I lugged speedlights and stands down to this puddle on a creek in the middle of the night all by myself. There is flash behind and to the left and right of me and I used a remote just hoping it was working, cause i couldnt see the light or hear the shutter from the distance away I was. Turned out better than I couldve expected. Steel wool using bulb mode with the remote and rear curtain sync for the flashes.
Nikon D7500 - 20mm - f/4 - ISO 100 - 3.8 sec shutter
