As photographers, we all talk about the “golden hour”–that brief period of time at sunrise and sunset in which the lighting is just perfect. But what time is sunrise anyway? Or sunset for that matter? Better yet, what time will the sun set this time next month when you have the big beach wedding to shoot? What time will the sun rise in Las Vegas in mid-May? What phase will the moon be in when you are shooting that night senior portrait shoot in Asheville, NC? Okay, the truth is that I don’t know the answer to any of these questions. But I know an app that does.
VelaClock Sun/Moon app from Vela Design Group will answer each of these questions and more. Here is the gist of it. When you first open the app it will ask to use your current location. Once you do that you can use your current location or add other locations. Once you select your location, you can view a great deal of information about it. For instance, you can see when the sun will rise and set. The app will give you the astronomical twilight dawn and dusk, nautical twilight dawn and dusk, and civil twilight dawn and dusk.
Okay, I admit that I didn’t know what these terms mean, so I’m guessing that perhaps someone else might need a little refresher. Astronomical twilight occurs when the center of the sun is 12° and 18° below the horizon. If you are looking for darkness, you will find it from the end of the astronomical twilight in the evening to the beginning of the astronomical twilight in the morning (barring light pollution). Nautical twilight refers to the time when navigation at sea using the horizon is not possible. This occurs when the center of the sun is between 6° and 12° below the horizon. Civil twilight in the morning begins when the center of the sun is 6° below the horizon and ends at sunrise. Likewise, civil twilight in the evening begins at sunset and ends when the sun is 6° below the horizon. This is the time when you can best view the brightest stars and planets. Read More→
