Well, the Fuji 602 (and I assume the same would be with the 7k, 5k, 5xk, and all of the same bodied cams) has no shutter at all. It is totally electronic. The CCD reads data all the time, and the capture is just a fraction of a second of read time from the CCD.
Would I need to find the tech specs on the flashes that I have to determine the duration of the flash blast and then convert that into the maximum shutter speed available, since I don't have to worry about the leafs or a partially open shutter?
Fascinating stuff here ! Thanks! |

That certainly solves the sync problem... To be honest I was quite suprised when I found out my old G5 had a mechanical shutter. I suppose the reasons for/against a mechanical shutter on a non-full frame sensor is up the R&D departments...

I was just wondering how these shots are made, specifically how you manage to press the sutter at the exact right time when you are taking a picture at 1/2000 of a second. Do you just try again and again and again until you luckily hit one shot where the shutter is correct or what technique do you use? |
I'd vote for the again and again technique. For example:
Looks simple enough but took about 55 shots to get one with the cute little spiral at the top I liked.
Regular coffee was not hot enough to produce the steam I needed so I took and boiled the coffee in a pan first, poured it from the pan into the coffee pot and then from the pot into the cup for every two or three shots. :)

I emailed someone I know does a lot of these shots and he told me that at first he just did what most people seem to do, just shoot again and again and again but he got tired of that and found a device that uses a laser to detect movement and that is used to trigger the shutter at VERY precise times. He said he bought it about 2 years ago and paid about 600$ for it but he wasn´t at home and didn´t remember the brand name.
Anybody have a clue on where I could get one of these laser triggers? |
Not a laser per se, but they have other than sound triggers - this one can 'see' a string or other thin object. All you would need would be a IR sender/receiver and break the beam or perhaps a sonar home alarm sensor - intead of triggering the alarm siren it triggers the flash...hmm, i got one of those...

For the water drop shot I did, I used the 2 second timer on the camera and attempted to time the drop accordingly. It seemed to work very well, out of 15 attempts, 12 of the drops were in frame and I just picked the best one.
