Hello, On http://www.gphoto.org/doc/remote/ it's stated that "Nikon DSLR: We do not know how to do Bulb capture yet.
At least on my Nikon D3400: gphoto2 --set-config shutterspeed=52 && gphoto2 --set-config bulb=1 --wait-event=[time] --set-config bulb=0 works as expected. Cheers! -- Justin T. Leniger justin.leni...@gmail.com
