At C2G2 Productions, we bring a sense of calm and ease—and fun—to our filming, photography and publishing projects. It doesn’t matter if we’re filming giant manta rays on a reef or little green ants on a tree branch. Our sense of wonder—and our commitment to getting the shot and the story—is the same. Our motto is, “Make it fun. Let it be easy.”

We believe in treading lightly on this earth, and strive to leave a place better than we found it. A portion of our production income is dedicated to protecting threatened marine species, preserving indigenous cultures and providing medical care and clean drinking water for all.
