This isn't something I've done a lot of, but I've seen some great stuff on here so I thought I'd head out tonight give it go.
Here's the generic motorway shot;
And here are a couple from by the airport (the higher of the 2 trails on this un was a plane landing)
That last one was probably shot on too big an aperture - had a second one on a higher f stop on the go (after waiting 30 minutes in the cold for a fucking plane), but my battery died half way through the shot. Arses.
I've got a lot to learn, but it's good fun.
