  • Cristina Mittermeier

    National Geographic Photographer
    Photographer Cristina Mittermeier dedicates her life to creating images that help us understand the urgent need to protect wild places. Born in Mexico, Cristina first discovered her insatiable passion for the natural world, both above and below the surface, as a marine biologist working in the Gulf of California and Yucátan Peninsula. From there, it didn’t take long for her to realize that she could make a bigger impact on how people see the world, and connect to it, through the lens of her camera than through data on spreadsheets. Specializing in conservation issues surrounding the ocean and indigenous cultures, Mittermeier has worked in more than 100 countries on every continent in the world.
