The original PolkaDot Perch

Curious how we came up with PolkaDot Perch? It started with one of the first underwater images Greg ever captured. Not his very first. His first underwater shot was a wash-out still-life of his feet and a beer can taken in a friend’s backyard pool when he was still a wet-behind-the-ears teen.

Even when oceans, lakes, or rivers look crystal clear the water is filled with microscopic bits of life. The majority of these particles are too tiny for us to see but they are super reflective. When hit with bright lights, the particles show up (and usually ruin) underwater photographs. Underwater shooters refer to this phenomenon as “backscatter.”

The ability to properly light the image without creating any backscatter is one of the marks of professional underwater shooters.

On the road to becoming a pro, Greg took his share of throwaway shots. One near-great shot of a yellow perch was ruined by backscatter. But, rather than throwing the shot away, Greg jokingly labeled and filed it as the highly elusive “Polka Dot Perch.”

It’s the elusive PolkaDot Perch!!
