Every year since inception, there have been image disqualifications due to competitors breaking rules.  Please read carefully.

• The judges will disqualify any images which in their opinion have involved handling, placing or interfering with wildlife and so not observed the BSoUP and Marine Conservation Society Photographer’s Code of Conduct.
• Only 2 images can be entered in the main competition, plus a third if you also enter Mankind’s Impact on the Environment category. Competitors can use 1 open category and/or 1 restricted category camera, with any number of lenses during or between dives.
• All images except Mankind’s impact must be taken under water or part underwater in salt or fresh water natural environments. Images from swimming pools, aquariums or anything that contains captive flora or fauna are not eligible.
• The benefits of allowing remote submission of images needs an element of trust. Personal integrity and respect for other competitors is expected. No system of electronic validation is entirely secure, but reasonable measures are taken to assure the validity of entries.
• There is no limit, other than those imposed by sensible diving practices, to the number of dives that a competitor may make within the 24hr window, provided that they make the image submission deadline.
• Automatic and manual in-camera processing is allowed. In-camera processing, i.e. changes made post image capture, should be consistent with the spirit of the competition; it should restore what was observed underwater at shutter release, or combine multiple images in an artistically-sympathetic way.

Out-of-camera processing is permitted to the following extent:

• Cropping to improve composition.
• Global (whole image) adjustments that are judged to restore the colour and contrast observed at image capture are allowed and encouraged. This includes colour balance, exposure, contrast, tone, highlights and shadows, clarity, noise, vibrance, saturation and lens distortion corrections (including lens vignette corrections) or any similar global adjustment provided by any software package.
• Local adjustments that add or remove specific parts of an image are prohibited, for example any type of cloning, including back-scatter removal, partial image blurring or artificial vignettes.  RAW files are mandatory and they will be validated.
