DivePhotoGuide has developed a unique set of comprehensive interactive underwater imagery calendars, representing nearly every underwater photography and/or video competition in the world.
Among the details on each competition include the usage rights you are granting the competition for your entries or winning images. We do suggest reading the official guidelines and rules before entering any competition, as we can not guarantee that the rules have not changed since the competition was posted to our calendars.
Dates highlighted and listed below represent the deadline dates for each competition.
Good luck!
