Believe it or not, we can actually whiten teeth with the Adjustment Brush, and that's what we're going to take a look at here. This particular photograph was captured by good friend of mine, Michael Costa. Michael, thanks a ton for the use of this file. I love the colors here, the expression, and the image has a bit of a warm cast, which I like, but it makes the teeth of little bit yellow. So let's say we want to brighten or whiten those teeth up. We'll go ahead and zoom in on the image, and then we'll select the Adjustment Brush by pressing the K key. Next, what we want to do is turn on the option for Auto Mask.
We can do so by clicking on the check box or by pressing the M key. We're also going to need to see the Mask to make sure we're really working on the teeth, so let's press the Y key, and I'm going to choose a color which is going to really stand out. I'll go ahead and select a bright green. Now this bright green color won't look good, but it will be great as a Diagnostic tool to help us determine how our Adjustment Brush work is actually working out. All right. Well, what do we want to do lighten? Well, we want to de-saturate a bit, brighten a touch, a little bit of Exposure, and then I'll go ahead and add just a touch of negative Clarity and a little bit of Contrast there.
Now these settings won't even be close to perfect, but it will be a good starting point. Let's zoom in a little bit closer, just so we can really focus in on the teeth. Now with our Adjustment Brush, we'll change our Brush Size. We want a nice amount of Feather, not too high there. Flow, let's bring that down a bit. Next, we're going to simply paint over the teeth, and we're going to really focus in on what the crosshairs are touching. In this case, just the teeth, and this is making a pretty good selection, so far no problems yet and if any problems come up, we can always erase from this Mask by holding down the Option or Alt key and painting.
Now when we get down to these smaller teeth it may be a little bit more tricky. We'll see if we can pull it off though, and again, just really focusing in on those crosshairs. All right. Well, for the most part, pretty good. Only thing I need to do is paint in between the teeth here, to do so, I'll turn off Auto Mask. Let's use that shortcut. It's the M key. Turn that off, and now I can paint right in there. I can also work on a couple of these little edges and just touch this up a bit. The only downside with using Auto Mask is that sometimes it creates a little bit of a jagged edge, so all I'm trying do is soften up that jagged edge there.
Okay, well, let's zoom out, Command+Minus or Ctrl+Minus. Next, we don't want to see this green color, because this isn't helpful at all. So we need to hide that Mask color. We can do so by pressing the Y key. All right. Well, we also have this distracting pin. Press the V key. That will then hide that. Let's evaluate how we're doing here. Click on the Preview check box. Here we have before, and now here we have after. Already those teeth are looking better. Let me zoom in on them, so you can see for yourself. We have a before and then after.
To modify this further, we can lower the Saturation amount. We can also work with the overall Exposure. Now a quick word of caution. You can make teeth look really bad as well, go ahead and darken those teeth, and that's not very flattering. So you just want to be careful with this and find just the right sweet spot, so you're not making these pure white, but you are whitening the teeth. Again, here we have it, our before and then after, nice teeth brightening and whitening, and let's find just the right spot for this image and then zoom out.
Evaluate this one more time. Here we have it, before and after. Nice work on the teeth whitening.
