It is often written that dust and manmade pollution are responsible for colorful sunrises and sunsets. Certainly the brilliant twilight afterglows which follow major volcanic eruptions owe their existence to the ejection of dust and other particles high into the stratosphere. If, however, tropospheric dust and haze were responsible for brilliant sunsets, cities such as New York and Los Angeles or London and Mexico City would be celebrated for their twilight hues.

The truth is that tropospheric aerosols (especially when present in abundance) do not enhance sky colors, they subdue them. Clean air is, in fact, the main ingredient common to brightly colored sunrises and sunsets.

To understand why this is so, one need only recall how typical sky colors are produced. The familiar blue of the daytime sky is the result of the selective scattering of violet and blue light by air molecules. "Selective scattering," also known as Rayleigh scattering, is used to describe scattering that varies with the wavelength of the incident light. Particles are good Rayleigh scatterers when they are very small compared to the wavelength of the light.

Ordinary sunlight is composed of a spectrum of colors that ranges from violet and blue at one end to orange and red on the other. The wavelength of this light ranges from .47 um for violet to .64 um for red. Air molecules are much smaller than this (about a thousand times smaller). Thus, air is a good Rayleigh scatterer. In fact, pure air scatters violet light three to four times more effectively than the longer wavelengths. Were it not for the fact that human eyes are more sensitive to blue light than to violet, selective scattering would make a clear sky appear violet instead of blue!

At sunrise or sunset, sunlight takes a much longer path through the atmosphere than during the middle part of the day (angle of inclenation). Because an increased amount of violet and blue light is scattered out of the beam along the way, the light which reaches an observer early or late in the day is reddened.

I do not stay in a big city. The small town is in central South Africa. Some of the cleanest air can be found here and because of the wide open spaces sometime refered to as "Big Sky Country" My house is on the outskirt of town this is the view from my backyard. I don't think I will ever return to the Cities again, the quality of life can not be quantified. I hope you like the post, it's fresh taken half hour ago.

Hi Gerhard, it's very simple and effective, you've made it look very easy. The colours are warm and easy on the eye. This is easily your best sunset shot. Very good work. The note is very good too.

Thanks for sharing, it's a beautiful sunset. It would be interesting to see the same panorama during the day. At first I didn't like the power lines, but when I viewed the large version, they look better.

Very colourful Gerhard.
The colours are very nice and the composition are great.
Very good note.
Very well done.

tres jolie pano de fin de soirée !
les silouhaites des arbres et des pilones emectrique sont du plus belle effet.
par contre j'aurais elever la moitier superieur des nuage pour ne garder que les nuages roses.
good work.

Fantastic sunset Gerhard. Amazing colours and I really like the land scape cropping - it works perfect here as well as the low horizon.

Gerhard, I really enjoyed reading your notes on light as it plays out in the actual sunsets we see. It's great to see where you live through this wonderful sunset captured so well! Thanx for this!!

As you must be happy to live in the similar place, Gerhard!
Have no horizon blocked by buildings as to me, in Montreal. And you see it from your home.
I know that you are aware of your luck to live in such an environment.
Magnificent sunset. I like the presence of these some trees below to the right.
Excellent panorama. Thanx

An excellent sunset shot and even better appreciated with the LP version.
Great colours and nice sillouettes of the trees.
The note is great too.
Well done.

Amazing panorama with saturated, beautiful colours of the sky. You are lucky to live in such place!

Great pano, very warm colors, it would be perfect without the power lines.
Well done Gerhard

Nice photo, nice colours. The sky is too big for me, to keep a part without the red coulours is good idea but for a little less would be good.

And I thought that sunrises and sunsets were just plain and beautiful and now reading your note is see that it is very scientific :) This scene has been superbly captures and I love the note.

Thanks for posting

One in a million shot Gerhard! I'm a fanatic sunset/sunrise photos lover and this shot is outstanding for me! Very fine work! Added to my favorites! TFS!
