Everybody left right after the Sunset at Oia, Santorini. We continue to stay and get to enjoy another magical light of all.
“Around 20 to 30 minutes after sunset, sometimes the clouds turn bright orange, or Deep red, or purple, or if you're lucky, a combination of all three. Some of the best shots could be taken after everybody else has gone to dinner. Wait even longer (30 to 45 minutes or more after sunset), and the sky will often turn a vibrant, Deep Blue (and it happens right before night). It only lasts for a few minutes (10 to 12 minutes usually)” - The Digital Photography Book Vol 2 by Scott Kelby
The picture below was taken right before the night (30 minutes after sunset). We were stunned by the scene of Oia in deep blue colour.
