I'm just thinking about the time it took to set the camera up and wait
for the right moment. Lightning photos are always interesting to look
at, but high-speed video is something else....

You know what might be cool?
TIME-LAPSE PHOTOGRAPHY.
I have no idea how you'd do this automatically, but hypothetically all
you need is an ordinary still camera and the patience of a POV-Ray user...

I've done that before.... I'll have to dig up the stills and rebuild the
movie one of these days. I watered a plant, then filmed it over a period
of 24 hours. It's amazing how much a plant moves during the day.

I'm not sure how a time-lapse photo of something so quick would work....

Oh, some cameras you can control via USB (I think all DSLR and some
others) and you could set up a laptop and do it like that (considering it
doesn't rain and your laptop doesn't run out of power during that
time :)). For Nikon (and for Canon as well probably) there are also some
remote controls which have a setting for taking a picture in certain
intervalls.
There was a cool webpage of someone doing HDR Timelapse photography with
a moving camera. He had mounted the camera on an electrified telescope
mount and could control the camera as well as the telescope mount. I have
to search, if I can find a link.

No, I mean... High-speed photography requires specialised equipment.
Time lapse only requires a regular camera. So do time lapse [of
something else].
But since you comment... take a long exposure of a night sky, and you
get quite an impressive effect. Ever see those photographs with 25
lightning strikes in the same image? Long exposure. Several flashes
captured in a single frame. (This *also* requires special equipment,
mind you...)

Yeah, plants writhe around alarmingly much, actually. Heh, you could
even film paint drying... Might be a bit boring tho.

Really? My camera can do that. All that's needed is to hold the shutter
button down. SLR cameras have been doing that for decades.

Well, yeah, you need a camera where you actually have the ability to
control the shutter speed. Most cameras don't let you do this at all.
And even the ones that do, the maximum duration is usually 0.1 seconds
or something. Not 20 *minutes*...
Hence, "special equipment".

Yeah. It's usually the higher end cameras that say "Let me know when you
want to close the lens, eh?" :-)

OIC, it wasn't clear you were changing subjects. ;-) I've done time-
lapse photography with my digital camera - built-in setting for it.

Yeah, I've seen that done as well - my camera also can do up to a 25
second exposure, but Canon cameras with CHDK installed can do even longer
times IIRC.

The full movie is actually very nice steampunk. :-) The fast-forward

Isn't that like claiming an "entry-level particle accelerator" is not
"special equipment"? :-P

If a camera, that cost 300 euros at 2005 while bought as new, is special
equipment, then possibly yes.

Heh. SLR is much, much cheaper than it used to be...

Yes, if we look back enough. Today I'd say you can't get a decent SLR
for 300e from Finland, since they are all D-SLR's now. F65 still uses
35mm film.

Mm, New from Fischer-Price: My First Particle accelerator: Comes with
everything needed to build your very own proton accelerator in you own
home. Comes complete with 15MW generators, bubble chamber, and a
large-scale farm of analysis computers and data collection equipment. Be
the first on your block to discover the enigmatic Higgs Boson.

I'd guess though that at a university with a strong natural science
branch, they wouldn't call their own local particle accelerator "special
equipment" - because there's actually not much magic in, say, a
Van-de-Graaf- or even a Tandem accelerator, let alone a small Cyclotron,
and a university might well be capable to "DIY" such a thing if they set
their mind to it. (The basic technology has been around since the '30s
of the last century.)
What they /will/ call "special equipment" are probably all the
accessories: Sputter (ion) sources, particle detectors, data analysis
electronics and stuff like that; and they'll be very proud of each of
those thingumajigs they produced themselves. (At Cologne university, for
instance, they develop their own signal processing hardware, including
custom ASICs; they also tried to roll their own detector crystals, but
failed...)
