Variable Speed Limits

[Alps]

I found an image on Flickr and have no idea whether it's authentic. See the second image on this page (won't allow direct linking).

This one? http://www.flickr.com/photos/wxkeith/6288100978/

And that is what the Turnpike signs look like. Trust me. I've seen them activated already.

Thanks, I haven't been on there in a year or two. But do the standalone speed limit signs look like that too? That's really the subject of this thread, after all.

Here's one of the white-on-black...incidently taken during a snowfall back in Febraury.  As the snow wasn't sticking, the speed limit remained normal.

You need a very slow shutter speed to do it properly - and thus a bunch of other settings to compensate as best you can. Electronic signs are tricky beasts due to the cycling.

It also tends to work better the farther back you are. Not sure if there's an optical reason for this, or if higher zoom changes other camera settings.

That makes sense, but not sure if I could do that in motion without getting some sort of motion blur.

I'll be sure to keep this in mind the next time I want to photograph a VMS like this.
