But only if the splash achieves the same height. I'm simply guessing that the additional energy needed to overcome surface tension in the higher viscosity liquid will result in a higher splash.
The formula for tracking velocity against distance is v=√(2gx) where v=velocity, g=gravitational constant and x=distance travelled.
Anyway applied to a water droplet it simply means that if the (rise and fall) of the drop is
2" the exit and re-entry speed is 8 inches per sec. and for
3" the exit and re-entry speed is 11.3 inches per sec.
This has a significant blurring effect at a shutter speed of 1/320 where the droplet may have moved up to 0.035 of an inch unless you catch it at the top and stationary.
That's why it's best to shoot in darkness using a flash. The flash duration can then be thought of as the shutter speed and can be as short as 1/30,000sec. I'm sure each flash unit is slightly different but, as a rule of thumb, you can take full power use as 1/1,000th sec falling to 1/20,000th at 1/32nd power (this doesn't apply to studio flash where flash duration is much longer).
The motor drive won't help either; the action is all over in 1/2sec and anyway, you don't want the vibration. In Manual Mode, prefocus, lock the shutter open and trigger the flash when you hear the droplet hit the water; you'll need patience and persistence to get it right. A chair and a glass of your favourite tipple will help.
I have to get a good flash to do this. I only got the build in flash. Thanks for answer and it is worth a try. With my luck I need a chair and a bottle of my favourite drink before I get the ultimate picture.
