In this movie, I'll show you how to create this synthetic star field background. And well, it's not technically a transformation. It will transform the scene from what we have now and it's pretty fun. So, I'm going to Shift+Tab to bring back my panels here. And I'm going to turn off that Colors layer. And I'm going to click on the Top Glass layer. And drop-down to the black white icon right there. And I'm going to chose the Invert command. And then I'll go ahead and create an Invert Adjustment layer. Notice it doesn't have any options in the Properties panel, which begs the question, then why are you showing me this? But in any case, now we have white glasses against the black background.
Because the Invert Adjustment layer is reversing the luminance of everything below it. All right. Now I'll click on the Colors layer to make it active and I'll press Ctrl+Shift+N or Cmd+Shift+N on a Mac to bring up the New Layer dialog box. Call the layer Noise and click OK. Then, go ahead and dial in a B value of 15% for your foreground color. I've already done this in advance, but we want a color that's almost but not quite black. Then press Alt+ backspace or Option+Delete on a Mac. To fill this layer with that very dark gray. Now it create synthetic stars using a couple of filters and I want to apply them as dynamic smart filters.
So I'll right-click on this image and choose Convert to Smart Object. Then go on to the Filter menu, choose Noise and choose Add Noise. And the settings we're looking for are in Amount value of 20%, Distribution set to Gaussian. Monochromatic should definitely be turned on otherwise, you're going to get very colorful noise. And by the way, in case you're interested in the function of the distribution option. Uniform evenly distributes the luminance of the noise. Where Gaussian pushes the noise outward. So you have more dark and light noise. Meaning, you have a higher degree of contrast. Then click OK to add that Smart Filter.
Now, we're going to have a lot of layers. So I'm going to right-click inside this Empty Filter Mask and I'm going to choose Delete Filter Mask to get rid of it. Next, you want to go up to the Filter menu, choose Blur and choose Gaussian Blur. And you want to set the Radius value to two pixels. Now, I know that doesn't look like anything like you'd want in a million years. But as soon as you click OK, you're actually done with the first phase of the effect. We're done working on this layer, anyway. Now, we need to increase the contrast using a Levels Adjustment layer. So press the Alt key or the Option key on a Mac. Click the Black White icon at the bottom of the Layers panel and choose the Levels command. And that'll go ahead and bring up the New Layer dialogue box. Let's call this layer, Star Maker and then turn on the check box, Use Previous Layer to Create Clipping Mask.
In that way, we'll affect this layer and this layer only. Now click OK in order to switch over to the Properties panel. And you may need to adjust these settings a little bit. But here's what I came up with and it seems to work pretty consistently. Click in the black point value and change it to 55 and then tab over to the white point value and change it to 65. That's not enough stars for you, you can reduce the white point value and reduce the black point value, as well. If you're seeing too many starts, then raise the black point value and then raise the white point value in kind. So anyway, you should see an effect that looks something like this.
Then close the Properties panel. If you take a very close look at the scene, I'm going to zoom in here. You'll see that a lot of the noise is kind of piled against the edges, so we're seeing all these noise scraps at the top and around the sides as well. And to solve that problem, we need to scale the smart object. So click on the Noise layer to make it active. Now press Shift+tab to hide those panels and press Ctrl+0 and then Ctrl+minus or Cmd+minus a couple of times in order to zoom out from the scene, so I have a little room to work. And I'll press Ctrl+T or Cmd+T on a Mac in order to enter the free transform mode.
Now, this message right here is telling you that when you're transforming a smart object, its Smart Filters will be turned off. And so, that's just something to bear in mind. In other words, we're going to totally lose the effect. So click OK and you're just going to see a layer of blackness now because that 15% gray has gone black, thanks to the Levels Adjustment layer. And what you want to do is click on a little link icon up here in the Control panel and increase the width value to something like 110 and press the Enter key a couple of times in order to accept that change. And as soon as you press the Enter key the second time, Photoshop scales the layer and reapplies the Smart Filters. So you may end up getting a slightly different effect. I'm going to go ahead and zoom back in. The final thing that we want to do is drop out these blacks, so we can see the martini glasses in the background. So I'll press Shift+tab in order to bring back my panels and I'll change the Blend mode from Normal to Screen and we end up getting this fanciful effect here.
All right. I'm also going to turn on these text layers right there. And so I'll just drag across that eyeball column like so, in order to turn them on. And so as promised, we've managed to entirely transform this scene. By adding a synthetic star field that we created using a combination of Smart Filters and a Levels Adjustment layer here inside Photoshop.
