Here is another article of our “GIMP tricks” series. This time you are going to learn a simple trick: how to make your teeth look really white on a photograph. By the way, perhaps it’s the right time to visit a dentist?
First you will need an image of yellow teeth. Here you can download the one I used in this tutorial: The jaw image
Open the image you have downloaded or the one you want to correct. Toggle the view to “QMask” by pressing the little square shown in the picture below.
qmaskThe whole image should become red. Don’t be afraid, everything is OK.
Use the “soft” brush - Circle Fuzzy (here you can use 19 as the value). As a foreground color, choose white. It is used to mark the selection on the mask.
Now outline the tooth as it is shown in the picture below.
