One of my most popular features this year is Mikkel Aaland's 'County Fair,' so fans will be pleased to see he was interviewed on Letterman back in 1982. Today, he's offering a limited edition portfolio from the series. But Mikkel is a man of many talents, including publishing multiple titles, and he has a new eBook for photographers, currently available for free.

Spiel: "Using real world examples, best-selling author and photographer Mikkel Aaland explains the entire process of making a fixed format, photo-centric ebook for the iPad®. Aaland shows you how to use Adobe® InDesign® and the Blurb plug-in to make a cover, add images, format text, and add video and sound."
