I use LightTrac for the iPad. Not only does it tell you when but also the angle from which the sun will be coming at sunrise, sunset and right now, as the sun position varys seasonally. Besides, it's cool to be able to drag the slider around and see how the direction of the sun rays will vary. So say I want to photograph the tower in the middle of the plaza ...

You're right. The atmosphere has a prismatic effect, spreading white light out into its constituent colors. As the sun moves down to the horizon, you the viewer move into the orange-red band of light. The lower the sun can get, the more red the light will be. The atmosphere is also a diffuser. The more of it there is between you and the light source, the ...

There are a number of techniques employed to get the look of the examples you posted. I think you're correct about the lighting, these pictures were taken with the optimal lighting for their location. The contrast was enhanced. This might be an automatic process as suggested by che, or it may be done by selecting areas of the image and enhancing the ...

Yes, it's mostly post-processing. The images have very high contrast, which also makes the colors more vivid. You can also increase the saturation to get more vivid colors without getting too high contrast. Your reflection on the lighting is probably correct; the images should have reasonably high contrast and color to start with, or they will look too ...

Iceland is so far north that depending where you are in the country, you get significantly different results. Compare the following chart from gaisma.com for Reykjavík, which is in the south: With this chart, for Ísafjörður in the north: As you can see, between mid June and the beginning of July, the sun never actually sets in the north of Iceland, ...

On Android there's a great app called Sun Surveyor. This will tell you sunrise/set/golden/blue times, as others do. But it's got the map view (as shown elsewhere), and another unique feature, which is an "augmented reality" view where you hold your phone up, and it uses the camera to overlay on the real scenery the path that the sun is going to take during ...

You can get close to this kind of look by enhancing local contrast. This works a bit similar to HDR tone mapping, and can be archieved by using unsharp mask filters with high blur radius. This example was a bit overdone so you can see how easily this can go wrong. Usually you'll get nicer looking results by using just a small amount of this, and perhaps ...

I use an app called 'PhotoCalc' - it does sunrise and sunset (though not currently moonrise and moonset) based on your position on GPS, and has a load of other useful features too, such as an equivalent exposure calculator, and a flash exposure calculator.

I've found Sol to be not only an excellent sunset/sunrise app, but it looks great too and I like the visual representation of the length of the day. Sol also has relative alarms that will alert you X minutes prior to a sun event (sunset, Golden Hour, etc). It can also be set to adjust for your location if you travel. Also check out SunCalc - it's not ...

I live in Colorado, and spend a lot of time around the Rockies. While the mountains do indeed have an effect on the time and length of sunrise and sunset, I wouldn't go so far as to say they eliminate Golden Hour. The old adage that states golden hour hits its peak a few minutes after sunset holds truest in the mountains, although it may be more like 15 ...

Mountains definitely affect the timing of sunrise and sunset. As you mention the sun will drop below a mountain earlier (and rise a little later) than it would on a plain. Still the light can be very beautiful. I am not sure if the length of the good light is affected by mountains, but it is certainly worthwhile to arrive at your location about an hour ...

You have two effects in mountains: When the sun is behind the mountain, your sceen is lit only by blue sky, and by reflection of sunlight from peaks. Late in the day there is very little light reflected from peaks, even though the sun may be 1-2 hours from sunset. Your lighting is bright blue sky. This light has less red in it than a similar period of ...

Here is a screenshot from TPE. Normally this would show the following: Sunset - the time the sun sets Civil twilight - defined as when the sun is below the horizon, less than 6 degrees - brightest stars and planets visible Nautical twilight - defined as when the sun is between 6 and 12 degrees below the horizon - many more stars visible Astronomical ...

I don't know about Iceland, but I do know that in Alert (which is now a weather station in Nunavut, but was the northernmost Canadian Forces Station where we listened to the Soviets at the times I was there), you did run into periods where the sun either never rose at all (close to the winter solstice) or never dipped below the horizon (close to the summer ...

As one of the developers, I feel compelled to tell you about our photography app, GoldenPic. GoldenPic doesn't just give you the sunrise and sunset, it also provides you the blue and golden hours, moon phase, moonrise and moonset times, weather, GPS coordinates, etc. It even lets you save your GPS coordinates to recall at a later day/time and integrates ...

On the iPhone there is a great application called Star Walk that shows you elevation and sunrise/sunset times, either for your current location or a location you pick from the globe. It also shows you rise/set times of the visible planets and the moon. As a bonus in this case (and the main feature of the app in general) it gives you a great map of the night ...
