I've blogged about our friend Glyn Dewis before. He's a talented UK-based photographer that also posts lots of free amazing Photoshop tutorials with straightforward tips. Recently he posted a video on how to enhance eyes, which is extremely important in portrait photography, and how to make fake beards using noise and blur tools. The results are impressive!
According to Glyn: "In this episode I start off showing you a fun technique for adding stubble / facial hair; a technique I learned from UK Retoucher Steve Caplin but then show how the exact same technique can be used to enhance eyes."
If you want to learn more from Glyn, he has a new full length downloadable tutorial "The Editor," which shares his shooting and post-production tips, which I have also ordered for myself!
