Hi,
Got my new Nikon D80 a few weeks back and I think i'm ready to start playing around with some HDR compositions. I am aware of the process, and am going to teach myself through online tutorials etc... but I have one question.
I know the aperture must remain the same, just change the shutter speed with 3 exposures at +2/-2 EV etc....
My question is, how a singe image is captured with 3 exposures and not experience blurring.
Take this picture as an example.

If that is a true HDR edited photo, how do you get the freeze shot over 3 exposures?
Is it as simple as continuous mode with very high shutter speeds? If anyone has any expertise or knowledge on the subject, I'd love to know.
Cheers,
James.
