I recently watched one of Deke McLelland's 'Deke's Techniques' video tutorials in which he shows you how to overlay a textured pattern onto a face, and I fancied giving it a go.
Having no other faces available, I had to use my own. With the iPhone I took a self portrait and a photo of the pattern on my yoga eye bag. I then combined the two images in Photoshop, following Deke's directions.
I'm really pleased with the way the experiment has turned out. I'll have to try it again some time with some better resolution images.
