"What are the neutral density filters for, though?"

I see ND filters having two applications. One would be when varying light 
balance between two or more flashes. The other would be when doing closeup 
work. The output of electronic flashes is controlled by varying the length of 
time the flash is "on". Typically this duration varies from about 1/1000 sec 
on the long end to about 1/50,000 sec on the short end. If 1/50,000 is still 
too long, an ND filter is in order.

Hope this helps,
