What is it about carnivals that makes them such an endless source of interesting subject matter? Photographer Brian Carlson began working on his carnival series ten years ago and says, “The beautiful thing about pursuing a photo project over the long haul is you really hone in on what and why you’re taking photos…Out of all my work, whether it be portraits or lifestyle, the photos in this series are some of my all-time favs.” It’s paid off this year with the image above selected for inclusion in the AI-AP American Photography 38 book.
