dear all approaching the last days of the year i thought it funny not only to drink the champagne but also make a photo of the cork "leaving" the bottle in speed have anyone of you done so with the D700 without the help of a sound or other trigger any idea is more than welcome and of course to all of you out there: have a blessed time and a great 2013 cheers !
“There is only you and your camera. The limitations in your photography are in yourself, for what we see is what we are.”
Without a sound or other trigger, your only hope is to set it to continuous high (preferably with an MB-D10) and hope for the best. Kim Western burbs of Chicago P.S. Of course you could try something creative, like aiming the cork at the shutter release or tying a string to the cork attached to your shutter release
Champagne most always "pops" makes a pop sound when uncorked in this manner so with a sound trigger you should be able to capture an image as desired. I would manually focus first to remove the focus lag.
As mentioned I would use the MB-D10 and tell whoever is popping the cork to wait for your shutter to start snapping on continuous high and then open the bottle. If you wait until they open the bottle first, there may be too much of a delayed reaction.
Use alkalines or the newer battery in the grip, if you use the EN3 battery you'll still only get 5 FPS I believe.
It is quite unlikely that you will make a photograph of a champagne cork without a special equipment.
Here is some college physics:
The speed of the champagne cork is somewhere between 40 and 100 km/h, in average around 70 km/h. This about 20 m/s. If you make a burst of photographs, the distance the cork will travel between two shots will be about 4 m, if you use just the camera battery and 5 fps. That makes the chances to capture the cork on the picture practically nil. If you made it it would be a pure coincidence.
You can still try to capture the cork but you will have to use the flash, otherwise the cork will be unsharp due to high speed.
Next, using the "pop" sound to trigger the shutter would not make it since the shutter lag is about 40 ms. You should also add about 10 ms for the sound to reach the microphone at the distance of 2 m. During this time the cork makes about 1 meter and would be out of range before the camera would take a shot.
The only reliable method would be a laser detector and a flash trigger. Take a look how to implement such an equipment here:
A friend of mine, an excellent photographer (http://www.arrigler.com/en/) is always telling me: The photography is always the science of light in connection with inspiration. Engineering mind (I am an engineer as well) is very often needed in order to make a good photo.

What if you changed your perspective. Don't do a side on shot but sit down beside and behind the bottle opener and take the shot at an angle to the trajectory of the cork. Tuff as he k to focus for but maybe you could catch it.
Next, given the speed of sound at 20 °C is approx. 343.6m/s the sound lag at 2m would be approx 5.82ms or at 1m would be approx 2.91ms
Given the shutter lag is 40ms then at 2m the total lag time is approx 45.82ms, the cork would travel 50.4cm or if we place the microphone at 1m the distance would be 47.5cm. The microphone could be placed closer.
Of course this doesn't take into account the lag in the trigger circuit and even if you use a laser detector there is a lag in the circuit. But even if this were instantaneous you would have the shutter lag of 40ms and at 40km/h the cork would travel 44cm.
