Biennials are Competitions and Exhibitions, each in a particular medium – Colour Prints, Monochrome Prints, Projected Images, Natural History. Within the medium, each country chooses a subject matter theme, and the judging includes an assessment of coherence within the theme. Countries offer to host Biennials which are major events with 500 to 600 photographs exhibited. FIAP Medals and other awards are made to the entrants.
