This 'unreal' image was shot in-camera using a complex dual focal-length long-exposure technique – using a 13-year-old DSLR in complete darkness

Dead trees on the edge of the Zahara de la Sierra reservoir, southern Spain, photographed at night using a dual focal-length long-exposure technique.

Nature and wildlife photographer Juan Jesus Gonzalez Ahumada has been internationally recognized for his surreal image, The Souls of the Swamp, which earned a finalist spot in Close Up Photographer of the Year's 'Death & Decay' challenge – captured with a technique many photographers have yet to try.

Armed with a DSLR from 2012 and a 70-300mm zoom lens, Gonzalez Ahumada photographed dead trees on the edge of the Zahara de la Sierra reservoir in southern Spain.
