Hi, quick question about my Nikon D5100.
As an example, say I want to shoot a still of a transparent tank of water with a low ISO (under 500 to avoid excessive noise). The environment is low light so to gather enough light, I lower the shutter speed to say 10 seconds. So it would take 10 seconds for the camera to take the shot and any number of seconds extra for it to process the image. Everything is fine so far but now let's assume I wish to drop an object into the water at the 5 second mark and have the camera freeze this object with it's flash. How would I do this? and is this even possible?
My SB-700 arrived today (but no batteries at the moment!). Would your idea work when the SB-700 is attached to the hotshoe of the camera? As my D5100 will not allow me to use the flashlight off the camera.
You might want to look at additional control devices that are capable to triggering the flash when an event like the object passing a control device. Look at the CameraAxe or Mumford Time Machine, both of which can be used to capture a water drop breaking the surface or 2 water drops colliding.
Gohan, I'm not greatly experienced myself, but you can get an extension lead that will fit the hot shoe of your D5100 and your SB-700 and it is 1.5 meters long. I'm led to believe that up to three of these leads can be joined together. The source of this information id the Magic Lantern Guide for the D5100 by Simon Stafford. I hope this helps.

Enables me to use the SB-700 outside the camera like I could if I had a D7000. Thanks, I am not sure if I will buy it now though, I haven't learnt to use the speedlight on the camera yet. It will be very likely that I purchase this in the future.
Joseph has nailed all of the relevant items: manually fired flash, don't touch the camera during the exposure. The other devices are potentially interesting, but in my opinion for this particular application are just more things to go wrong. I've done almost exactly the same thing (although with smoke instead of water).
