This spring hth® was lucky enough to have renowned underwater photographer Seth Casteel shoot our new online marketing campaign. Seth is the creator of the best-selling book Underwater Dogs. He followed that up with Underwater Puppies and Underwater Babies.

Here are a few of the images Seth took for hth®.


Watching Seth work was fascinating, and it got us thinking: This is something other pool owners should try. We hope Seth’s story inspires you this summer.

Q&A with Seth:

Q: Where did you learn photography?

I am self-taught.

Q: How did Underwater Dogs come about?

I was photographing a Cavalier King Charles Spaniel named Buster back in 2010 in his backyard in California. The photo shoot was meant to be “on land,” but Buster decided he would rather be in the pool.

As I watched him dive in over and over again chasing his favorite mini tennis ball, I thought, “What does he look like under there!!” I left, bought a little point-and-shoot underwater camera, zipped back and jumped in. The resulting photos were the beginning of the series of underwater dogs.

Q: Is it true that you spent the last $ on your credit card to buy an underwater camera housing?

The point-and-shoot camera was a good start, but I needed improved gear to fully pursue this project, so I spent the last available credit I had on my credit card to buy an underwater housing designed for surf photographers. My friends told me, “Why are you doing that! You should photograph weddings!” I said, “I am not a wedding photographer. I am a dog photographer.” Months later, to my surprise, the series of images I created with the housing became a viral sensation on the Internet, resulting in a book deal with Little, Brown and Company, opportunities with National Geographic and The New York Times, international art exhibitions and the launch of

Underwater photography tips for beginners.

  • Practice your dive skills first. The longer you can stay under, the better results you’ll have.
  • Shoot close to your subject. Underwater, you’re not as close as you think.
  • Try shooting upward. Having the subject above you adds drama.
  • Use the flash, and work on balancing it with the ambient light to make your shots more dramatic.
  • Fire away. Take advantage of the instant gratification of digital photography and shoot lots of pictures. Practice, experiment and have fun.
