A bit longer Photoshop tutorial, but still very suitable for beginners, where you will learn how to carve a random text into human skin from scratch and make it look realistic.
First I will show you the easiest way in Photoshop to create even, concentric circles and after we will ad an inverted text to make it look hypnotic in a groovy kind of a way.
If you like the Lords of the Rings movie trilogy, then you might also like this Photoshop tutorial, where we will make a dramatically red sky on a random photograph.
