In this lesson video we are going to discuss about selection. selection is very important as we can use it for many different purposes. But essentially we use selection to constrain editing to only certain parts of our image. Now when I say editing, I mean it can be painting, it can be transformation, or adding image, filter, etc. We will cover more about these techniques later in Sharla. For now, let's see how we can create basic selection and how to manipulate it with shortcuts.

In Krita, all of the selection tools are grouped in here. Mostly, they have these dashed lines characteristic on their icons. The first selection tool is rectangular selection tool. To access it, we can click on it, then click drag anywhere on the canvas to draw the selection. Okay, before moving forward Want you to see the effect of selection to our working environment. If we select the Brush tool, and then draw some random strokes like this, notice we cannot paint outside the selection area.

Okay, now if we select the rectangular selection tool again and click drag again on the canvas, as we can see, the old selection region will be gone and we have a new selection as the replacement. If we select the Brush tool again, let's say we use this blue color now, if we draw some strokes again, it will be constrained to this new selection area. Okay, now when creating selection, we can use the modifier keys such as shift or control or the Alt key to have more control on the selection shape. For example, sometime we want to create a perfect square selection. We can create the square selection using the shift modifier key to do that, when you click and drag to create a selection, do not release the mouse or your pen. Yep, well in this condition, press and hold the shift key.

Notice the selection become a perfect square, meaning the width and height of it have the same length. Okay, so what about the control and the alt modifier key, the control key will make the size changing happen on all direction. I'll show you what I mean. If we click direct like this, without releasing the mouse, hold the control key. Notice now when we move our mouse, the reference for the size changes, it's not at the corner anymore. Instead, it will use the center of it.

Okay, now we can combine shift and control key together as needed. The last key modifier is out. We can use the Alt key to move the selection to a different location for Example. If I click drag like this without releasing the mouse, then press and hold the Alt key, we can move the selection to another location. If we release the Alt key, we can still continue the selection creation process. I know this might be troublesome at first, but with a little practice, you should get the hang of it, inshallah.

Okay, next is the elliptical selection tool. Well, essentially, this tool will create a circle or selection. And just like the rectangular selection tool, we can also use the modifier keys to control the selection creation process, we can use shift to make a perfect circle selection. We can use control to change the center of selection scale, and we can use Alt key to move around the selection after we have a selection sometime, we need to To go back to normal mode, where we can access everything again. Basically, we need to clear the selection. To clear the selection, we can use a keyboard shortcut Ctrl Shift a.

If you forget the shortcut, you can always go to the Select menu up here, and you can see the the Select command up here, the shortcut is Ctrl Shift a. Also from this menu, we can see we have additional shortcuts to control selection, control A to select the whole canvas and we have Control Shift I to invert the selection. Basically, invert selection will make the selected region become unselected and vice versa make the unselected region become selected. Let's see this command in action. Let's pick the elliptical selection tool and then click drag like this on the canvas while we have selection like this If we draw something with the brush tool, we can only draw inside the circle right now hold shift and Ctrl and then press I letter key. The selection is now inverted, we can see the merging ends on the border of the canvas now.

So this whole canvas is now selected except this inner area of this circle. So when we try to draw something with the brush tool, we can go everywhere except inside the circle. If you want to invert it back, simply press Shift Ctrl I again, okay, I'm sure you get the idea here. The last two tools we're going to cover in this lesson is the polygonal tool and the outline selection tool. The polygonal tool, which is this tool in here will create a polygonal selection by clicking and releasing the mouse. To finish up the selection.

You can either click again on The starting point or you can double click. And now we have a selection like this polygonal selection is suitable to select geometrical shapes that mostly consist of long line shapes, like architecture or mechanical objects or rough stones, etc. Okay, finally, the outline selection tool. Now this outline selection tool is a bit different from the polygonal selection tool, because instead of doing a series of click and release action, we use click and drag method. So after we select the tool, click then drag to draw the selection. When we release the mouse button, the selection creation process is finished and we have our selection as the result.

Mostly, the outline selection tool is good for selecting organic forms that has many spikes and random curves such as three leaves, whoosh furry animals or humans hair, etc. In other graphic software, this outline selection tool is also known as lasso selection tool. There is one technique of selection that you will see me doing a lot in this course, which involves combining the power of polygonal and the outline tools together in one go. To do this, first you need to be in the outline tool mode, then you need to hold the control modifier key. If you do this, we can click drag to create outline type selection, and we can do click and release to create polygonal selection. So for example, we can create a cotton candy or a simple three shape selection easily in one go with this method.

Just do so for click release like this. Then click drag to draw the leaves in this area Because it is more convenient to use this technique. I honestly almost never used the polygonal selection tool again, unless the selection that I need to make are only consist of straight lines.
