This picture is a 15-minute long single exposure captured using my Fuji XT-3 paired with the Fujinon 16-55mm f2.8 lens.
The photo was taken inside a shipwreck of an old cargo ship that used to illegally transport cigarettes. It crashed on this beach about 100 years ago and was been there ever since.
This shipwreck is located just outside Gythio, Lakonia, Greece.
