In the previous photo, Ulloa is taking an “over/under” shot, and this photo is an example of the effect. This shot results from carefully aligning the lens half above and half below the surface. This can be a tricky skill to master, but Ulloa says it’s crucial to look beneath the surface. “The world’s freshwaters are such a small percentage of our planet,” he said. “Our hope and goal is to help educate anybody who is interested in experiencing how special this water is, at least from a visual perspective.”
