In this movie, I'll show you how to apply the final blur gallery filter, which is Tilt Blur. Like Iris Blur, Tilt Blur allows you to create gradual-focus transitions. However, they are linear transitions as opposed to radial. And among other things, you can create fake miniature effects. So in our case, we are going to take this bustling street scene and we are going to turn it into this thriving little tiny town. So, switch back to my image at hand. And notice that I have converted the image to a Smart Object and then I applied trio of Smart Filters.
I'll go ahead and turn the Smart Filters on, so you can see. First I applied a big helping of Reduced Noise, and I'll just go ahead and double click on Reduce Noise so we can see the values. I set the Strength to 10, both Preserve Details and Reduce Color Noise is set to zero, and then I actually cranked up Sharpen Details to 75% because, as opposed to trying to correct the image, I'm trying to achieve an effect. Then click OK. And the idea here is we are trying to turn these people into little toys, essentially, that are made out of plastic. Then I applied Median with a radius of two pixels and finally, I added a dollop of Smart Sharpen, at 200%, with a radius of one pixel, and Remove set to Gaussian Blur. All right! Let's take that layer and make a copy of it by pressing Ctrl+A or Command+A on the Mac, and then press Ctrl+Alt+J or Command+Option+J on the Mac and call this layer Tilt Blur, and then press Enter or Return.
Next, go up to the Filter menu, choose Blur, and then choose Tilt-Shift. And you can see that we now have this linear transition. So the idea here is the pin represents the point of focus. And I'll go ahead and move that point of focus onto the front of the bus. And then these first lines represent the area that will remain in focus, and then the dotted lines represent the area that's out of focus. And of course beyond the dotted outline, we have the lower focus, which by default is a blur radius of 15 pixels. The area between the solid line and the dotted line gradually declines in focus.
Now if you want to change the angle of your Tilt-Shift, you could just go ahead and drag on that white circle like so, and you will see the angle in that little heads up display, and you can also drag the circle in order to move that line of focus there. But if you want a little more control, because you can see that you end up making pretty big changes very quickly when you drag on the circle, another way to work--I'll go ahead and press Ctrl+Z or Command+Z on the Mac to undo that change--is to click and drag. So as opposed to just clicking, which will set another pin--we don't want that, so I'll press the Backspace key or the Delete key on the Mac, and then once again click on the pin inside the bus-- you can drag farther away from the center point like so, and that's going to give you a lot more control over the rotation.
Now, in my case, I don't want any rotation, so I'll press Ctrl+Z or Command+Z on the Mac. And I'm going to drag this circle down, like so, and I'm pressing the Shift key in order to constrain the angle of my drag to exactly vertical. And I am going to drag it to the top of the face of the bus there. And then I'm going to drag the one below while pressing the Shift key to the bottom of the face of that bus, so just the bus face is entirely in focus. And then I am going to drag this top line up. You don't need to press the Shift key this time around because we are not changing the angle.
And I'm looking for the dotted line to intersect the windshield of that cab right there. And then I'll scroll down. And even though that lower dotted outline appears outside the canvas, you can still drag it to a new location. All right! I'll just go ahead and reset my view by pressing Ctrl+0, Command+0 on the Mac. In addition to the Blur value, you have this Distortion value, and we are going to get a better sense of how Distortion works if we increase the Blur. So I'll take it not quite that high, maybe to something like 30 for now. And now I'll turn on Symmetrical Distortion, because otherwise you are just going to get a distortion in the foreground.
If you turn on Symmetrical Distortion, you will get a distortion in the foreground and the background. And now I'll go ahead and reduce the Distortion value, and you can see that the blur is distorting from up-left to down-right; and then if I increase the Distortion value, it goes in the opposite diagonal direction. In my case, I want a distortion of about 20%. And I'll then Shift+Tab to the Blur value and take it back down to 15 pixels. All right! So assuming that I like my effect, I'll go ahead and click OK in order to accept my changes, and I ultimately achieve this version of my tiny town.
So that's how you use the Tilt-Shift filter inside Photoshop, but let's imagine that you want to create some more points of focus inside this image. Well, you can combine the various blurs with each other, and I'll show you how to do exactly that in the next movie.
