Today Instagram Stories adds a more subtle and mature but error-prone copycat of Snapchat’s beloved augmented reality selfie filters. The eight initial “face filters,” as Instagram calls them, work exactly like Snapchat, and let you add virtual koala ears, nerd glasses, a butterfly crown or wrinkle-smooth makeup to yourself and friends in photos or videos.
Instagram, like their parent company Facebook, have the whole “just copy your competitor’s idea” thing down to a science at this point.
