For landscape photography, it’s good to always be aware of the sunrise/sunset times, and the sun’s azimuth at these times. It helps to know this for the moon too (as well as the current phase). Lots of information to keep track of, huh?
Here’s a quick look at some of this tool’s great features:
- Calculates sunrise/sunset times and azimuth for a particular day
- Calculates moonrise/moonset times and azimuth
- Overlays the sun/moon azimuth onto a Google map
- Change time of day and watch sun/moon position change on the Google map
- Also calculates civil, nautical, and astronomical twilight times
- Quickly jump to any date in the past or future
- Save a list of frequent locations
Previously, I would use Stellarium (also a free program) to accomplish some of these same things, but The Photographer’s Ephemeris is great because it’s made for photographers, whereas Stellarium is really made for astronomers.
What really makes this program unique is it’s integration with Google Maps, allowing you to visualize the sun/moon positions on top of a topographical map.
This program can be great for showing you where the sun or moon will rise/set in relation to certain geological features. It will help answer that question, “is that mountain gonna block the sun from shining on my subject at sunset?”
The Photographer’s Ephemeris can easily become one of your best scouting and planning tools.
