Join Julieanne Kost for an in-depth discussion in this video Tilt shift, iris, and field blur effects, part of Photoshop CC 2018 Essential Training: Design.
- [Instructor] Photoshop has a number of different ways to add creative blurs or selective focus to your image. Before adding the filter, on the background layer, I'll right click and then choose covert to smart object. This will allow me to apply the filter as a smart filter. Under the filter menu, I'll choose blur gallery and let's start with Iris blur. The pin in the center of the iris blur, allows me to reposition the blur within the image area. I can also change the amount of blur, using the dial on screen, or under blur tools I can use the slider in order to increase or decrease the blur.
In order to resize the blur, I can click anywhere along the lines to shrink or enlarge the area that's blurred. To make the oval or the ellipse look more like a rectangle, I can click on the square icon and drag out or drag in. If I want to rotate the blurred area, I'll position my cursor next to one of the small white dots. When I see the double headed arrows, I can go ahead and rotate. I can also change the shape and the size of the blur by clicking on the white dot.
Everything between the larger white dots and the pin in the middle, has no blur applied. The blur starts at the white dot and becomes completely blurred by the time it hits the white line. I can change these white dots position by clicking and dragging. So now we have less of a center area that's blurred, and a longer blur fade. If I want to move one independently of another, I can hold down the option key and click and drag. Holding down the option key, I can also drag it closer.
Now let's take a look at the tilt shift affect. I'll uncheck the iris blur, check the tilt shift, and then click on tilt shift in order to see the settings. Again we have a pin in the middle of the interface which I can use to reposition the tilt shift. I can also use the dial to increase or decrease the amount of blur. The area between the two white lines has no blur applied at all. The area between the white line and the dotted line, that's the fade range.
So it starts to blur and by the time we get to the dotted lines, it'll be completely blurred. We can click on any of these lines in order to reposition them. If I hold down the option key and click and drag, both lines are affected. If I want to rotate the tilt shift, I can position my cursor close to the white dot. When I see the double headed arrows, I can click and drag. If I want to add distortion in the blurred area, I can click to drag the distortion slider.
To the right to add distortion it goes in one direction, and to the left in order to have it go in the other direction. If I want symmetric distortion, I'll click the check mark. Alright let's take a look at the third blur. This is the field blur. I'll uncheck tilt shift and then enable field blur by clicking on it, and then click on the name of it. Now at first you might think that the field blur doesn't do very much. You have a single pin and you have the blur wheel. However the way that the field blur is meant to be used, is with multiple pins.
So I'll click in this front pear, and then I'll change the blur amount to zero. I'll add another pin in the second pear, and just decrease the blur amount a little. And in this last pear, I'll make sure to increase the blur a bit. So now I'm imitating a depth of field effect in post processing. If I want to add another blur, I can do so right over here, just to blur this area a bit. If I hold down the M key, we can see the mask that photoshop is creating.
Where the mask is white, we'll be able to see the blur and where the mask is gray or black, it's hiding the blur. But in this case, it's really the amount of blur or the intensity of the blur. So it's not really just making it more or less opaque, but it's actually adding more or less blur. Alright I'll release the M key. If you tap the P key, we get a preview of before and then tap the P key again, and it'll show us after. Hold down the H key if you want to hide the interface.
Release the key in order to display it again. When you add a blur to an image, you might want to apply a little bit of noise so that the blurred area doesn't look so smooth. I'll zoom in to 100% by using command one, hold down the space bar, and then, pan across to this first pear. In order to add some grain to the image, I'll use the noise panel. I'll increase the amount which is the amount of grain. I can change the size of the grain, making it larger or smaller.
And I can change the roughness. If I move this to the left, it almost looks like the image has been reticulated. If I move it to the right, it gets much rougher and clumpier. As soon as I achieve the affect I'm after, I'll click okay. In order to apply that blur non-destructively, I'll zoom out using command zero and we can look on the layers panel I have my smart filter, and underneath that, blur gallery. If I want to make changes to this blur, I can double click on blur gallery. If I want to hide the blur from anywhere, like for example the top of this pear, I'll click on the mask for the smart filter, tap the B key to select my brush tool, make sure that I'm painting with black, at a 100%, and I'll paint over the area that I want to hide the blur and reveal the original image.
So you can see between the iris blur tilt shift and field blur, there are a number of ways to selectively blur your image in Photoshop.
Photoshop CC boasts tools and features for making tonal and color adjustments, applying effects and treatments to type and graphics, and distorting, filtering, and layering elements—all while maintaining the highest-quality output. In this course, Julieanne demonstrates how to efficiently perform common design tasks, including editing images, drawing shapes, and working with type and fonts. Along the way, she shares the secrets of nondestructive editing using Smart Objects, and helps you master features such as layers, filters, blending modes, typography, custom brushes, vector masks, and much more—increasing your productivity every step of the way.
