About our guest:

David Biedny is a legend in the Photoshop and Macintosh industries. He was the primary author of the very first book ever written on Photoshop, “The Official Adobe Photoshop Handbook” (Bantam), and his “Photoshop Channel Chops” (New Riders) is a cult classic, the most collectible computer trade book of all time. David was also right there at the beginning of Apple. He got his first Mac on January 24th, 1984 and instantly became the go-to Mac troubleshooter for the first generation of Mac users in New York City. Since then, David has taught and lectured at the School of the Visual Arts, NYU, Stanford University, San Francisco State University, the Seybold Seminars, and is currently a Lecturer in design at the Yale School of Drama, where he teaches core digital media courses for drama students.

Working at Industrial Light and Magic, David Biedny created digital effects for motion pictures including “Hudson Hawk”, “Terminator 2: Judgement Day”, “The Rocketeer”, “Star Trek 6: The Undiscovered Country”, “Hook” and “Memoirs of an Invisible Man”. In recent years, David has created animation and video projections for theatrical productions, working on shows including “The Good Body”, “Drowning Crow”, “Oldest Living Confederate Widow Tells All”, “Tommy Tune: White Tie and Tails”, “Nixon in China”, the Simon & Garfunkel reunion tour, “Arjunas Dilemma”, the Chris Rock 2008 New Year’s Eve show, and the most recent production of Tony Kushners “Angels In America”.

The list just goes on and on. What an honor to have David Biedny with us on this episode of TheFIX.

Where's Jan?

Jan recently celebrated publication of her 40th course. Check out her latest courses:


  1. The fix 024 with David Marx was fantastic. I haven’t learned as much in an hour for a long time!

    1. Yes, it is, at least the vast majority of it is, as I mentioned on the show, it was written with core issues in mind. Many find the math in the blue screen chapter worth the price, it has been duplicated nowhere else.

  2. What a treasure trove of information!

    I really like to learn about computer hardware and software history. My first encounter with computers was in 1969.

    The frequency separation concept makes perfect sense to me because although I’m still a relative newcomer to full Photoshop, I have had a surround audio system with a separate subwoofer since the turn of the century.

    I’m going to be coming back to view this episode several more times to get the fine details of David Biedny’s method and adapt it into my workflow.

    2 other photographers I would like to see on the Fix in the future:

    Tim Grey

    Jared Polin

  3. Call me dumb, but it’s the first time I actually understand Frequency Separation. What a great instructor, it just makes sense and it’s so simple. This is $$$ information for free. Thanks Jan.
