"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

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

- Augmented reality requires an iPhone 6s (or later), iPad Pro or 2017 model and iOS 11 or later

Kaz Balinski ,

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!!

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!

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.
