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.

“The Photographer’s Ephemeris is an unbelievably feature-filled and impressive App available for iPhone and Android…which, among many other things, delivers super-accurate and helpful information related to the sun and the moon”

TPE for Android is available for phones running Android 2.2+. (It runs on tablets too – see notes below.)

Advanced features include: automatic time zone and elevation detection, correction for atmospheric refraction and height above the horizon. You can even determine when the sun or moon will be visible from behind nearby hills and mountains.

  • Maps and elevation-based calculations require a data connection to function

IMPORTANT: if your device has the old Android Market app instead of Google Play, you may be unable to install Google Play Services if it is missing. Please visit for further details.
