We are going to go ahead now and take a look at how you control the Image Hose, and in order to show you this, I'm going to be using various sample Nozzles that are built into Painter. So anything I show you here is something you have access to through the Nozzle Selector. I am going to select Urban Fixtures, and I'm just going to draw with it a little bit here, and now I can control this and I'm doing this by bearing. So depending on the bearing of my pen, I can literally control the angle this is coming out with.
So a couple of things come to mind. A) How do I know that? And B) how do I know what other Image Hose Nozzles are going to do? I'm going to go ahead and open up the Variant Category list now, and let's take a look at this list. There are basically two categories of Image Hoses. You'll see there is one whole set here called Linear Image Hoses, and there is a second set that are Spray Image Hoses. Let me start off by just describing the difference in those. So let's undo this.
I'm going to select another Nozzle element in this case. I'm just going to select the Bay Leaves we used earlier. Now you'll notice this is Linear, so when I draw with this, it just comes out in a linear fashion. That's why we call linear. If I go and select a Spray, what's going to happen is you see now they're coming out widely dispersed. So a Spray is more random in that it just sprays them out. So that you have not less control, but you have more randomness built into the dispersion, where as a Linear version of this just does a nice perfect line.
There is a reason for that. I mean you can already I think see this. As I draw this, I can already kind of draw a wreath or something, using it this way, whereas when it's the Spray version, well, you're going to get something altogether different. But each has its purpose and that's why the two kinds of Nozzle elements are in the list. So that's the first division. Then we get into these different kind of encoded things. There is a bit of a code here, and I'm here to crack the code for you. So the way this works is in the case of Linear-Angle-B what it's telling you is that angle is controlled by B, and what is B? B stands for Bearing.
I'm just going to go down the list here and describe these for you, so you understand what these letter designations mean and then it starts to get very understandable. Whatever proceeds that letter, that's what it's controlling. So W is for Wheel. Now that doesn't make much sense to probably 99% of the Wacom users, but the other 1% have the Airbrush pen which is actually shaped a bit like an airbrush and it's got a little wheel mechanism on it. So it mimics the mechanics of a traditional airbrush.
This is controlled by that wheel. P stands for Pressure. So as I press lightly or hard, you can see I'm going to get a change in the scale of the Nozzle element. Then we go on down to or we have multiple elements controlled. This one is size is controlled by pressure, but angle is controlled by my bearing, and the size is controlled by pressure. So I'm controlling two dimensions here. Now I've got the control over the bearing, which way the elements are pointing, but I've also got control over pressure, which controls the size of those elements.
So as I do both, I actually have interactive control over both characteristics of it. That's what nice about the Image Hose. It does borrow heavenly from the vocabulary of traditional hand and stylus based instruments. If you go down little further, then you've got size is controlled by pressure, and angle is controlled by direction. So what that means is with this when I draw the direction I'm going and it's kind of hard to explain how this works, but I can feel it. As I go a different direction, the angle of the elements are changing.
Then I have also got pressure controls and I'm drawing smaller and larger based on pressure. Some of these won't make sense to you totally until you actually try the tool out in conjunction with an element like this. This happens to be a very good demonstration element, because it's a linear object. You're very sensitive to how your hand is changing. In this case, you'll be able to go, oh yeah, I'm controlling angle in this case by bearing. Now I want to show you the angle and direction. This is the one that I have started off. Now this one is based on my direction. So all I have to do is draw in a direction and it's pointing in that direction, and then I have also got control with the size.
Now it might make a sense to go with a set of signage polls like this. But because it's a linear element like that, it makes sense to use it as a way that shows this off. In fact, you can see as I start drawing with it, it starts losing its objectness. Now it's starting not even look like a set of street signs and it starting to just be this kind of interesting mark. So that's the other thing. I mean there is a little limit to what you can do with visual elements. So we have size is pressure and angle is random.
This can be very useful because what's going to happen here is now we are getting random angles, but we are controlling size and this is a great demo, so you can see who it's random, but this actually works much better with something like some sort of a natural element. So now each one of those leaves is turning to a random direction, pointing in a random angle, but I still have control over the pressure. So this is where you could start to draw something, and if you want to play with either perspective or just various sizes within something you're spraying out, you can do it with this because you are getting a random angle as each one of these is being lay down.
But you still are controlling the pressure or the size with the pressure of your hand. So that's another interesting combination. Then here is the wheel once again. Since if I don't have one, I'm not going to through it. Now you have linear sizes just random. So pressure makes no difference here. It's just spitting these out in a random order, but in a linear fashion. If we go down to, now we have size is random, but angle is controlled by direction. Now this might make more sense to use the light fixtures again here. So let's go down here and get this and now the size is random, but the angle is controlled by direction.
So you can see here with all of these settings, you've got a wide variety of possibilities in what you can do. Most of these are doubled when you get into the Spray. For example, for a Spray it's random size by pressure. But now here is where if I want to control this, what do you think the combination would be for getting these to rotate at any direction just on their own and yet I control the size? You would want an angle to be random and size to be pressure. So if we go down here and find where size is controlled by pressure, angle is random.
So now I have got something where I can paint with it, and it's all coming out in random fashion, and it's also a Spray. Now you can see how these are just being widely dispersed as I spray. And I'll show you one another control that's useful to know here. The reason these are spraying is they take advantage of the Jitter control. Jitter is what controls the linearity. So if I put this down, you'll see this is just a linear brush. So all the linear brushes just happened to have jitter. The control that sets how far afield from the actual stroke elements are laid down.
When it says zero, it's going to be linear. As I start to turn this up, it's going to get more and more scattered when I spray. So if I go all the way up to the maximum level of 4, I'm going to get the maximum dispersed brush. So I even have control over how random a Spray is or how tight it is based on this litter Jitter control that's always available to you when you are in the Image Hose. So really what you've got here is a really wide different variety of hoses that you can use to do just about any kind of action to the elements you want, whether you wanted to be in a very linear fashion, a very random spray fashion which you can control, and then various combinations of all of the different attributes about what happens with those elements as they're sprayed out onto the canvas.
So this gives you the basic control over the Image Hose. And the last thing I want to show you, because I don't want to forget this because this is also important, is you can then control the overall size of this. It's still based on your Size slider. So if I want larger versions of this, just turn the slider up and now I'm going to get very, very large elements. I'm still getting all the way down to the little, but you can see that you have complete control over the ultimate size of them by controlling it with your Size slider. So now here it's like we are getting hit over the head with San Francisco street signs.
Anyway that's your basic control of Image Hose Nozzle elements. In the next video, we are going to take a look at how you can make your own Image Hose.
