The Photographer's Ephemeris (TPE) helps plan outdoor photography shoots in natural light, particularly landscape and urban scenes. It's a map-centric Sun, Moon and Milky Way calculator: see how the light will fall on the land, day or night, for any location on earth.
Whether you need at-a-glance information on today's sun, moon and Milky Way data for your current location, or need to plan a precise alignment of the full moon for a future shoot, TPE has the tools you need. The combination of augmented reality, line-of-sight analysis and visual search supports the most sophisticated photo planning needs.
Night mode features a 3D representation of the Milky Way, pole stars and major constellations directly over the map, so you can easily visualize exactly how to align your shot.
Research and save your own list of favorite photographic locations, using 7 different map types (including 2 offline maps) and save them in your locations list. Favorite locations are always displayed right on the map.
Advanced features including visual sun and moon search, automatic time zone and elevation detection, correction for atmospheric refraction and height above the horizon, ensuring that you have the best possible information for planning your shoot.
You can even determine when the sun or moon will rise from behind nearby hills and mountains.

What3words: we're delighted to add support for what3words. what3words provides a unique three word address for any location on earth. Find out more at what3words.com.
We've refreshed the Locations page to make it simpler to navigate. Saved locations now have their own dedicated page - you can filter your locations by name and favorites, as before.
Search is broken out into two new screens. Type address or place name into the Address/Place search field and TPE will suggest matches as you type. You can enter a three word address too!
When you open the Coordinates Search page, TPE automatically shows the red map pin position (or grey if geodetics is enabled). You can type or paste in any latitude/longitude coordinate into the field and we'll convert it to a usable location you can save. We automatically display nearby places and the corresponding three word address. You can add these directly to your saved locations list, or use them to set the map pins.
Please send your feedback and suggestions to email@example.com - we'd love to hear from you.
If you're enjoying TPE, a review on the App Store is really helpful and lets us keep improving the app.

For City/Landscape Photographs
It is great to show you the elevation and “Flow” of the land. Also it has 4 types of maps showing this in Google & 2 using Apple maps. You can see what you are getting into, but you must remember the this is just a map form yesterday, new trails or changes are not shown. Also the view is of the elevation is great as long as they haven’t built anything or grasses/trees grown too much, which is not true for Charlotte,NC. All this being said, I related the program a 5 Star because it shows you so many points of view, the sun & moon flow in the sky at a specific time and a better location to at least start looking for a good spot to get the frame you want. This program is great for starting a plan from your house and then going out for the picture.
Nothing else like it!
Extremely useful app, if you want to plan your photography for a trip or event. Pick your location-instantly you see sun and moon rise and set times. Tap on the date to pick a future date. Swipe a finger across the display at the bottom to see the direction of sun or moon overlaid on the map-satellite photo help plan the shot, and even tells you if terrain will obstruct your view of eg sunset. I have used it to choose location for a one time trip to the Mackinaw Bridge, as well as look to see where is the closest place to travel for the next solar eclipse.
If you care about getting the most good locations for your photo trip, hands down this is the one to get!
I’ve been using this app for about a year or more and it has proven very useful. I have several locations saved near home and a National Park where I go to to observe and photograph sun and moon rises and sets.
Particularly, I try to photograph moon rises or sets within the Earth’s Shadow. This app provides the times and locations where this will happen. What it cannot do is control the weather, so ultimately it is still a challenge, but using this app ensures that you have all the information at hand to be in the right place at the right time.
