Jewels of the night

“Jewels of the night”. Pixinnì watchtower and Cala Segreta, southern Sardinia. The darkness of the night and the clear sky (Sardinia is the Italian region with the least light pollution, i.e. dark nights) offer two jewels: the clearly visible core of the Milky Way and the transparencies of the crystalline waters enclosed among the rocks of the cove.

This nocturnal landscape required, in addition to the usual planning, the use of two distinct techniques: to capture as much light and details of the Milky Way as possible, without having to deal with massive digital noise (due to the high ISO sensitivity) I took 18 shots of the sky, subsequently aligned and merged in post production. As for capturing the foreground (rocks, sea and tower) I’ve shot a single exposure, adding a bit of light painting withe use of a LED “magic wand” set with a suitable color temperature, thus illuminating all the details that can be seen in the photo. Using Lightroom and Photoshop, I then proceeded with the editing and the adjunstments of colors and brightness of the foreground and sky.
