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.

TPE's map-based approach means you aren't limited to a predefined list of locations, which often miss the places many photographers go. Instead, search for any place name on the planet or position the map pin exactly where you want it.
Advanced features including visual sun and moon search, automatic time zone and elevation detection, correction for atmospheric refraction and height above the horizon, ensuring that you have the best possible information for planning your shoot.
You can even determine when the sun or moon will be visible behind nearby hills and mountains.
- Time and direction of sunrise, sunset, moonrise and moonset
- Phase of the moon and % illumination
- Times of civil, nautical and astronomical twilight
