"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

"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 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.

Key features:

- Time/direction of sun, moon, and galactic centre rise/set
- View azimuth and altitude of sun/moon and the galactic centre for any time of day/night
- Milky Way, stars and asterisms visualisation 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 synchronisation 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
- Availability of map types is subject to change, due to 3rd party map service availability, terms or conditions
- Augmented reality requires an iPhone 6s (or later), iPad Pro or 2017 model and iOS 11 or later

Great App!

Ian Carson

I use TPE and her sister programs to plan every large landscape shot I take. It’s fantastic for choosing the right spot and the right time of year to get exactly the shot envisaged by the photographer. It’s also great for exploring shot concepts when time is limited and landing on those with the greatest chance of success.

The time period indicators such as “Golden Hour” allows me to plan out leaving times from base camp and ensures I always have sufficient time to setup my shots ( I take a lot of HDR multi-position landscapes)

I have just recently started Astrophotography and now also use TPE 3D in conjunction with this app for planning.

Keep up the great work guys. Looking forward to seeing “Skyfire” for Australia and NewZealand!

Import and export of locations

Eat My Flamin Hat

Why is it so difficult to import and export locations? Why do I have to “email” them to do this? Wouldn’t it be much easier if I could save the KML file to “Files”???

This handicap really spoils my enjoyment of TPE, I’m sorry to say!!

Developer Response

This seems like a niche situation. ~99% of users never need this function at all, and of the ~1% who do use it, it's an occasional thing. The mechanism for importing locations is the same as every other app that opens KML or KMZ files.

I like the idea of switching to use Files (particularly for export), but that's available on iOS 11 only and we still currently support iOS 10.

The right time and place, every time!


Ansel Adams is quoted as saying "A good photograph is knowing where to stand." With TPE I can get a very good idea of where and when I want to stand, and what I'll be able to see. I've been using the app for quite a while, and the latest version adds even more information on elevation and the visibility of astronomical bodies. In my opinion it is essential for landscape photography, and very easy to use. The ability to synchronize my locations between iPad and iPhone just improves the convenience even more. I recently had a technical problem with the app, which Stephen went to quite a bit of trouble to fix. Well done, for a great app and excellent service. If you're a photographer get TPE!
