We ever talked about one way to whiten teeth, that is, applying levels and HSL. In this tutorial, I want to show you the other way, which is easier than before. Sure, the two ways all have its merits. You can use one of them according to the actual situation.
The following is the contrast picture before and after change.
First of all, press Q to edit selection as Mask and choose Bush Tool to paint on the teeth.
Choose Inverse to select teeth selection.
Next, Select “Adjust > Curves”. Look, are the teeth whiter than before?
If the result is not what you want, you can select “Adjust > HSL”. I make some change as the following.
Press “Ctrl + D” to deselect the current selection. Now, the effect comes out.
