AI Press and IFPO are associated websites and organizations.
AI Press and IFPO are associated websites and organizations. Essentially they are different "programs" that are part of the same larger organization. Again, the website is dated and it's a bit confusing to find some things. They have however been in existence for quite some time. You may find that they are geared more to a more traditional member base, with more photographers and less people involved with new media (blogs, vlogs) etc.
