Every January, a panel of judges select the best images entered in the online photo contest from the previous year. Gold, silver, and bronze medals are awarded for the top three from each category in order of merit.
There are 17 categories, including Freshwater, Sharks, Wide Angle Marine Life, and Wide Angle Wrecks.
