Smart Object Overview
our next topic will be smart objects and smart objects have the potential of completely changing the way you think about Futter shop, depending on what you do now in previous sections of Photoshopped, The Complete Guide, we've used smart objects. We use them once when we're playing filters, and so it's very nice way of doing it. But let's jump in and really dig deep into the concept of a smart object. Some. I'm going to duplicate this image here by going to the image menu in choosing duplicate when I duplicated, I'm gonna call it not smart. So you know that that version is not going to be utilized. Smart objects. Then we have two versions of that image open. I want to be able to see them side by side, so I'll go to the window menu, choose, arrange and choose to up vertical, which will show the images side by side. And at this point, I'm going to take the image on the right. Uh, and I'm going to go to the layer menu, choose smart objects and say, convert to smart object. Now when I do t...
hat, watch what happens in my Layers panel. If you look at the little thumbnail picture. If that layer and you look in the lower right corner of it, When I convert this to a smart object, you'll see an extra icon appear there. Now. The first time you ever do that, you might get a little warning that comes up, and it just tells you something about, um, if need to edit the contents of this to double click on the layer. Just see aware, if something comes up the very first time you do that, there should be a don't show again check box. I suggest you turn it on and click OK, because after this lesson you'll be quite versed in smart objects. So now the image on the right is a smart object. The image on the left is not. They look the same, but they're not gonna always act the same. Whenever you create a smart object, it is like taking your image in putting it into a protective sleeve. Imagine it's something like a Ziploc bag, and by putting it into a smart object, it's going to protect the original contents of that layer. So anything I do to it from now on will not be able to to change the original contents. I can still change the look of the picture, but I always can get back to the original look. So first I'm gonna work on the not smart version and I'm gonna unlock its little layer here because it's a background layer and there's only certain things I can do to the background. If I clicked the lock symbol, though, I could do anything to it. And what I'd like to do here is first I'm going to apply a filter to this, and when I filter it, let's see. I'm gonna come down and maybe just sharpen the image and all kind of over sharpen it so it looks really sharp. Click OK, and if I zoom up on it and I choose undo, you see before and after it's over sharpened. Then I'm going to scale and rotate the picture to scale and rotate something. Usually I go to the edit menu and I choose free transform or I type will the keyboard shortcut command T control team windows and I'm going to scale this really small like that small. It also rotated and press return or enter to indicate that I'm done move into the middle of my document. So if I zoom in, that's all we got. Then I'm gonna do the same thing to the image on the right. That's the one that is a smart object. With that one, I'll go to the filter menu. I'm going to sharpen it in o apply in Sharp Mask. It looks like it's remembering the settings I used on the other one, so just click OK, and then I'll go to the edit menu and choose free transform. This is one of those things where you got a warning that you just choose. Don't try again and click, OK, and I'm gonna make that again very, very small, much smaller than that. And I'll rotate it, press return or enter. So now we've down approximately the same thing to both images. I don't know if I haven't exactly the same on both. I doubt it, but it's close enough. The main thing is, the image on the left is not a smart object, and because of that, it does not remember what the old version of the image looked like. Especially if I were to save this image, close it and open it a month later. Sure, because right now I could choose undo to get it back. But imagine it was saved, enclosed so that it doesn't retain any kind of a history. Well, now I'm gonna take that image on the left. And let's say I didn't want it to be quite that small. So I go to the edit menu, I'll choose free transform, and I'm going to attempt to scale it up when I scale it up. It does not remember how much information it originally contained. So if I attempt to get this to fill the majority of my screen, it's not gonna regain any of its quality. And if I attempt to straighten it, there's nothing that's gonna help me. Make sure that it's perfectly straight, and that is not at like a one or two degree angle compared to what it was before. I'll get it up there. I'm gonna press returner enter and you'll see how terrible the results look. Take the image on the right, though it's totally different because it's a smart object, which means the original contents of that layer, you are completely preserved in everything I do to this image will always be calculated from the original contents of that smart option. What that means is when I go over here to edit and I choose free transform first off, I doubt you can tell right now, but it's starting off differently. Do you notice that the transformation handles that are on this match the angle of this object? Whereas when I did it to the image on the left, they were straight. It never knew that I ever rotated the image in the past. But here, with a smart object, it knows that I've rotated it. And if I look up here in my options bar, I can see what angle it's been rotated to. If I select the number for the angle and type in zero impress return, that should straighten it out. So now it's back to the way it used to be. Also in the options bar. It tells me exactly what size this had been scaled to, and I could just select that and type in 100 and press return. And that's going to end up bringing this back to its original size because the transformation I've applied is just thought of as a setting attached to the layer. It's not actually changing the true contents that layer in, so I can always bring it back. But when I bring it back, I look at it and I'm like, That looks overly sharp and I'd really wish I wouldn't have sharpened the image Well, if you look in my layers panel since this was a smart object, when I applied a filter, it was applied as what's known as a smart filter. And if I would like to remove the effect, I could either turn off this eyeball were just drag this to the trash and I would see the version of it That's not sharpened war. Aiken double click on the name of the filter that's in my layers panel, and it will open up the sharpened screen here, and I could find tune the settings to get it to be more appropriate for this image. Because anything I do to that file is not going to harm the original contents that was put into the smart object, and it will always be calculated from that original contents and therefore I can easily scale it back up to original size. Rotate it back, change any filters that have been applied. It's much more versatile, whereas the image on the left just looks terrible. So what that means is, any time you plan and combining multiple images together, let's say you're going to design a little layout that's gonna show maybe six pictures, and you're going to scale them down and rearrange them in various areas. It would be best if you were to start with smart objects, because then let's say you scaled down those pictures and you started placing them side by side. And when you were done, you decided, well, they're a little too small. You want to scale them up to fit some more space. Well, if you do that and you don't have a smart object, anytime you scale things up, it's going to make your image look softer. And that's like what you're seeing on the left side of my screen. That's just an extreme example of it, but if it was a smart object, the quality would still be there
