The Photographer's Ephemeris

By Crookneck Consulting LLC

The Photographer's Ephemeris (TPE) helps you plan outdoor photography shoots in natural light, particularly landscape and urban scenes. It's a map-centric sun and moon calculator: see how the light will fall on the land, day or night, for any location on earth.

TPE is a universal app with optimized user interfaces for both iPhone and iPads. With version 3.0, we've modernized the user interface to make the most important information easily accessible and easy to comprehend.

TPE's map-based approach means you aren't limited to a predefined list of locations, which often miss the places many photographers go. Instead, search for any place name on the planet or position the map pin exactly where you want it.

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 be visible behind nearby hills and mountains.

- Search your saved locations and the web in situ in the redesigned Locations page
- Sun/moon altitude chart: slide to change time, tap once to adjust minute-by-minute
- Line of sight tools: enable geodetics and use the secondary grey pin to view an elevation profile with visibility analytics; tap to scale; double-tap to cycle through modes (Elevation/Altitude/Sun + Moon); use in conjunction with Visual Search to quickly find a time when the sun or moon will next appear over a mountain or ridge
- Shadow circle: shown automatically when adjusting time of day, it shows when sun/moon are below +6 degrees
- Object height and elevation corrections: new Shadows page allows you to set object heights at both primary and secondary pins as well as elevation corrections. Use this to plan your "moon-behind-a-famous-landmark" shots.
- Visual search: bursting with options to let you find the exact sun or moon alignment you need - check out advanced mode for high precision tools such as disc alignment
- Sharing: share your shot plan via iMessage, Airdrop, Email, Twitter, Facebook etc. Also, open in Photo Transit (iPad only), Email a complete shot plan, Add to Calendar, Export Locations

Sadly past its best!

I used to use this App a lot for my professional photography. The user interface was simple and intuitive with option to store locations - a feature I used heaps. Similarly with my desktop Mac App.
Sadly these features have all been lost, with the demise of the Desktop App, becoming web based with "yet another" website to login to if you wish to save locations. The iPad App UI is now cluttered and all my saved locations gone without so much as a mention!
Well done coders for jumping on the bandwagon with too many bells and whistles and fixing the unbroken. This is still a very useful tool and fantastic for free but let's make it perfect once more - please, and no signing in to an account, I live in rural Devon with next to no mobile signal so forget me logging in on the go!! Looking forward to the new upgrades. :)


The missing link in my photography! I never can work out which way the sun is moving or where to go. A great aid to my photography was just serendipity before. Added bonus I can work out where to park my car so it ends up in the shade! A very useful and for my needs at least very easy to use.


Astounding app. You can view a plethora information, each item an eye opener. Indeed, it's so packed with eye-grabbing info it's a joy just to browse through it all. That said, it is what it sets out to do - provide an ephemera of essential tools for helping you get the best out of your photography, no matter whether a beginner or pro. Great.
