Underwater Settings & Technical Matters
Many photographers start out worrying about technical matters too much. Just get out there and shoot! Most cameras work great right out of the box. Stick it on manual mode, find some subjects, and start shooting. You'll be fine, and you'll be having fun. It only takes a minute to learn how to change your shutter speed and aperture. Still, at some point you should know your camera and it's capabilities. Read the camera manual cover to cover.
Just so you don't get the wrong idea, I think it's very important for an underwater photographer to have a solid knowledge of aperture, shutter speed, ISO, and their effects on underwater photos. Thinking about these variables should become second nature.
- Shutter speed
- Aperture and depth of field
- Shooting in RAW vs jpeg
- Recommended underwater settings for macro and wide-angle
- More technical matters such as sensor size and dynamic range
Application to underwater photography is emphasized. A solid foundation in these basics can only help your photography.
