When Cristina Mittermeier once searched the term “conservation photography” all she found was info about how to preserve photos for museum display. Today, she and her partner Paul Nicklen are some of the most recognizable names in the field and are regular contributors to National Geographic - the magazine and Instagram feed. Together, they’ve amassed a social media following like few other photographers out there. They co-founded the organization SeaLegacy, whose mission is to create healthy and abundant oceans and they’re using their photographic prowess to tell critical stories about ocean life.
