TPE for Desktop

About TPE for Desktop

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 for Desktop is the original – and free – version of the program, and is the premier outdoor photography planning tool used by thousands of photographers, amateur and professional, around the world.

With the new web app, TPE has evolved from its original form, but the core purpose remains the same: to provide an elegant, visual way to plan the natural light of the sun and the moon for your outdoor photography.

Getting Started

You can start using the new TPE for Desktop web app in your browser immediately.

What is a web app?

A web app is a software application that runs in your web browser.

There is nothing to download or install – you simply open the web app in your browser, as you would with any other web page.

1) Pre-requisites

You’ll need a current version web browser.

We’ve tested in

  • Safari 7.0.5, 7.0.6
  • Firefox 30.0, 31.0, 32.01
  • Chrome 36.0.1985.125, 37.0.2062.122
  • Internet Explorer 11
  • Opera 22.0

If you’re stuck with an older version of Internet Explorer or Safari, you’ll need to install an alternative, such as Chrome, to use the TPE web app.

Note: if you have your browser configured to block cookies or local storage, the app won’t work properly. Also, ad-blocking, privacy and identity protection add-ons may cause the app to mis-behave, particularly if they block calls to third party sites such as Google Maps.

2) Download the Quick Start Guide

The Quick Start Guide is a free 2-page PDF that gives you an overview of all the key functionality of TPE, plus a reference to the many keyboard shortcuts that are available. If you want to become a TPE power user, we’d recommend familiarizing yourself with the shortcuts!
