Video: Working with Iris Blur

Here we are going to take a look at how we can work with Iris Blur. So let's go ahead and turn off the check box for Field Blur and then turn on the check box for Iris Blur. Let's open up the dialog, and what this will allow us to do is to create a different type of a blur. Well, what Iris Blur does for us is it gives us this interesting interactive icon here. You can go ahead and click on one of the edge points to drag it. Here you can see I am changing the shape of this. I can also rotate this by clicking and dragging one way or another.

Working with Iris Blur

Here we are going to take a look at how we can work with Iris Blur. So let's go ahead and turn off the check box for Field Blur and then turn on the check box for Iris Blur. Let's open up the dialog, and what this will allow us to do is to create a different type of a blur. Well, what Iris Blur does for us is it gives us this interesting interactive icon here. You can go ahead and click on one of the edge points to drag it. Here you can see I am changing the shape of this. I can also rotate this by clicking and dragging one way or another.

Click on the middle point to reposition. What about these outer dots here? What do those stand for? Well, those determine how far or how enclosed the blur area is. In other words, if I want to push it out, I can drag those to the edge. I can also click on the square icon to change the shape. Here you can see this is more of a rectangle, or I can make this more of an oval. We can control the blur amount the same way that we controlled it with Field Blur.

Again, you can click on the slider in order to increase this so that there is more blur, or you can decrease this so there's less blur. You can also click on the slider, here, that you'll find on the icon. Well, what about adding more Iris Blur? Can you do that same thing that we did with Field Blur? Well, sure. Again, just simply click to add a point and then you can use all those controls again. Well, let's say that you don't want a point either with Iris or a Field, what do you do next? Well, in order to remove a point, all that you need to do is just simply click on it then press the Delete key. That will then remove the blur that you've added.

If you want to reactivate one of the blur points, well, just click on it, and then you can modify the controls. Another way to take things back to the default settings, or to remove a blur, is to click on this icon here. And this is really helpful, because when it comes to blur and to focus, sometimes things will just get a little bit out of control. Perhaps you will need to reset the image altogether. We will click on this icon, and it will remove all of those blurs altogether. Then to re-add a blur point again just click, you can then modify these controls--as we've seen here. Modify the shape and the space and where this blur is located.

Okay. Well, here I am going to go ahead and reposition this and then decrease the blur amount just a little bit here, and make this perhaps a bit bigger. Just a subtle blur amount, so it's subtly blurring out some of the other elements of the picture. Again, all of these graphics here are helpful because they're interactive but they're also distracting. I can't focus on the image. Well, to do that, press that H key, it hides that temporarily, and then you can click on the Preview button to see your before and after. You can also press the P key that allows you to see the before and after as well.

Well, once you've dialed in the blur that you think might work in order to apply it, simply go ahead and click OK. Let's do that here with this blur so that we can compare this to the background layer. This will then render or apply that blur. And the great thing about that process that I want to highlight here is that while we're working with the blur, it was all live. We are making changes and seeing it instantaneously, and then to render it, we simply click OK. It takes a little bit of time to apply that. Well, here now we can see the before and after.

If we turn off the visibility. Here is our before, and then here is our after. Let me zoom in a little bit closer so that you can see some of those details. Again, before. And then now after. So as you can see, these Blur filters are indeed really powerful, and they can help you come up with some really interesting and creative results. Well, there's one more blur filter to look at and that's the Tilt-Shift blur. Let's go ahead and take a look at how we can work with that in the next movie.
