Brush Flow and Opacity Settings
Now we should talk a little bit more about our brush because there's something I neglected to talk about. And that is a lot of people want to know the difference between opacity and flow. And so I'd like to show you the difference there. When I choose a brush and I start painting with it, it looks out both the A pass ity and the flow settings to determine how much you can see through my brush. And if they're both had 100%. When I click and drying like this in the very center of my brush, you will not be able to see through the middle at all. I'll choose undo. If I change the opacity setting, then you're gonna be able to see through my brush in. So if I bring that down, let's say I brought it down toe 20% or somewhere near there. Now, when I click and I drag, you can see that I'm only getting a hint of this color showing up, and then I can go back and forth and back and forth and notice if I go back and forth. I'm not getting multiple coats of paint. It's not like having a can of spray ...
paint where the more times you go across the Moor coach to get. But if I do, let go of the mouse button and I click again, which I just did, we get a second coat of paint and it doesn't matter how many times have pain across that. It's only two coats now. Let go again in Click and I get 1/3 coat of paint and I can let go click and get 1/4. But to build up the effect, I have to let go of the mouse button and click again. Many choose undo a few times to get back to what we had earlier. Now let's bring capacity all the way up to 100 instead bring flow down to around 20%. And let's try the same thing. I'm gonna click here and I'm gonna drag and then I'm not gonna let go of the mouse, and I'm gonna drag in Dragon and Greg across the same area multiple times. So flow means how much do I want in my first paint stroke across the area. But if I paint across it again, I'm going to get Maura and Mawr and Mawr, so you could think of adjusting flow. It's like using a can of spray paint where the more times you go across an area, the more coats you get, the difference being that if you go slower, you don't get mawr and faster getting less because you get that with a can of spray paint. But it's just counting the number of times you go across. Then you can use flow and opacity together. If you bring capacity down, let's say I have it at 50. In fact, if you use the number keys on your keyboard, you're going to be changing the opacity if you're in the paint brush. So if I take five, I get 50%. Type nine you get 90% were type two numbers very quickly. To get a precise value, like 32% you gotta type three to really fast. So if I set opacity to 50% and I set flow to, let's say, 20% how does that work? Well, in the end, it's going to be that opacity determines the maximum amount you can get without releasing your mouse button, so that means they'll never get more than 50%. Opacity flow means how much of that maximum? Um, I going to get on the first pass, so I'm gonna get 20% of 50. Then if I paint back and forth and back and forth and back and forth, it's gonna build up. But it's never going to get above whatever the opacity is set to. Unless I released the mouse button, and only then could it add more so flow and opacity can be nice. It's a matter of do you want it to build up a zoo pain across and across. If so, adjust flow, or do you want it to not build up? If you happen to overlap, your pain strokes and you have to release the mouse button in order, ADM. Or if that's what you're looking for, instead, be using capacity and some people will get fancy and use both. The number keys on your keyboard will change opacity when you're in the paint brush tool, and if you hold down the shift key when you use the numbers, it will change the flow. Typing zero brings it to
