I came across this awesome picture of the woods today. It looks like you're running through it - does anyone know how they did this?

Looks like Photoshop's Filter > Blur > Radial Blur set to zoom.

MM beat me to it :D but I concur that is the effect for sure. If they did it a different way the exact effect can be achieved as stated above.

to do it in camera:
zoom in on scene...set for slightly longish exposure, halfway through the exposure, zoom out....will take trial and error, but you can get some great effects

Thanks so much!! I'm not a photographer extraordinaire, but that Photoshop tip was so simple and produces such astounding effects.

Thanks!!
