Re: [OM] shutter speed

[John Hudson]

Assuming that the camera was a film camera I think it is doubtful that the 
photographer used his finger to trigger the shutter! The chances of getting 
the image just right as the projectile left the firing tube would be 
incredibly long odds.

Isn't it more likely that there were a sound or light activated trigger 
mechanism attached to the camera ?
