Put exposure on b and hold it open for 45 seconds. Or something.
UH......................Okie Dokie.
What kind of camera? B is for bulb. Old school for opening the shutter as long as you hold it.. LOL
Nikon 3400, Nikor 70-300 Lens.
Black if that helps.
Oh, if I'm going to hold the shutter open that long, I better invest in a tripod or see if the one for my spotter would work.
Maybe I can rest it on a fencepost and pray.
