The Photographer’s Ephemeris

Posted by Gary Ramey on November 3rd, 2011

The Photographer’s Ephemeris is an application that will let you know when the sun and moon rise and set plus a lot more than you might expect. Here is a list of key features:

  • 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)

Being able to see the direction that the sun and moon will rise and set is extremely helpful. Rather than scanning the horizon, you know in advance where to look. It is also helpful that The Photographer’s Ephemeris takes into account your elevation. The higher you are, the sooner you will see the sun and moon rise and the longer they will be visible when they set. Being able to save locations is another feature that I appreciate.

The desktop application of The Photographer’s Ephemeris is free. The iPhone, iPad, iPod Touch version is $8.99 via iTunes and the Android version is $4.99 through the Android Market. I don’t know why they have such a price difference between the iOS and Android versions. I have an iPhone and iPad so ponied up the $8.99 and am glad I did. It runs well and solves some frustrations when I am trying to shoot the moon and sun. I can now plan way ahead and predict exactly where the sun and moon will be on the horizon. If you only occationally need information about the sun and moon, you can stick with PhotoBuddy on the iPhone, iPad, or iPod Touch and just download the free version of The Photographer’s Ephemeris.
