Animated GIF master Anthony Holden shares a great tutorial on how he makes his amazing animated GIFs. He says: Making them has been so much fun, so I figured I'd try and share a little of what I know. Keep in mind that this is, of course, just one way of making animated gifs, so it's hardly authoritative or exhaustive. Mostly it's just a working method that I've discovered - and it's bound to change over time.
