This 826.9MP Photo is the World’s Largest Underwater Panorama


Greater than two years after really capturing the picture, Brazilian photographer Marcio Cabral has formally been granted the Guinness World Record for the “World’s Largest Underwater Panoramic Picture.” The unbelievable 826.9MP {photograph} is made up of 28 photographs that each one needed to be taken from the very same spot… whereas diving… underwater.

The {photograph} was captured on August 31st, 2018 in the Lagoa Misteriosa (translation: mysterious lagoon) in in Jardim, Mato Grosso do Sul, Brazil. Lagoa Misteriosa is a clear “lake” at the backside of a sinkhole so deep that no diver has ever discovered its backside.

For the photograph itself, Marcio tells us that he used a Canon 5DSr with a 16-35mmn f/four VR lens inside an Ikelite housing with an 8-inch dome. He additionally used an internal correction lens, which is designed to right picture aberration and distortion brought on by wide-angle lenses when capturing under a dome port.

To set the new file whereas creating as partaking a picture as potential, Marcio used a customized ISO to enhance dynamic vary—his ISO ranged from 200 at the zenith to 800 at the nadir the place its darkest—and employed a number of fellow divers as “fashions.” For reference, the backside a part of the picture reveals a diver inside a spherical “bubble.” That diver was floating round 20 meters (~65 toes) whereas Marcio shot the pano from a depth of about 18 meters (~59 toes).

All of the photos used needed to be made in the similar place to keep away from parallax errors—24 particular person frames taken from the similar location, plus 2 Zenith photos and a pair of Nadir photos. Clearly there’s no strategy to seize the full scope of the picture in a single flat 2D shot with out leaving one thing out. Even Marcio usually shares it as two totally different photos: an equirectangular projection and a zoomed in piece of just a little planet projection:

Nonetheless, you can flick thru the whole photograph on this interactive model from 360cities. If in case you have VR glasses, put them on and faucet the VR icon in the prime proper to get the full expertise:

In case you’re questioning why it took so lengthy to validate this file, that’s as a result of (for apparent causes) there wasn’t an official “adjudicator” current when the {photograph} was captured. In response to a Philip Robertson, an precise Adjudicator at Guinness:

Data can take a good period of time to collect proof for, and having witnesses log off […] The proof evaluation course of also can take a number of months, relying on the complexity of the proof and file class.

Lastly, Marcio was cautious to level out to us that there are different underwater photos bigger than a number of gigapixels, however they aren’t panoramas as a result of they weren’t taken from the similar perspective. Moderately, they’re “photograph mosaics” which might be used for different functions reminiscent of underwater mapping and can’t be seen in digital actuality.
