On my Nikon D3100, it has a max flash sync speed of 1/200th of a second. Why is it that if the flash speed is so incredibly short (much faster than 1/200th of a second), you run into problems if using shutter speeds faster than 1/200 (a shutter blind causing an area of the photo to be darker). In other words, why if the duration of the flash is so much shorter than 1/200th of a second, can't it be synced to flash when the shutter is fully opened at speeds faster than 1/200th of a second??
Another part to this question, the pocket wizards talk about being able to use faster shutter speeds in midday shooting with fill flash, does that function work on a D3100, or is the D3100 always limited to 1/200th?
Do I ever need faster than 1/200th (I was able to freeze a hummingbird wings with that speed).
I have read all sorts of Google posts on flash sync but I must be missing something.
