May photograph by Hayden Smith, Airtight Aerials

Hitting the heights of aerial photography

It seemed like a natural progression for Hayden Smith to take his photography business Airtight Aerials to the next level with drone technology. 'I loved photography and really enjoyed flying drones, so I thought, why not combine the two?', he says. Hayden has also managed to bring together aerial photography with his other passion—surfing—which is how he came to be at Pyramid Rock in Phillip Island, Victoria, just before sunrise that morning. The plan was to fly the drone until sunrise and then go for a surf, but he says before he knew it a thick cloud of fog came out of nowhere, totally engulfing him. Hayden says he'd never seen anything like it before and couldn't even see two metres ahead of himself. But, from above, the drone captured something magical—and it's these unique perspectives that continue to drive Hayden to new heights.

The science

Sea fog, as shown this photo, is formed when warm and moist air passes over a cooler body of water. As the air passes over the surface of the water, it cools, and water vapour in the air condenses to form fog. Breaking waves on the beach release salt particles into the air, which help to form the fog. This kind of fog can be 'advected', or pushed, over land by the wind.
