"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 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.

- Changed the default style of offline topographic map from OpenCycleMap to Thunderforest Outdoors (better peak name display)
- Link to new service status page in Help
- UI fixes and refinements
- Updated SDKs and libraries
This version uses Skyfire v3 for North America forecasts. The v3 platform has been built from the ground up to run on a new cloud architecture. One of the primary benefits of the new platform is that multiple forecasts can be generated in parallel. This has allowed us to increase the update frequency significantly. The current schedule for North America forecast updates on the new platform is:
Today: hourly refresh
Today +1: sunrise - hourly, sunset - every 2 hours
Today +2: sunrise - every 2 hours, sunset - every 4 hours
Today +3: every 6 hours
Today +4: every 8 hours
Generally, you will see the updated forecast become available at twenty past the hour. Schedules start from midnight UTC, hence, so, for example, 4-hourly updates will be available at 00:20, 04:20, 08:20 etc. We expect to move EU forecasts to the v3 platform also in the coming weeks.
Ratings and Reviews
Superb tool for photographers/astronomers/dronepilots etc
If you want to know how a location that you’ve yet to visit will “look” at different times of the day or night, then this is the app for you. When will the daylight produce the shadows your looking for to make your image “pop”? What time will a particular constellation be seen over your chosen object? This app has the answers! Worth every penny of the cost.
If you’ve a query, the developer is super fast to respond too! 10/10!
A wise choice!
It's pretty simple, really; we think that we know where it rises and sets, but in reality we're mostly clueless as to the movements of the sun in relation to our surrounds. There's little worse than promising yourself or a third party that you have the best place from which to capture the sun, shadows, twilight, etc... only to find that you were miles out. This App fixes that problem. Simple. Brilliant. Easy to follow. Download it now!!
Now I can believe the 5 star reviews
Update to my previous review.
Response from support was great, and they pointed out why I seemed to be getting inaccurate sunrise and sunset times on a particular location. Essentially, I had somehow set an incorrect local time for one of my saved locations (my bad!).
This is a complex app, and it clearly takes some time and effort to use, but very useful once you get to grips with it.
Developer Response ,
John - as per my reply to your support email, the issue is that the saved location has the incorrect time zone (GMT+06:00).
The fix is simply to refresh the time zone for the saved location or delete it and save it afresh. It's possible the incorrect time zone could have occurred if you saved the location when your phone had no internet connection.
