The other day I posted a rather smashing photo of a Chennai sunset which lit up the sky in purples, pinks, oranges and reds. I referred a question to my fellow blogger, Tom, about why the sky had all these amazing colours. Many thanks Tom for taking the time to answer it!
This was the sunset over Chennai on Sunday evening, taken from my balcony. There was no post-production work done on this photo, it was just snapped with a simple compact digital camera. According to scientists, the reds, oranges and purples are caused by light being scattered by particles in the upper atmosphere, the more particles the more it gets scattered and the ‘blue’ lightwave is lost, leaving the reds and oranges. If there is a lot of pollution like aerosols and all the other crap that us humans produce we’re rewarded with some pretty spectacular sunsets. I’m willing to hear a more accurate and scientific answer though, (Tom, I’m looking at you here!).
