Photoshop Tutorial - Whitening Teeth

In this tutorial we are going to show you how to “Whiten Teeth” with just a few very simple steps. As you can see in this image the teeth look very discoloured.

The first thing you need to do is make your “Selection”. In this tutorial the “Magic Wand Tool” was used, but you can use the “Lasso Tool”, “Pen Tool” or any tool you want to make your selection with.

If you want to use the “Magic Wand Tool” then you need to select it from the right handside. Next you can alter your “Tolerance”, the setting used for this was 32.

You now need to make your first selection, to do this you need to click over the teeth and “Hold Down Shift” and continue clicking until all the teeth are selected.

Now you need to smooth out the selection a little, to do this we need to use “Feather”. You need to Press Select > Modify > Feather and have the Feather Radius set to 3pixels. The reason we are doing this is so that when we have our colour corrections they’re not as sharp, this way they won’t look unnatural.

The next thing you need to do is add some adjustment layers. So head over to your “Adjustment Layers Pallete” and click on the black and white button, we are looking for the “Hue and Saturation Button”. In Photoshop CS3 or below the “Hue and Saturation Button” can be found in the tabs across the top.

If you are using Photoshop CS4 it will appear as a panel, but if you’re using Photoshop CS3 or below this will appear as a Dialog box.

Inside the “Adjustments Layers Tab” you’ll see 3 settings, the first setting you need to change is the “Saturation”. You’ll need to decrease it to get rid of the discolouring on the teeth. Then increase the “Lightening” setting just slightly.

At this stage the teeth look good, but you’ll notice that we need to get rid of the shadows in the middle of the teeth. Getting rid of these shadows will give your teeth more definition and make them stand out more.

You need to add one more “Adjustment Layer” then hold down “Command or Ctrl” on the “Adjustment Layer” to make that selection once again, then you need to select your “Adjustments Levels”.

Then very simply drag your midtones to the right slightly, this will darken it up a little. Then select the highlights and drag it to the left. You’ll have to play around with the settings here, you’re looking for something which looks very natural.
