# The Photographer's Ephemeris

## TPE for Android is here!

We're pleased to announce that TPE for Android is released! As any of you who've been following along will know, it's been something of a marathon, but finally it's out the door. The initial release is optimized for Android phones. We've made some adjustments to the GUI as we've developed this version and we think this is the easiest to use version to date. With full support for all functionality in both portrait and landscape modes, we hope you enjoy it!

### Beyond Android

Now that TPE for Android is out, we have some exciting updates planned for TPE for Desktop and TPE for iOS. More details to follow...

## Books and eBooks

Back in July we were delighted to release an eBook Understanding Light, co-written with renowned landscape photographer Bruce Percy. The book explores how to improve your photography through an understanding of natural light using TPE as a tool to plan and execute your shots.

Bruce has just announced his first printed book, The Art of Adventure which will be released on November 11 2011. The book includes 40 examples of Bruce's best work, including some of the images discussed in Understanding Light. You can pre-order it now!

## TPE 2.0 for iOS Released!

TPE has come to the iPad, and is feeling much relieved for the larger screen real estate! We're happy to have been able to take advantage of the iPad's higher screen resolution to provide a much expanded map view and the ability to see all the key details in one place. Rotate to landscape, and once again you can browse the sun and moon times across a week, just as with TPE for Desktop.

We've renamed TPE for iPhone to TPE for iOS to reflect its multi-device support, and bumped the version number up to 2.0. The iPad UI now includes a visual indication of sun and moon altitude, overlaid on the map. And, in response to popular demand, location coordinates are now directly editable (on iPad - we'll carry this through to other platforms soon).

We'd love to know what you think of TPE on the iPad. If you have any comments, or if you have any technical issues or questions, please e-mail support@photoephemeris.com. Alternatively, you can reach us on Twitter via @photoEphemeris.

TPE for Desktop, as always, remains available free of charge - see the download links to the right.

## What's it about?

The Photographer's Ephemeris (TPE) is a tool to help with the planning of all types of outdoor photography, but particularly landscape and urban scenes.

It is a map-centric sun and moon calculator: see how the light will fall on the land.

TPE's map-based approach means you are not limited to a predefined list of locations, which often don't include 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 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.

Key features of TPE for iOS:

- Time and direction of sunrise and sunset
- Time and direction of moonrise and moonset
- Phase of the moon and % illumination
- Times of civil, nautical and astronomical twilight
- Graphical display on a map
- Save any location you want - no fixed lists
- Automatic time zone detection for any location on earth
- Determines elevation above sea level
- View azimuth and altitude of sun/moon for any time of day/night
- Distance, bearing and elevation angle between any two points
- Find when the sun/moon will appear from behind a hill
- Compensation for atmospheric refraction
- Compensation for elevation above the horizon
- Does not require network connection for rise/set times and azimuths. (Note: maps and elevation do require a data connection)

Welcome to the new home for The Photographer's Ephemeris (TPE). With the forthcoming addition of an iPhone App it was high time to give TPE its own dedicated site, so here it is. Please bear with me while I put this together over the next few days.

Once complete, all the material from http://stephentrainor.com/tools will migrate over here and we should have room for plenty of additions too.
