I agree, great shots.
Are you saying these were taken at 1/64th of a second ?!
If so is that what the camera came up with - type would be intersting - or as you infer, manual exposure ?
I've worked alongside the press photographers too - everything one sees in films is true, they're utter Piranhas.
I found I got the best results by stepping away a few ( or a few hundred ) yards for a clear shot while they were busy jostling and climbing over each other !
