This week: A photographer shines light on Mexico’s Indigenous people. Plus, the historic D-Day photo that was almost lost to history, and what is it called when animals glow- in-the-dark?

PHOTOGRAPH BY YAEL MARTÍNEZ

Photographer Yael Martínez, a National Geographic explorer, has embarked on a project to illuminate the lives of Mexico’s Indigenous people—literally. By using a technique he calls “interventions,” Martínez makes pinpricks in printed photos, shines light through the holes, and rephotographs them to create a luminous, tactile image.
