Join Nigel French for an in-depth discussion in this video Working with the Spin Blur filter, part of Photoshop for Designers: Filters.
- [Voiceover] The Spin Blur filter is a more sophisticated version of the old Radial Blur filter that's been around since the dawn of time. While the Spin Blur filter is easy to use, on a wheel, a windmill or anything spherical, most images will contain elements that would remain stationary and be unaffected by the blurring motion. Depending on the image, this might require simply painting out the element using a layer mask or filter mask. Or could require complex masking and exposure adjustments to achieve a plausible result.
Let's start out with a relatively easy example. I'll come to my Layers panel, and press Command+J to duplicate the background layer. On Layer 1, I'll convert it to a Smart Object by Right or Control clicking to the right of the layer name. I'll then come to the Filter, Blur Gallery, Spin Blur. I'll zoom out a couple of times and then reposition my blur controls. And then resize and reshape them. If I drag from one of the handles, I am distorting the shape.
And if I drag from the edges, I am scaling out proportionately. Now what I want to do here is I also want to offset the center point. And to do that, I hold down the optional Alt key as I drag away from it. And I'm gonna put that on what I estimate would be the center of the wheel. So after a bit of back and forth, I've now positioned and reshaped my Blur controls so that they cover all the elements I want to be affected. I'm going to take down the blur angle.
I could do this with the onboard controls right here just by pulling that around. I tend to find it easier using the slider. So I'm gonna take the slider down to 10 degrees. We also have some very interesting motion blur effects which I'm not going to look at in this movie. But we'll be covering it in a later movie. I'll click OK. And that looks fine. Except, I'll just turn that off for a moment, the moon itself would not be moving. So what I want to do now is just add a layer mask to Layer 1.
And then paint a hole through Layer 1 so that we reveal the stationary moon on the background layer. I'll tap the B key to go to my Brush tool. Let's zoom in on this. I'll turn off the Smart Filter for a moment. And then on that layer mask, I will be painting it black. And nothing's gonna appear to happen for a moment because we've got two identical layers on top of each other.
But when I feel like I've painted out that shape, accurately enough, let's turn off the Background layer and see what's going on there. Okay, so you can see I'm just knocking a hole through. I'll now turn back on the Smart Filter. And we can see that there are some problems with it. So I just need to fix that up. I'll go back to my white brush and and clear up any edges to remove them. And on last thing I might wanna do is go to my Layer Mask and reduce the Density of that layer mask.
I'm gonna go down to about 80%. I feel like I still need to get in a bit tighter on that. And there we have our finished result. The ferris wheel moving, the moon stationary.
