Re: [OM] shutter speed

[Chuck Norcutt]

Googling 60mm mortar muzzle velocity returns number between 439 and 550 
feet per second.  Let's choose 500 fps for a nice round number.  It 
looks to me like the projectile is about 1 foot out of the tube so it 
started emerging from the tube 1/500 second ago.  So I'll guess 1/1000 
of a second shutter speed which would allow it to traverse half it's 
length during the exposure.
