58 North has announced that the free iPad digital photo book app, Pholium, now offers the highest-quality hardbound photo book printing capabilities. By including QR codes in Pholium photo quality printed books, viewers can experience the same interactive sound and video contained in the eBooks. When a user hovers over a QR code with any smartphone or tablet, they are instantly directed to the multimedia content. “Printed photo books are great, but they are limited to whatever is on the page,” said Robert Sinclair, co-founder of 58 North. “With this update, we’re giving life to printed photo books and allowing our users to tell and share a richer story through multimedia assets.” The lay-flat printed Pholium books are available with glossy or matte finished image wrap covers and can contain up to 158 photos, audio captions and video links. The up to 80-page printed books start at $42 (8-inch) and $47 (10-inch). Shipping is included.
