Great pics valsdad.

You have the Nikon 3400 right? I'm sure you read the directions I posted above. Set it on S and turn the plain black wheel, until in the lower left corner it says 2"
That means 2 second time exposure.

I just figured out, the other thing, you have to hold the shutter button down for several seconds, to make it shoot. Push the button like normal and it won't fire you might have to hold it down for 4 or 5 seconds.

Those pics have me inspired!
