In “The High Concept Image,” a recent feature in Outdoor Photographer, nature photographer Ian Plant intelligently challenges photographers to capture creative, thoughtful images that move beyond “snapshots,” rising to the level of “art.”

Ian’s description of the high concept image is in contradistinction to the “low-concept image,” which he points out is generally more “documentary” or “literal” in nature. Seeing nothing wrong with such grab shots, he does, however, push photographers to look for new ways to depict the world.
