Photoshop CS4 for Photographers is an essential course for any digital photographer who wants to master the software's vast array of image enhancement techniques. Professional photographer and instructor Chris Orwig uses his own compelling images to demonstrate how the power of Photoshop can make photographers more passionate about their work. He covers many aspects of the application, such as working with RAW images, using curves and levels, making images snap, and enhancing bland photographs by converting them to black and white. Exercise files accompany this course.
In the next few movies, you are going to learn a valuable technique that will help you brighten and whiten teeth. Now we are going to work on two images here, so we can talk a little about how we can make selections. The first image we are going to work on is corwig_ andreina. Just go ahead and double-click that file to open it up in Photoshop, press F to go to Full Screen View mode and here we have this nice portrait of one of my good friends. And I like the warm tones, I like the expression and everything. I want to zoom in on this image, so I'll double-click the Zoom tool. Now when I double-click the Zoom tool, I notice that while this image has a nice warm tone, it might be kind of nice, it might help the photo just a little bit to whiten up those teeth a bit. And that's especially true because we have a little bit of a warm cast in this image.
So how can we select the teeth? Well, we can select them in a number of ways. Let's go ahead and try Quick Select. What we can do here is click and paint across the teeth. Now once you click once, you want to hold down the Option key on a Mac/Alt key on a PC and click to paint around the skin and the lips. And what you are actually doing here is educating this tool or telling this tool that you don't want to select these areas and then go ahead and paint across the rest of the teeth. Now you have a little bit better of a selection. Now will this selection be perfect? Well no. But it will be a pretty good starting point. All right well there we have a pretty decent selection. The next thing that we are going to do is go ahead and click on the Adjustment Layer icon and choose Hue/Saturation or from the Adjustments panel, choose good old Hue/Saturation.
Now you may think, yeah just desaturate right, well that looks horrible, absolutely horrible. So let's reset that back to zero here. What we want to do, go to our Yellows and with that selected we will grab that target adjustment tool and we are going to click and drag to pull out a lot of the yellow from those teeth. Now at first glance, we are thinking, okay, it's looking better but still the teeth are going a little bit gray right, we can see that, it's almost colorless and if something becomes colorless then it looks dead or it looks lifeless. So we don't want to go white but we do want to brighten and whiten a bit.
So I'm going to go ahead and lower the yellows, now I lower them significantly. Next, I'm going to go to my Master channel here, and I'm going to just brighten these up just a touch as well. All right, well let's look at before and after. Before and after. And you know a lot of times, people stop there and it doesn't looks very good, it looks okay, but it doesn't look great. How can we get these teeth to look great? We will click and drag this to the New Layer icon or press Command J on a Mac, Ctrl+J on a PC. And in this Top layer, we want to take this to a blend mode of Soft Light, that's going to bring back our overall contrast. Let's look at our before and after with that last layer. Yeah that's the one I'm talking about, right.
So here now we have our overall before and then after. Now there maybe a few little areas that we need to clean up in regards to our mask and we may need to back a few things off. So let's go ahead and go back to this original layer here. What I would like to do is to go back to the Hue/Saturation Adjustment and then just make a real drastic adjustment and then I know this looks bad but stick with me for a moment, let's zoom in. And now when I zoom in, I realize Gosh! My mask wasn't quite horrible, so I'll click in the Mask Layer, paint with black, got my Brush tool; left bracket to make that brush tool smaller. I'm just going to go ahead and paint away this area. So I'm limiting this adjustment to those areas. And I needed to do that in order to really see the problem area and I'll go ahead and fix those up just a little bit there, and that looks nice.
Okay, well now that we have done that we can take our Hue amount back to the default of zero and look at before and after with that mask, perfect. Now at this Top layer, the mask isn't very good. All I need to do, hold down the Option key on a Mac/Alt+ key on a PC, click and drag that to the New Layer icon, replace that. Yes. And now we have a good mask on both layers and here we can zoom out a little bit. And then we can modify the overall brightness with this one, also the overall whitening there and then the contrast with this top layer again, we can go all the way back or bring it up. And we can find a teeth whitening which really looks good and supports the image.
Finally, I want to zoom out all the way. So I can step back a little bit and say, "Am I going in a good direction?" Here is my before and after. You know what, I think those teeth look really nice. The thing you want to be careful of, when you are whitening your teeth, is you don't want to whiten them so much that that's to all people notice and with this image our before and after. I think we did a pretty good job. Let's move on to the next image, we will do that in the next movie.
