Whiten Teeth - Teeth Whitening Tutorial

In this tutorial we'll work on the following image and make the teeth of an old man cleaner and whiter.

Start by opening an image you want to work on.

Zoom the image to see the teeth area clearly.

Using lasso tool create a selection of the teeth area.

From image menu select adjustments>>desaturate (Ctrl+Shift+U).
Applying desaturate will remove clor value from the selection.
