Considering the nature of the subjects he captures, it is important for Kim to reduce the size of his shooting ear. “Instead of heavy gear, a slim, compact smartphone used to capture marine life can help reduce the distance to my subjects, reduce excessive stress on marine life, and help protect the environment,” Kim noted. . “Making a documentary with the Galaxy S21 Ultra is definitely a new challenge for me!
How to shoot underwater with the Galaxy S21 Ultra
The Galaxy S21 Ultra is an IP68 rated smartphone with outstanding dust and water resistance features for everyday use. In the event of submersion underwater, including at shallow depths, a separate waterproof cover is required in order to most effectively operate the S21 Ultra’s camera while protecting the camera from exposure to water. water at great depths.
Once you have equipped your Galaxy S21 Ultra with its extra layer of protection, the “record” and “stop recording” functions become the only settings available, which means that you will need to change your camera settings before you start. start filming underwater. For this shoot, Kim set her camera to wide-angle mode to properly capture the most active sea creatures like dolphins. Kim also opted for 8K resolution in standard angle mode to take great, close-up photos of corals.
Fine-tuning your light levels is crucial to getting the best videos from your smartphone. If you shoot using only natural light, you may end up with different results depending on the time of day. For underwater photography, the early morning and late afternoon are considered the best times of the day to take pictures, and if low light situations occur or you encounter ocean sediment, it may occur. moving closer to the subject may help with shooting.
