The Photographer's Ephemeris (TPE) helps plan outdoor photography shoots in natural light, particularly landscape and urban scenes. It's a map-centric Sun, Moon and Milky Way calculator: see how the light will fall on the land, day or night, for any location on earth.
Whether you need at-a-glance information on today's sun, moon and Milky Way data for your current location, or need to plan a precise alignment of the full moon for a future shoot, TPE has the tools you need. The combination of augmented reality, line-of-sight analysis and visual search supports the most sophisticated photo planning needs.
Night mode features a 3D representation of the Milky Way, pole stars and major constellations directly over the map, so you can easily visualise exactly how to align your shot.
Research and save your own list of favourite photographic locations, using seven different map types (including two offline maps) and save them in your locations list. Favourite locations are always displayed right there on the map.
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 rise from behind nearby hills and mountains.
