There are a few Adobe Air products that I have been playing with recently. I think that we tend to dismiss the value of these little apps - and probably for many of us we have never really heard of Adobe Air, or looked into the products.
The Adobe Air applications install very easily on your computer, and many seem pretty easy to use. Simple functionality appears to the be the design purpose behind them - plus some nice looking and slick GUIs (graphical user interface) in many cases .
This particular Air application called "The Photographer's Ephemeris" may prove extremely valuable to some photographers. While it's main design objective appears to be Landscape Photographers who need to plan their shoots around the times of sunrise/sunset or twilight, or alternatively when the moon is in a particular place in a particular phase - - - I think that this data can be very valuable for any photographer who wants to know when the sun is rising or setting, so as to know when to schedule shoots (a lot of my outdoor shoots are early in the morning or late in the evening). Particularly do I find this type of chart valuable, when I am booking dates into the next year or two and have different times not considered the restricted daylight and changes sunset/sunrise times in say late fall.
One thing I found of great value, was the integration with Google maps - making it possible to drag the coordinates around to very precise locations around the world, or in your shooting area - - - and watch the data change and reflect the changes that would be in place for those areas.
The App can be downloaded from the Adobe website -
