- What does a dome do for underwater photography?
Domes are essential underwater when shooting wide angle and zoom lenses. A flat port magnifies objects the same way your dive mask does, and it turns into a port hole when shooting wide lenses.
- Do dome cameras have night vision?
Most dome cameras have a built-in infrared LED light for night vision, which enables them to provide high quality video surveillance. Apart from that, dome cameras are generally encased in durable covers to avoid vandalism and damage, making them an ideal option when using in exposed areas.
- What is a dome in photography?
The dome port is preferable for underwater photography with wide lenses, while the flat port should be utilized if the shot starts or ends above water, or if you need to capture a close-up with a long lens. Dome Port – The dome port is a concentric lens that acts as an additional optical element to the camera lens.
