National Geographic Traveller India has partnered up with Samsung India to capture some stunning images of marine wildlife. It involves a marine life expert capturing her underwater adventures using nothing but a Samsung Galaxy S21 Ultra. We get to see several Galaxy S21 Ultra camera features in action, such as 8K videography, low-light photography and the ability to capture 33-megapixel stills while recording an 8K video. The following video walks us through the adventurer's journey through the ocean, which began in Fuvahmulah, the shark island of the Maldives.

Although the Galaxy S21 Ultra has an IP rating and can be submerged underwater, attempting to do so in a marine environment would almost certainly ruin it due to the high atmospheric pressure and salinity. That's why the smartphone is encased by a protective layer. That could, in theory, affect the quality of images because it adds an extra layer for light to refract through. That doesn't seem to have bothered the Galaxy S21 Ultra a whole lot, as it still managed to capture some stunning images of the ocean.
Our Galaxy S21 Ultra review determined that the quality of 8K videos recorded by the smartphone's camera is only marginally better than the ones shot at 4K. Perhaps National Geographic has better use for 8K footage than the average consumer, given that they are used to shooting at the resolution all the time with their standard equipment.
