Here is the tech from the author of the pic, Peter Murphy
*****
...with overhead crowd shots like this one the action level is high and very difficult to capture in a few shots -- the main problem is misstitches where the people have moved
last week I tried just making more shots -- take a shot,
turn, stop, take another shot -- and 6 shots gave better
results than my normal 4
but half the time at least the scenes I was shooting were
unstitchable the trouble was the interval between the shots was too great so yesterday for this scene I tried setting the camera to continuous and tried to shoot the sequence while turning round continuously with the shutter button held down
I set the frame rate to 3 fps so that in the time it took to go round (without getting dizzy) -- ie 3 seconds approx-- l would have 10 shots. 10 shots is the buffer size for the D1 at max quality so this pano was shot with 10 shots and handles motion better
.. the Chinese guy in the suit close to the camera walked
past me through the sequence
I looked at the shots and worked out that 7 of them were the
minimum I needed to make a stitchable scene
so I used those 7 the 250th of a second exposure I used was not fast enough to get absolutely crisp shots (except for the first one where I was stationary) -- but 500th will be fine
