In this movie I'll show you a positive use for noise in which we create a kind of texture in order to achieve the effect of the image having been painted onto a coarse paper background. So we'll start where we left off in the last movie and we're going to click on the high pass layer to make it active and then I'm going to create a New layer by pressing Ctrl+Shift+N or Cmd+Shift+N on a Mac and we'll go ahead and call this layer texture and then click OK. Next I want you to convert this layer to a Smart Object by going up to the Filter menu and choosing Convert To Smart Object or if you loaded dekeKeys press Ctrl+, or Cmd+, on the Mac. Now we're going to heap on a bunch of filtering effects, but first you want to press the D key to establish the default colors of black and white for the foreground and background respectively.
Then go up to the Filter menu choose Render and choose Clouds, and Clouds applies what's known as Fractal Noise, meaning that it's a random noise pattern and you can change it any time you like just by double-clicking on the word Clouds there in the Layers panel. And notice every time, you double-click you get a different effect. We don't need that Filter Mask, it's just junking up the panel, so right-click on it and choose Delete Filter Mask. Now let's add some Noise to our clouds by going up to the Filter menu, choosing Noise and choosing Add Noise, which I've given a keyboard shortcut of Shift+F7. Now if we'd added some painterly effects to a photograph and then we wanted to turn around and match the Noise Level in the photo, so everything looked organic, you would keep the Amount value low, something in the range of 2 to 4%.
However, we want a big effect here, so I'm going to increase the Amount value to 20%, set Distribution to Gaussian so that we have a higher contrast noise effect and then turn on the Monochromatic checkbox to get rid of any color noise. Then click OK in order to apply that effect. Next we want to increase the size of our noise a little bit, because right now we just have all this single pixel noise as you can see now that I've zoomed into the image. To achieve larger noise you go up to the Filter menu, you choose Blur, and you choose Gaussian Blur, which I have given a shortcut of Shift+F6, and then I'll set the Blur value to 2 pixels, like so, and click OK. And then finally we want to turn this effect into a texture and you do that by going to the Filter menu once again, this time you choose Stylize and now you choose Emboss. And these are the values I want you to apply; an angle of 135 degrees, a height of 2 pixels, and an amount of 500%, now click OK in order to create that texture.
And then finally you blend it with the composition by changing the Blend mode in the upper left-hand corner of the Layers panel from Normal to Soft Light, and we'll end up achieving this effect here. I am going to press Ctrl+0 or Cmd+0 on the Mac to zoom back out. Now that creates the effect of the Paper Texture but we still have yet to create this painterly effect right here and we achieve this using yet another merge version of the composition combined with a couple of filters and a Blend mode. So I'm going to switch back over to a composition in progress, I am going to turn off the texture layer. Click on the high pass layer to make it active and then press Ctrl+Shift+Alt+E or Cmd+Shift+Opt+E submerge all the visible layers onto a new layer. I'll call this layer bleed because the colors are bleeding into the paper.
Because we want to work with editable filters, go up to the Layers panel flyout menu and again choose Convert to Smart Object. And then go up to the Filter menu, choose Noise and choose Median, and I'm going to increase my Radius value to 8 pixels to really gum up that detail as you see here. So if were to click in the butterfly's face, this is what it look like in the first place, this is what it looks like now, all gooed together by this high amount of averaging. Now I'll click OK. And that gives us some pretty sharp edges. We want to diffuse them by going to the Filter menu, choosing Blur, and this time choosing Gaussian Blur and I am going to match that Radius value by setting it to 8 pixels and then click OK.
All right, we don't need the Filter Mask like usual, so this I'll take advantage of that dekeKeys keyboard shortcut of Ctrl+Alt+Q or Cmd+Opt+Q on the Mac, and I'll change the Blend mode this time from Normal to Darken. So we're just keeping the information on this layer that's darker than the stuff below it. And now I'll turn a Texture back on and then finally I'm going to brighten up this composition by clicking on the texture layer and then I'll drop down to the black/white icon at the bottom of the panel. Press the Alt key or the Option key on the Mac and click on it, choose Brightness/Contrast and I'll call this layer something like elevate and then I'll then click OK.
I'll press Shift+Enter or Shift+Return on the Mac to highlight the Brightness value and I'll take it up to 20 and then I'll tab to the Contrast value and take it up to 30 in order to create the final effect. And by the way if you're not happy with the texture all you have to do is double-click in the Clouds Filter associated with the texture layer. Photoshop may bring up an alert message telling you that you're only going to see the effects of this one filter. It's actually not true and I'm kind of sick of seeing this alert, so I'll turn on Don't show again and click OK, and you'll see the texture regenerate and just so we have a little more seamless transition time, I'll double-click in Clouds again and notice the scene changes in the background.
All right, I'll press the F key a couple of times in order to switch to the Full Screen mode, and I'll go ahead and zoom in on my artwork, and this is the final version of the artwork, including two different kinds of noise, Clouds and the Add Noise Filter used to achieve a vibrant and compelling effect.
