For the last few weeks, I've been posting a new Photoshop video tutorial on YouTube every Tuesday.
Last week, it was about how to make a poster look like it's been hanging in the sun, and the yellow has faded completely out. That's done using Smart Objects to put a CMYK image inside an RGB image.
This week, we make holes and tatters in the poster, using masks.
Next week, it's going to be making an image look like it's been painted on bricks, with matt paint.
