I would suggest reading Kev's website for some insight. As he explains, it is not the fast shutter speed that freezes the drop, rather it is the flash. For example, I actually use the Bulb setting when taking my water drop pics. The the flash is set in its shortest flash duration such as 1/64 or faster. The more powerful the flash pop, the longer the flash duration which results in motion blur.
Anyways that's a short synopsis. He does a much better job explaining it and has pictures to show examples.
do you have the link?
i definitely haven't learned the manual settings for my flash yet, as I had it set to whatever automatic metering that it uses when you press the "star" button on the camera and it fires a test flash.
thanks for the info, hopefully that will help a ton!
