Plan your light, simply

The Photographer’s Ephemeris (TPE) for Android helps you plan outdoor photography shoots.

TPE is a map-centric sun and moon calculator: see how the light will fall on the land, be it day or night, for almost anywhere on earth.

Ideal for landscape, nature, travel and outdoor photographers, TPE’s map-based approach means you can search for any place name on the planet or position the map pin exactly where you want it.


A simpler Experience

TPE for Android offers a simpler user experience than our more advanced apps, focussing on the key things you need to know for effective shot planning: the direction and timing of the sun and moon.
