So I was off work one day when the sun was going down, and it was foggy (but clear without much clouds) and I noticed that the setting sun coloured the entire sky with a wide range of shades of orange, creating a beautiful backdrop to the cityscape. Shame that I only saw that when I was driving!
My question is, does fog actually helps create this shades of colours during dawn or dusk, similar to being a gigantic diffuser?
Like many, I always love the scene of a sunrise/sunset, the colour is simply lovely. However I do notice that sometimes the saturation is low and it only showed a tint of yellow before going dark, where sometimes you get this saturated sky with deep orange to golden colours of the sky. How does fog affect the sunlight in these situations?
