Photoshop CC One-on-One is back, and this installment teaches you how to build on your basic knowledge and achieve next-level effects with this premiere image-editing program. Industry pro Deke McClelland shows you how to seamlessly move and patch areas of a photo with the Content-Aware toolset; stretch the brightness of a scene with automatic and custom Levels adjustments; create intricate designs with text and shapes; and morph an image with layer effects and transformations. Deke also shares his techniques for sharpening details, whether addressing noise and highlight/shadow clipping or camera shake, and converting a full-color image to black and white. The final chapters show you how to best print and save images for the web, making sure all your hard work pays off in the final output.
In this movie, we'll take a look at the inner workings of Global Light. And I'll show you how to rasterize your layer effects, that is convert them to pixels so you can edit them with other tools. Global Light is that unifying force that insures that you have a consistent lighting angle inside of your image. And it applies to the three directional layer effects, which are Drop Shadow, Inner Shadow, Embevel and Emboss. And it's a function of two options, angle and altitude. Now there's only one layer effect that gives you access to both of those options, and that's bevel and emboss. So I'm going to go ahead and expand the Spider's layer, and double-click on bevel and emboss in order to open the layer style dialogue box. And you can see that Use Global Light is turned on so this effect is part of the Global Light System.
And so are the other directional effects inside of this image including by the way, the Inner Shadow and Drop Shadow effects that are assigned to this layer. Both of them have use Global Light turned on. Were I to make any modifications inside of this little circle? I would change the lighting throughout the image. Let's say I don't want to do that. Let's say what I want to do is change the lighting angle for this effect only. Then the first thing you need to do is turn Use Global Light off.
Notice now that my values have changed. Formerly I was seeing an angle of 135 and an altitude of 50 and now if I turn use global light off, I'm seeing an angle of 120 and an altitude of 30 degrees. Those are the default settings by the way. Which may make you wonder well than why the first time when we applied bevel in a bus, did it come up with 135 and 50. And the reason is because, those were the global light settings that were at work, inside of this image. Global Light is saved as part of the image file.
So having said that, I'll go ahead and drag that little cross around inside of the circle and you can see, I'm changing this one effect independently of the others. Compare that to what happens if you turn use Global Light back on. Which goes ahead and snaps those values back into place and then you start modifying the setting. In that case, you're going to change the lighting for every single effect inside of the image, subject to Global Light. And so you can see the shadows have changed their angles, both for the spider layer and for the frame.
Now we're not seeing any changes to the shadow type and that's because I had set the distance of the effect to zero pixels, so there's no possible movement. But if you take a look here, now my angle is randomly negative 146 degrees. My altitude is 32 degrees. If I switch over to Drop Shadow, its angle is also negative 146 and same with Inner Shadow. The other way to work by the way, is to switch to either Inner Shadow or Drop Shadow. And then assuming Use Global Light is turned on, then just go ahead and drag that effect inside of the image window and that's going to change all the effects as were seeing here.
Also worth noting by the way, distance is not part of Global Light. This distance value that I just got done changing by dragging the shadow around will effect the Drop Shadow and nothing more. Now, let's say at some point in time, you to ahead and drag things around and you decide, oops, you've made a terrible mistake, these are not the settings that you want at all. Remember that you can press the Alt key or the Option key on a Mac in order to turn the Cancel button into a Reset button. And then just go ahead and click on it in order to reestablish those original settings. But I think I will go ahead and make some modifications here. Just by dragging around inside the circle for the bevel and emboss effect, and I end up achieving the underlighting effect we see here. Then I'll go ahead and click the OK button in order to accept my modifications.
There's one more way to modify Global Light, and that's to right-click on the fx icon for any of the effected layers. And then choose the Global Light command. And that gives you access to those very same values that we saw inside the layer style dialog box. And that way, I can go ahead and reestablish the original settings, if I want to, of 135 degrees and 50 degrees for the altitude. Now, I'll go ahead and click OK. Now as long as we're looking at that menu, the right-click on the fx menu that it is to say, I want you to understand how these other commands down here at the bottom of the menu work.
Notice starting at the bottom we have scale effects. And if you choose that command, and enter for example, 200%, then you'll expand all of your size values associated with the layer effects by a factor of two. You also increase the thickness of your strokes. We'll go ahead and cancel out of there. The next command up, if I right-click on that fx icon, is Hide All Effects. What that's going to do is hide all of the effects throughout the entire composition. To turn the effects back on, right-click on that fx icon and choose Show All Effects.
If you want to turn off the effects for a single layer, then you right-click on the fx icon and choose this first command, disable layer effects. And then if you want to, you can turn them back on by right-clicking on that icon and choosing the Enable Layer Effects command, or you can simply click in front of the word affects to bring back its eyeball. And finally we have this command called Create Layers, which rasterizes the layer effects onto independent layers. Now it's going to succeed as long as the layer is opaque but chances are good things are going to fall apart if there's anything translucency. By which I mean, incidentally, the fact that the fill value for this layer is set to zero percent, is going to create a problem for us.
Let's try it out anyway. I'll right click on the fx icon and choose Create Layers. You'll get this alert message that's telling you some aspects of the effects cannot be reproduced with layers. Now that's not always true, you're going to see that alert message just about every time you choose this command. But it doesn't mean anything's necessarily going to fall apart. In the case of this layer, yes, things are going to go haywire on us, as you see right there. But, we now do have independent access to each one of the effects, and you can try to rebuild things or modify things, if you like. Whereas, I'll go ahead and switch over to this other image.
And incidentally, this is a gold letter effect. You can check out all of the layer effects that are assigned to it. It's all layer effects, by the way. Everything that we're seeing here. If I turn off the effects, you can see that it's just white type underneath. Anyway, I'll go ahead and turn the effects back on. If you're interested in knowing how I created this effect, you can check out my course Deke's Techniques, and look for episode five, that's 005. Anyway, this layer is absolutely opaque. So if we right click on its fx icon, and go ahead and choose Create Layers, we still get that same alert message, as you can see right there. However, when I click OK, we're not seeing any difference in the image. The whole thing is holding up beautifully, and we know have access to each on of the effects on an independent layer. And in some cases, where bevel and emboss is concerned, you'll see two layers devoted to the effect. This layer below the original layer right there, is the Drop Shadow. I'm going to press Ctrl+Z, or Cmd+Z on a Mac to undo that change. Generally what I recommend, is that before you go choosing that command, you go ahead and press Ctrl+J or Cmd+J on a Mac to create a copy of the layer.
Then go ahead and collapse the original and turn it off for safekeeping. And that way, you can always come back to it. Your final option is to rasterize the effect into the layer. However, we don't see that command in this menu. Instead, you go up to the Layer menu and then you choose Rasterize and you choose Layer Style and that'll go ahead and fuse the entire thing together into a single layer. Again, it's going to the best if the layer itself is fully opaque. And that's how you adjust global light as well as rasterize layer effects here inside Photoshop.
