With the photography project "What nature knows", Rognli draws in references from his affiliation with Arctic Northern Norway, to light, darkness and the seasons. He transforms ordinary landscapes into an enigmatic place to be and takes us on a visual experience in the evening and the atmosphere of the night. In the project he immerses light installations in water, and creates harmony where there is conflict between the elements. He illuminates nature with LED-lights, luminescent material, and uses photographic effects.
