The Photographer’s Ephemeris (TPE) helps you plan outdoor photography shoots in natural light, particularly landscape and urban scenes. It’s a map-centric sun and moon calculator: see how the light will fall on the land, day or night, for any location on earth.
TPE is a universal app with optimized user interfaces for both iPad and iPhone/iPod Touch devices.
“Head and shoulders above the crowd is The Photographer’s Ephemeris. Odd name, great app.”
