The Chilterns Association of Camera Clubs (CACC) holds two annual Championships, for prints and projected digital images. Each Championship is open to all clubs in the CACC. Clubs enter as a club (not individual authors) and may enter either or both Championships.
For each Championship, the club submits 15 images. These are shown individually in random order and scored on their standalone merits, not as part of a panel. Three judges each score the images out of 5 – making a top score of 15. Scores are totalled for each club to determine the winning club.
There are awards for the winning clubs and the best individual images. In addition, the Print Championship and the Projected Championship determine which two clubs are invited to represent the CACC in the PAGB InterClub Print and the PAGB InterClub Projected Championships respectively.
