Andy, you must have a formula memorized for this.

 

Assuming none of the cars stop and everyone flies through the intersection at 30 mph, the image frame encompasses 1/2 block, what is the minimum shutter speed needed to prevent the moving cars registering?

Hi all,

 

Could someone please refresh my memory.  What is the aperature/shutter speed combination I would use if I wanted to photograph a busy intersection and not record the moving items(i.e. the cars, et al) ?

 

Thanks for your help
