This photo is from a photowalk along the reed path at Lake Neusiedel. I wanted to get some good shots during the sun set. Using the Sun Surveyor App [iTunes App Store Link] I could exactly plan my shooting. After I selected a location on the map, Sun Surveyor told me the exact time frame of the Golden and Blue Hours before and after sunrise or sunset.
But the app tells you even more than that: It tells you the height of the sun or the moon above the horizon and where they will rise and set. It even tells you the direction of the shadows during daytime.
Sun Surveyor has earned a top spot on my iPhone and I use it regularly to plan my photowalks. It’s an app that should be on smartphones of every photographer.
