We’ve all seen those tourists who lose all common sense when they spot a wild animal, getting way too close just for a selfie. This filter helps avoid those dangerous situations by showing you if you’re too close to the animal—just download it, point your phone at the animal, and the filter will let you know if you need to back up. It’s especially handy in places like Jackson, Yellowstone, and other wild areas where people often forget that these aren’t pets.

The filter comes with safe viewing distances preloaded for animals like bears, bison, and moose, and the Tourism Board hopes it’ll help reduce the number of close-call incidents while still letting you get that perfect shot. Plus, they’ve made it open-source so anyone can update it for the wildlife in their area. So, next time you’re out in nature, use the Selfie Control filter to stay safe and give the animals the space they need.
