About this app

The Photographer's Ephemeris (TPE) helps to 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. Our Android app provides all the basic functionality you need to plan sun and moon photography.

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.

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.

Five map types are offered, including two topographic maps, ideal for landscape and nature photographers. Open Street Map and Open Cycle Map Topographic offer automatic offline support: any tiles you view are automatically cached for offline use.

Key features:

- Time and direction of sunrise and sunset
- Time and direction of moonrise and moonset
- Phase of the moon and % illumination
- Times of civil, nautical and astronomical twilight
- Graphical display on a map (Standard, Satellite/Hybrid, Terrain, Open Street Map, Open Cycle Map Topographic)
- Rotate and tilt the map for the optimal view
- Compass-based auto-rotation of the map
- Movable map pins - drag and drop the pin exactly where you need it
- Search for locations by address, place name, or enter coordinates directly
- Save any location you want - no fixed lists
- All features available in both portrait and landscape mode

Note:
- This app has a limited feature set relative to its iOS equivalent: please review this listing carefully to ensure that the features you need are included prior to purchasing
- Maps and elevation-based calculations require a data connection to function (execpt for Open Street Map and Open Cycle Map Topographic, which are cached to your device automatically)
- Locations outside ±80° latitude (very far north and south) are unsupported
- Map auto-rotate requires a compatible device (with magnetometer and accelerometer)
- Requires that you have Google Play Services and Google Maps installed on your device. Most devices already have both installed. TPE will prompt you to install these if they are missing.
