Recipe for a Dramatic Sunrise or Sunset

Are the sunrises and sunsets in your part of the world ho-hum?
If they are, then you could follow this recipe to make them spectacular!
– start with clean air, preferably in the fall or winter season. (You might have to travel somewhere to find these conditions.)
– marvel at the blue of the daytime sky, which is caused by the selective scattering of sunlight by air molecules. This scattering favours the shorter wavelengths of violet to blue.
– consider the much longer path through the atmosphere that sunlight has to travel in the morning and evening. It scatters more violet and blue, which creates the opportunity for reds and oranges to reach our eyes.
– finally, add some clouds to catch the red-orange rays and reflect this light to the ground.

It wasn’t until I investigated the science of the colour of sunrises that I realized that not everyone gets to see such a thing regularly! Now I know how fortunate I am to live in two parts of the world where this frequently occurs.

This week’s WordPress Photo Challenge is Rise/Set

For a good explanation of scattering, see The Colors of Sunset and Twilight.

Question of the day – do you have dramatic sunrises and sunsets where you live? If so, how much thousands of photos have you taken of them?

Faces in the Car Show Crowd

January and February are the best time of the year for the car buffs in Arizona! This year The Car Guy went to Russo and Steele, Silver Auction at Fort McDowell and the Fountain Hills Concours in the Hills. He would have gone to Barrett-Jackson too, but got tired of trying to find a place to park.

I also used several filters on the same photos – the faces are not nearly so recognizable: Faces at the Car Show.
