These are pretty much the same shot down at Druidston Bay the other night but I thought it was interesting to show how the light changed over the course of 20 minutes between the first and last shot here. With the sun still above the horizon, shades of gold light up the clouds and give the wet sand a metallic sheen. As the sun dropped below the horizon then the gold is replaced by softer shades of pink and blue before twilight means blue takes over completely. It's then a walk back up to the car as dusk precedes night.
It's always worth hanging around after the sun has left the sky. Quite often a skyscape is made up of different types of cloud that hang out at varying altitudes. As the light changes angles, the dropping sun can still illuminate the underside of the highest clouds even when it has dipped below the horizon. On the best days it can be kaleidoscopic as different layers are revealed and new parts of the clouds are illuminated as they scud and fragment across the sky.
Which one is your favourite? I like the pastel tones that remain after the sun has gone.
