70. How to Realistically Whiten Teeth in Adobe Photoshop
Hi there. This video is all about teeth whitening before after before after. It's easy to do and the cool thing about it is once you've done it once you can reuse it over and over ready. That is the after ready before after before after. It's a nice retouching trick. Let's learn how to do it now in Photoshop. Alright. To get started from your 10 retouching folder. Open up teeth one and 2. Let's start with number one to get started. Let's make a real just basic selection. So I'm going to use the quick selection tool zoom in the brush size. I'm just going to pick the teeth but not the gums, but we're not spending too much time here. Okay. There is it's easier just to get most of it done and then brushing the edges using your brush to a little bit later on, we'll get the gums don't get the gums, but again, we are going to fix this later on so don't worry too much about it. All right, most of the teeth. Alright, first up is we need some consistent color because there's bits of whites and b...
its of yellow. You might have darker bits of brown in there as well. So what we need to do is get some consistency. Easiest way is to go to your adjustments panel. We're going to use the hue and saturation and what we want to do is colorize it. It's kind of weird, right, but at least it's a consistent color. We don't want to be consistently pink. So crank up the saturation until you find you want a yellow color. I know we're just trying to get rid of yellow, but I'll show you what I mean in a second. So if you find a, just that kind of a warm yellow, just something like that and then crank the saturation weight down because if you go to zero saturation, nobody has that white teeth or at least great teeth. So you need some yellow in there and that's the trick because it's not perfectly white, there needs to be some yellow in there, Let's turn it off. So lots of yellow and inconsistent yellow, whereas just a little subtle hint of the other. So there's one part. Next part is we need to make them more white or at least seem more white. So what we're going to do is grab the, grab the rectangle tool, pick a full color of white and just make sure you draw a rectangle across the whole lot of the teeth covering it up. I want to mask this white into the teeth. So what I could do is hold command on a MAC or control key on a PC to get their selection and have like two selections going. So I've applied a layer mask to this one as well. But the trouble is we'll end up having to adjust a couple of different layers, so it's a stage like this where it's really handy to have this layer mask on a group and just have everything inside it. We're gonna have three layers levels this white rectangle in this human saturation, we'll just get them all to use the same mask. I'm going to undo that. I want the selection, which is cool and I want to delete that layer mask because I've right clicked ID. We'll sleep both of these. I had this little folder down here put into a group and now apply the layer mask to that group. Just means that these guys here don't need their own individual masks that doesn't look amazing. We're going to fix the edges. The first thing you want to do is have a rectangle selected and we're going to play with a blending mode. Okay, so remember on one of them then make sure I'm on my move to hold shift. Hit plus, and just kind of work your way through until you find one that you feel works. It's probably going to be soft light. It's not always though. So I guess I want you to have a work your way through and find one that works. Soft light here makes it nice and white. Probably a little too strong, so we're gonna lower down the opacity again, we're not worrying too much about the edges were going to feather those out to check how far we've come. Who remembers what I can click here just to turn that layer on by itself and turn all the others off, you remember? Yeah, you do if you're on a Mac, it's option and give the eyeball click or on a pC. So definitely more white. Not super believable just yet. We're gonna do two more things. One of the levels we just need to increase. There's just kind of, it's too washed out in lots of places here, but let's create an adjustments levels And in here we're just looking to just maybe bring up the blacks a little bit just so that there's a bit more kind of contrast in the teeth. Don't wanna go too low with the mid tones. Let's keep those nice and high and maybe a little bit higher here and the highlights, it's up to you do this levels need to be turned down a bit and maybe this human saturation. Okay, does it need less of the yellow? Maybe just a touch before we go and adjust all three of these. Let's kind of blend the edges a little bit better. You could go and see how well you go with just selecting the mask, going to select the mask and to see how you go with feather. I'm probably gonna start with feather and then brush it in cocaine. Somebody better undo. Redo. That might be enough for you, but you might have teeth in the background here that um let's whole let's turn this one on and off. I'm okay with it actually. I might feather it a bit more but I also want to show you. Let's just work on the mask with the brush tool. Make sure in your brush tool here, I was using a special effect brush. Go back to general brushes and just pick the first one and I have my flow 100% and maybe turn down the opacity a little bit. What I'm trying to do in here is there just needs to be a little bit more of a realistic blend between the gum and if you, your selection was really bad, you probably have to go and spend a bit more time. Just kind of making sure this kind of transition between the teeth and the edges here. Just working the edges just a little bit to have a little bit of realism between the the transition of pearly whites to this kind of more hiding underneath the lip. It should be a little darker. Maybe not. These guys definitely here in the gums you can see the gums ended up going quite white. What I'm going to do is to get into this little area here. I'm going to go to 100% capacity and I painted out cape toggle the foreground and background color over here using the X key and just paint it back in. It's easier to get into the corners that way. Same with you X painted out X again to toggle it back. So black is my foreground. I'm happy enough Now we've got our blend working better. We've got a, we've got to kind of walk around your office or your lounge wherever you're at because after looking at it a while, it just, it becomes really hard to know whether you've gone too far or not far enough to go make a cup of tea, come back and then look at it and go, hmm, is this believable if you're finding it's not after a little walk around the room, come in and start working through the levels, click on the levels part and decide do I need more of this? Less of that does the whole layer need to be turned down in terms of the capacity? The white triangle here. Okay, we pick soft light. You might try a different blend mode capacity might be needed to turn down a little bit and under human saturation. Does it need more yellow or less yellow? Two great. All right, let's go for the big reveal. Let's hold down option, click on the eyeball. Whole lot better. Find a closed one eye. I'm not sure why when I'm over. I'm kind of checking it out. Yeah, it's looking good. Close one eye doesn't look good. one eye. The other eye, I doubt that helps. That's what I do. Now, once you've spent a bit of time creating these three little layers, you can totally reuse these. So what we're gonna do is grab the group. Okay, And this is going to be my teeth whitening layer. And let's say teeth to this is a bit more of a realistic example. I guess nobody gets that sort of close in. What you end up with is kind of generic. This photograph is not amazing if you zoom in it's kind of a little bit out of focus but the teeth need to be fixed okay. Tidied up but not terrible teeth but they could use a lick of white paint. Move to select the group, command C command V. It's brought through that group of whitening. All we need to do is right click delete the land mask, make sure that this white box is over his teeth. You might just make that white box huge so that the next image you use you don't have to be as specific. And what we're going to do is let's click on the background layer, we're going to add a layer mask and a cool little trick is instead of like adding a layer mask and then trying to paint it all out or fill it with black. What you can do is as you click layer mask, hold down the option key on a MAC OK on a pc and it just applies a layer mask. But the inverted version instead of a weight mask, it's a black mask. What we can now do is grab our paintbrush And either start with the quick selection tool or just start with a brush. Like I am picking a hardness that kind of matches the edges of the teeth here using white is my foreground color. My capacity is up 100%. I might turn the opacity down to something like by tapping five on my keyboard and just slowly but surely working the teeth. Okay again, we're gonna have to probably do some adjustments okay levels and the human saturation to make this thing believable, but you've got all most of the work done in the group, Okay, and there's just some tweaking, you need to do, looking loads better already, Okay, remember the r key. Okay, you need to move it around alright. Escape to rotate it around, I'm leaving just a little bit of yellow in the corners there, I don't want to get too far removed from your life, A whole lot better on off and now you can go through, drop this down and decide do I need to mess with the levels a bit more, maybe lower them down a little bit, raise them up a bit, Okay, make your tiny adjustments too much do that a little bit human saturation, I'm happy with how the saturation is, and click on off on off and that my friends is how to whiten teeth using a mixture of huge saturation, a big old white layer and levels now with levels that sometime is optional. Okay, it doesn't always need it, it didn't these two examples but lots of times it doesn't and if you keep them in a nice little group, you can reuse them on different documents. Alright, Friends, I will see you in the next video.
