to copy the entire thing, you'd have to select all first, then it would let you copy. So but in general, select all and de select means work on the whole thing. I'm gonna use de select a lot. And whenever I do, I use the keyboard shortcut, its command D on a Mac, control D and windows for de Select. And I'll use that without thinking. Like right now. I wanted to get rid of the selection, and I almost typed it without mentioning.
