Well it would be nice to see what you are talking about that just gets
me "Error (404)".




Link works fine on this end.


Car is not moving backwards...but camera is

Try it again. It might be a Dropbox issue.

OK! That time it worked.

From what I can make out this was a case of two things in motion, your
camera and the subject car.

I suspect this was shot from your vehicle as it passed/overtook the
subject car. You were passing, so your vehicle was traveling faster,
therefore relative to your camera it was going in reverse.
You might have unintentionally added to the effect by trying to pan
right-to-left as you drove by. A left-to-right pan might have
neutralized the speed difference, but you probably wouldn't have been
easily able to turn to your right.

I am also making the assumption that you were sitting in the passenger
seat on the right, as I will credit you for not being reckless enough
to take that shot while driving. :-)

The 0.6 sec @ f/22 exposure also added to the mix. That might have been
stopped down a tad too much resulting in the slow shutter speed
controlled by aperture priority. With your 70-200mm f/2.8, you probably
should have been at f/4-f/6.3. Then your fast glass would have worked
with a frozen capture at 1/1200-1/2000.
...and now that I think about it the length of the 70-200mm would have
made a left-to-right pan very tough indeed.
Still it is an interesting capture.

Thanks. I wasn't trying for a frozen capture. I wanted slow, but not too
slow. I took the shot at about a 45 degree angle.

What? You've never taken a photograph while driving? Wimp.

Taken in the moving flow of traffic.


Did the PO give you reason to reflect on thw wisdom of taking pictures
from a car?
