"Though Ms. Gao commands more awe than most, every day countless Instagrammers are busy showcasing their sensibilities by shooting their own still lifes—arrangements they've stumbled upon or, more likely, contrived. They cram cream tulips into green glass bottles to say, "I'm drawn to quiet colors." They line up fossils and postcards of Edward Hopper paintings on mantels to convey, "I like musty, natural beauty and have a lovable streak of melancholy." These photos, portraits of one's taste, are a twist on selfies, hopeful bids for attention in which one's aesthetic and one's ego overlap. Given that the objects are often arrayed on a shelf or the equivalent (a windowsill, a desk), you might even call the images "#shelfies." Some Instagrammers already do, though more typically when they've snapped bookcases."
