Focus Collection is a series of wallpapers for your desktops and homes screens that make good use of minimalistic textures. Each one is crafted from scratch in Photoshop: taking a beautiful photograph and applying a heavy gaussian blur and some noise to present a frosted glass texture. Easy on the eyes. Good for your concentration.
