About TPE: The Photographer’s Ephemeris

TPE - The Photographer’s Ephemeris® has been helping professional and hobby photographers plan and execute great shots in natural light since 2009. Available for both desktop and mobile devices, TPE provides a toolset aimed at any photographer working with natural light. Beyond our core constituency of landscape and architectural photographers, TPE is used by videographers, cinematographers, archeologists, archictectural design firms, accident investigators, law enforcement, and more.

History

TPE was conceived in 2008 following a landscape photography course in Rocky Mountain National Park, Colorado. After a classroom session that required use of paper-based topographic maps, protractor, calculator, pencil and ruler, it felt like the time had come for a digital tool built using online maps.

The original ‘TPE for Desktop’ was released as a beta in March 2009 and quickly found a following online. An iPhone app was released in April 2010 and enhanced to support iPad later that year. TPE for Android was first released in November 2011.

In 2014, on the retirement of Google Maps for Flash, the original TPE for Desktop was replaced by a browser-based web app. This was rebuilt again in 2020 and is available here.

Our iOS app has been enhanced significantly over the years to include augmented reality, 3D map overlays, location synchronization, night mode (Milky Way, stars, asterisms), and more. We also expanded our portfolio, adding The Photographer’s Ephemeris 3D, the ultimate tool for mountain landscape photography planning and visualization.

Since its original release, TPE and its sister app have been used by hundreds of thousands of photographers, both amateur and professional, in over 220 countries around the world to plan some of the most distinctive photographs of our times.

Our Company

Crookneck Consulting LLC, doing business as Photo Ephemeris, was founded by Stephen Trainor and Alison Craig.

Originally from the UK and Australia, we took up landscape photography after moving to Boulder, Colorado in 2007. As keen scuba divers, the plan had been to do underwater photography. Instead, finding ourselves in the beauty of the American Southwest, landscape photography proved the perfect way to explore the region.

We don’t really do any consulting nowadays, but instead work on TPE!
