Dan Margulis

Dan Margulis, an expert on color correction of photography, is author of Professional Photoshop, which, since its first edition in 1994, has become the unofficial Bible of the prepress and printing industries. His 2005 book Photoshop LAB Color: The Canyon Conundrum and Other Adventures in the Most Powerful Colorspace revolutionized workflows for many Photoshop users, and became the top-selling book in the entire computer/internet field.

Formerly a professional prepress manager with over 20 years experience heading electronics departments at high-end trade shops, he went on to offer hands-on color correction classes in the U.S., Canada and Europe, in four different languages. In September 2001, Dan was one of the first three persons named to the "Photoshop Hall of Fame" of the National Association of Photoshop Professionals.

Now semi-retired, he still teaches the occasional class. HiIs latest books are Modern Photoshop Color Workflow (2013) and, in 2020, a complete remake of M.E. Chevreul’s classic On the Law of Simultaneous Contrast of Colors.
