Equipment used

Equipment Usage description Data types Datasets
Digital Camera A Canon Powershot S120 was used in conjunction with the associated Ikelite underwater housing to capture still images. Camera settings varied depending on underwater conditions but were manually adjusted. Shutterspeed was set to a fast setting (minimum of 1/250) to account for moving objects. ISO was adjusted based on light availability on each dive. Aperture was set to a low setting and usually not adjusted. All images were shot in RAW to allow for ease of post-processing. Manual focus was used. Photo, Video (no data reported)
