"Head and shoulders above the crowd is The Photographer’s Ephemeris. Odd name, great app." - National Geographic

"One of the most useful apps for any nature photographer" - Outdoor Photographer Magazine

"It worked perfectly. The program was dead on…" - National Geographic

"One of the most powerful photography applications that I've seen, one that you'll be using for years and years." - AdoramaTV

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 visualize exactly how to align your shot.

Research and save your own list of favorite photographic locations, using 7 different map types (including 2 offline maps) and save them in your locations list. Favorite locations are always displayed right 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.

Key features:

- Time/direction of sun, moon, and galactic center rise/set
- View azimuth and altitude of sun/moon and the galactic center for any time of day/night
- Milky Way, stars and asterisms visualization via 3D map overlay
- Moon phase and % illumination
- Civil, nautical and astronomical twilight
- 2 topographic maps
- 2 offline map types
- Movable map pins: drag and drop the pin exactly where you need it
- Map autorotation using the compass (on compatible devices)
- Shadow lengths displayed to scale on map
- Save any location you want: no fixed lists
- Celestial events including moon phases, apogee, perigee, solstice, equinox
- Network connection not required for rise/set time, azimuths and sun/moon position

Advanced features:

- Augmented reality view for on location scouting
- Saved location synchronization between devices and the free TPE web app
- Automatic time zone detection
- Elevation above sea level
- Distance, bearing and elevation angle between any two points
- Location import/export from KML
- Magnetic north option
- Configurable timeline display
- Sun/moon transit times
- 'Golden hour' time/duration
- Light pollution overlay

Geek features:

- Line of sight analysis
- Find when the sun/moon will appear from behind a hill or ridge
- Advanced visual sun and moon search
- Azimuth or altitude search priority
- New crescent moon visibility
- Distance to the visible horizon

Available map types include:

- Standard, Satellite/Hybrid, Terrain
- OpenCycleMap Topographic
- OpenStreetMap

Sunrise/sunset color forecasts are available (covering lower 48, southern Canada and Europe) with a subscription to the Skyfire service, available via in-app purchase.


- Maps and elevation-based calculations require a data connection, except for offline map tiles previously downloaded and stored on your device
- Topographic map data is available only between 60°N and 47°S
- Availability of map types is subject to change, due to 3rd party map service availability, terms or conditions
- The app itself supports only English language at present
- Augmented reality requires an iPhone 6s (or later), iPad Pro or 2017 model and iOS 11 or later

What's New

Version 4.2.1

Some Augmented Reality (AR) enhancements:

- New: map pins now appear in the AR view. This is very handy when trying to relate a position on the map to one in the real world, or when your mountain peak is shrouded in clouds, but you still want to align a shot using AR. The map pins are lit by the simulated sun and moon. They are visible within a 30mile/50km radius of your device. They are scaled up with distance to remain visible on the screen. Pins are only displayed if elevation is known.
- New: on turning live time tracking off, the previous date/time is now restored (so you can toggle time tracking on/off easily to recalibrate to the sun/moon whenever needed without losing your place)
- New : magnetic field out-of-tolerance graphic now moves to side of screen if the condition is persistent (so it's not always in the way)
- Fix: AR layout in landscape on iPhone X has been tidied up
- Fix: AR screen chart respects 12/24 clock setting correctly

- Fixed: rise/set azimuth lines were not hidden during midnight sun (regression bug)
- Fixed: Location notes were not included in KML export
- Fixed: track heading sometimes resets unexpectedly when using Apple Maps
- New style for Google Maps
- Updated SDKs

Hieno softa, ei pelkästään valokuvaajille, vaan muillekin taivaankappaleista kiinnostuneille. Toimii hyvin.

Very good!

A very useful application that is a good complement to the Tilt Calculator app for my photography use! A trusty photographic companion! Recommended!

Absolute top class


What can I say, this is fast becoming my favourite app when planning photoshoots. Extremely useful, plain and simple.
