Issuu is an online conversion system that converts PDF files so that they can be read on the internet via web browsers. It's really eye-catching to have one's portfolio in a digital magazine with its pages flipped just like a real book or magazine.
The conversion from photographs to a PDF document is a cinch with Photoshop, and then these can be uploaded unto Issuu for conversion to a digital magazine or book. It's a simple process and it's free.
However, here's an excerpt of Issuu's terms that you need to consider before availing yourself to this service:
"By distributing or disseminating Uploader Submissions through the Issuu Service, you hereby grant to Issuu a worldwide, non-exclusive, transferable, assignable, fully paid-up, royalty-free, license to host, transfer, display, perform, reproduce, distribute, and otherwise exploit your Uploader Submissions, in any media forms or formats, and through any media channels, now known or hereafter devised, including without limitation, RSS feeds, embeddable functionality, and syndication arrangements in order to distribute, promote or advertise your Uploader Submissions through the Issuu Service."
