"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

We've refreshed the Locations page to make it simpler to navigate. Saved locations now have their own dedicated page - you can filter your locations by name and favorites, as before.

Search is broken out into two new screens. Type address or place name into the Address/Place search field and TPE will suggest matches as you type. You can enter a three word address too!

When you open the Coordinates Search page, TPE automatically shows the red map pin position (or grey if geodetics is enabled). You can type or paste in any latitude/longitude coordinate into the field and we'll convert it to a usable location you can save. We automatically display nearby places and the corresponding three word address. You can add these directly to your saved locations list, or use them to set the map pins.

Please send your feedback and suggestions to - we'd love to hear from you.

If you're enjoying TPE, a review on the App Store is really helpful and lets us keep improving the app.

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!

Amazing tool

I had this app for a while but never really investigated it thoroughly as I initially found it a bit daunting. Finally with an impending lunar eclipse that was looking to be visible in my part of the world and clear skies as well I clicked on help!

But with a small investment of your time, particularly watching the video tutorials, you will be amazed by how useful this app can be. Not only photographers but anyone who enjoys nature and wants to plan the perfect moment.

Thanks Adam - glad you're enjoying the app, and that the video tutorials were useful!

Simply Amazing

There is so much to this app. Beautifully designed and really meticulously thought through with myriad functionalities. Was a bit daunted when I first opened it up, but the video tutorials soon resolved that. I’ve only begun to scratch the surface, but am already aware that this is an indispensable time saving tool for photographers, DOPs, location scouts and more.
