Video shot using a camera. Shallow coral reefs and clear water. Summer. Red sea. At a small depth. In Diving With A Mask And Snorkel. Used easy attachments. Day and bright light. In rare cases, used hinged stabilization. In some cases, the video was made with a tripod. Exposure and light balance automatically. The video has not been edited, that gives enhanced capabilities to the end user to adjust the clip myself.
