Seth Casteel's new book Underwater Dogs has been turning a lot of heads lately. Petapixel recently did an investigation on his creative process, and they learned that it's not as easy as we'd like to think. He uses a camera and overhead flash, all waterproof, capturing dogs that appear shark-like after a lot of trial and error. It's no wonder that his images have become super viral this year, and we hope it inspires people to pick up the book, too.
