Last week in Lake Eva, Alaska, Naturalist/Certified Photo Instructor Eric Guth spent an afternoon experimenting with shooting plants under ultraviolet light to mimic what the plants might look like to pollinating insects. In his words: “We all have our perceptions of the world, so sometimes it’s fun to think outside the bounds of what we see and know and try to imagine the world as others might perceive it, whether that someone be vertebrate or invertebrate. Human or otherwise.” Get Inspired By Photos, Videos, Webinars, Stories, And Exclusive Offers. Sign Up

Many of this week's photos from the field experiment with seeing the landscape and wildlife in new ways, from a polar bear mid-meal in Svalbard as seen through an iphone and telescope, to the bow of  National Geographic Venture  reflected in still Alaskan water, to a Galápagos flamingo in a brackish lagoon framed by local vegetation.
