What do they mean “ Recently, scientists in Japan were surprised to find a species of oval squid raised in captivity could change its coat, depending on whether its tank was clean or covered in algae.”…are they students, because I saw this described and demonstrated in 88 in my marine biology class in Hawaii….then we dissected it….then we cooked and ate it as a class. Interesting teacher.

Absolutely not the first time they’ve been “caught” doing this…maybe the first time with high definition cameras, in one specific laboratory condition, with that specific species, raised in captivity, but this is every day behavior for many cephalopods, including squid, and absolutely not a new discovery.

Let’s see them decipher the intense flashings, strobing, color waves, slow fades, etc that they use to communicate and hunt. That might be a first….but I doubt it. Others have studied their insane chromatophores and their amazingly mailable mantles and how they use them for decades if not longer.

This is a neat bit of biology, but to pretend they just discovered this is outrageously dishonest. Get real, people knew squid camouflaged themselves amazingly well long before that guy named Jesus was fathered by a forced pedophilic inception. Almost like saying scientists just discovered newts like it moist, or that water is wet.

The strobe didn't get the kid shot.
The kid got shot because he had a gun, shooting ( him and his thug buddy) in the middle of the night .
He should not have run.
Chased by cops with gun in hand and ditching it and turning around at last moment got him shot. The kid is 90% responsible for his death.

Strobe, cop and all other factors 10%.

This is a non story except by fake media to divide Americans.

Awesome, but they need to get rid of the strobes for filming and sync the speed with the camera shutter speed. I could barely see what's happening.

Actually it is called Animation, and Cyrus is a master of it. Although it is probably a mixture -- nobody is a purist anymore.


From Wiki:
Animation
A style and a technique where you imitate film characters being animated by stop motion. The technique of moving rigidly and jerky by tensing muscles and using techniques similar to strobing and the robot makes it appear as if the dancer has been animated frame by frame. This style was heavily inspired by the dynamation films created by Ray Harryhausen, such as The Seventh Voyage of Sinbad (1958).

And if you look at the list of male contestants, you'll see Cyrus having given himself the label of "animation."

Canon manages it by strobing the flash repeatedly though the moving slit. This is called HSS flash as I recall.

It lets you shoot super fast exposures, get huge apertures and still use some fill.

From description

In person uses a strobe light to get this effect. For this video, rather than using a strobe, the camera was set to a very short shutter speed (1/4000 sec) in order to freeze the spinning sculpture.

#1 Its not fake.
#2 this is probably one of the first couple of full runs, no one but the home owners even know about it.
#3 It is not actually that difficult. The kits to synchronize these lights have been out for a decade now. In a case like this I would;

a) Get permission to handle everyones lights for the year.
b) Using the same kit, I wouldn't get too fancy, gutter icicles, trees, garage outlines, not much more for each house.
c) only need to make one routine, this routine can then be loaded into all houses with only the need to tweak the strands of lights used in each group.
e) syncing would be no problem with an internet aware kit that synchs its internal clock online.

The place turns into kind of a strobe mess because there are not many types of light groups to alternate between, but that can wait for next year. Great effort.

My favourite was the Xenon strobe lamp

if you didn't see irreversible at an actual cinema, on a big screen, you mostly wasted your time.

the whole movie is shot in a sickening, nauseating way, with the camera twisting and turning all the time... punctured by extreme acts of violence. on the big screen, it is actually physically overwhelming.

the movie is told backwards, which makes the ending all the more hideous.

the closing shot of the film is a slow zoom out from a rotating sprinkler, as the happy couple lounges about in the summer sun... the camera starts rotating with the sprinkler as a strobe effect gets more and more intense. seeing it on the big screen, it was repulsive -- i nearly barfed.

i think this movie is incredible (and utterly depressing), but people's reactions to it really worry me. a powerful message is completely lost on these idiots.

You can make this effect appear to the naked eye under a strobe light.

it's an example of the stroboscopic effect -- an optical illusion whereby the stream of water is vibrating at the same frequency as the video is running (presumably 24 fps), making it seem like the water is "streaming" in a spiral, when it's only those droplets captured by the video that are vibrating with the sound to make it appear that way. It's the same reason car wheels and propellers appear to change direction as they speed up or slow down when seen on film or through a strobe light.

Still, knowing how it works doesn't make it any less cool!

On a side note, first song is Drowning Pool - Bodies, which was allegedly used by interrogators in Guantanamo bay, along with strobe lights. Not a hundred percent sure how recreating the typical concert could be considered a form of torture, but I'm not expert.
