These two images are the day and night side of sunset. There is no processing apart from some cropping and a slight increase of contrast. The colours are as recorded in raw by the camera. I saw these magical hills after our meal on the Urbino camping in the Marche region of Italy. The view is towards Umbria in the west. The yellow image was shot half an hour before the sun disappeared behind the mountains (it was to the right of this frame), the blue one half an hour after sunset. When I sat there amazed at the show put up before me I did not realise the stark difference in colours because of the gradual change. I think this is what sets photography apart: because it isolates moments in time it strenghtens impressions. The striking colour difference only became apparent to me weeks later, at home when viewing full screen versions of these images.
