More than 70 years ago, the M.I.T. electrical engineer Harold (Doc) Edgerton began using strobe lights to create remarkable photographs: a bullet stopped in flight as it pierced an apple, the coronet created by the splash of a drop of milk.

Speed of Light Lingers in Face of New Camera

SLOW DOWN M.I.T.'s camera captures light particles seemingly in motion by using repeated exposures, creating a “movie” of a nanosecond-long event.

Now scientists at M.I.T.’s Media Lab are using an ultrafast imaging system to capture light itself as it passes through liquids and objects, in effect snapping a picture in less than two-trillionths of a second.
The project began as a whimsical effort to literally see around corners — by capturing reflected light and then computing the paths of the returning light, thereby building images coming from rooms that would otherwise not be directly visible.
“When I said I wanted to build a camera that looks around corners, my colleagues said, ‘Pick something that is more safe for your tenure,’ ” said Ramesh Raskar, an associate professor of media arts and sciences at the Media Lab. “Now I have tenure, so I can say this is not so crazy.”
Dr. Raskar enlisted colleagues from the chemistry department to modify a “streak tube,” a supersensitive piece of laboratory equipment that scans and captures light. Streak tubes are generally used to intensify streams of photons into streams of electrons. They are fast enough to record the progress of packets of laser light fired repeatedly into a bottle filled with a cloudy fluid.
The instrument is normally used to measure laboratory phenomena that take place in an ultra-short timeframe. Typically, it offers researchers information on intensity, position and wavelength in the form of data, not an image.
By modifying the equipment, the researchers were able to create slow-motion movies, showing what appears to be a bullet of light that moves from one end of the bottle to the other. The pulses of laser light enter through the bottom and travel to the cap, generating a conical shock wave that bounces off the sides of the bottle as the bullet passes.
The streak tube scans and captures light in much the same way a cathode ray tube emits and paints an image on the inside of a computer monitor. Each horizontal line is exposed for just 1.71 picoseconds, or trillionths of a second, Dr. Raskar said — enough time for the laser beam to travel less than half a millimeter through the fluid inside the bottle.
To create a movie of the event, the researchers record about 500 frames in just under a nanosecond, or a billionth of a second. Because each individual movie has a very narrow field of view, they repeat the process a number of times, scanning it vertically to build a complete scene that shows the beam moving from one end of the bottle, bouncing off the cap and then scattering back through the fluid. If a bullet were tracked in the same fashion moving through the same fluid, the resulting movie would last three years.
“You can think of it as slow motion,” Andreas Velten, a postdoctoral researcher who is a member of the design team, said during a recent technical presentation. “It is so much slow motion you can see the light itself move. This is the speed of light: there’s nothing in the universe that moves faster.”
Dr. Raskar says the technology has a variety of promising commercial applications. Last year, for example, one of his graduate students, Jaewon Kim, published a thesis envisioning portable CAT-scanning devices.
Dr. Raskar said he could also envision smartphone software that would capture and interpret reflections from, say, fruit. “Imagine if you have this in your phone about 10 years from now,” he said. “You will be able to go to your supermarket and tell if your fruit is ripe.”
Until now, picosecond speeds have largely been the province of an elite group of scientists clustered at the nation’s weapons laboratories.
At Lawrence Livermore National Laboratory, Gary Jones is an optical physicist who builds ultrafast imaging systems that help characterize the first microseconds of events like laser fusion and nuclear explosions. “To get a two-dimensional image within a picosecond means you have to have a lot of electronics moving really fast,” he said.
For Dr. Raskar — who optimistically calls the project “femto photography,” using the term for quadrillionths of a second — it is about more than just engineering or science. “We were inspired by looking at the world in a unique way just because we could,” he said.
The system allows the naked eye to see information that has until now been rendered as data and charts. The proper analogy is to the way astronomers use instruments like radiotelescopes to create images with “fake” colors to see things in new ways — or to the original inspiration of Eadweard Muybridge, the 19th-century British photographer who achieved a new understanding of a horse’s gait by creating a camera array with electromagnetic shutters set off by tripwires.
“We’re still trying to get our heads around what this means,” Dr. Raskar said, “because no one has been able to see the world in this way before.”

Anton/Bauer Delivers Emergency Batteries to Panama Location
Anton/Bauer Delivers Same-Day Batteries And Chargers To Crew During Remote Shoot In Central America (Panama)
|
(Atlanta, Georgia--February 22, 2011) While on location in Panama shooting the blue water fishing and hunting TV series, The Best & Worst of Tred Barta, for the Versus Network, owner and executive producer of the full service video and film production company, R/Wheeler Communications, Bob Wheeler, and crew found themselves with an incompatible power source. Quick thinking and a call to Anton/Bauer customer service resulted in a saved shoot and on time delivery to his client. Anton/Bauer, a brand of The Vitec Group, and the world’s premier provider of batteries, chargers, lighting and other mobile power systems for the professional broadcast, video and film industries, was able to locate multiple batteries the same day and delivered them to a propeller plane waiting to take them to a remote offshore location. If your future plans include Panama as a location, contact Verite Producciones which offers production services to the visiting producer in Panama.

Film Festival in Panama ((:TAG International Film Festival of Panama, Film Festival Panama, Panama, Verite Producciones))
Gears are turning for a major film festival next February International Film Festival of Panama Over the years Panama has hosted the ICARO Central American film and video festival, but for a number of reasons --- one of them the country's reputation as a distribution center for pirated videos, another the legacy of the now abolished Censor Board, yet another the prevailing anti-intellectual attitudes of the rabiblanco wannabe aristocracy --- Panama has been shunned by Hollywood, both as a place to make films and as a venue to show them off at film festivals. Pamama's tiny size as a media market also hasn't helped the cause. But this is not a static world. The world's most prolific film industry is in India, not the United States. The spaghetti westerns were one of the early waves of the US film industry moving offshore, and, with a number of US states joining Canada in giving subsidies for the motion picture arts, Southern California is ever less the place where films are made in North America. And then in North America and elsewhere overseas there are ever more theater people, and fans, who disregard the trash that this country's commercial television networks buy and notice the creative stuff appearing on Panamanian stages, and the appetite of many of the movie-goers here for non-Hollywood fare. So, Panama as a world film capital? Neither Bollywood nor Hollywood are trembling, but a higher profile for Panama is not at all far-fetched.Film producer and the creator of the Toronto International Film Festival Henk Van Der Kolk sees the possibilities and he's teamed up with Canadian resident of Panama T. Rob Brown (who has a background in arts marketing) and noted film festival programmer Diana Sanchez to put together the International Film Festival of Panama, which is scheduled to happen in February of next year. The government has offered its support, which may or may not help with many of Panama's creative people but will provide some needed resources. The Canadian Embassy and COPA Airlines are also on board. Festival organizers are talking about a budget of $2.6 million in cash and in-kind services, about half of which they expect from governmental sources. A major focus will be on marketing to Canadians, who might be expected to use the festival as their opportunity to escape their frigid February weather in favor of sunny Panama. The international publicity will be especially directed at Toronto. It's too early to know what will be showing. Stay tuned. ![]() Rob Brown, Rainer Tuñón, Alexandra and Damien Alcázar, and Henk van Der Kolk |
Real World turns 25
At 25, MTV's "Real World" challenged to stay fresh
By Reuters
LOS ANGELES (Reuters) - Nineteen years ago, TV producers Jonathan Murray and Mary-Ellis Bunim put seven ordinary 20-somethings from different backgrounds into a house and launched the phenomenon known as reality television.
On Wednesday, their show "The Real World" embarks on its 25th season on MTV with much the same format and a new set of young men and women living together under one roof in Las Vegas. But now the series is just one of several hundred reality shows a year on U.S. TV, and it faces the same dilemma people do as they age, becoming old-fashioned.
"I always had a healthy respect for real people and that they would give me more interesting stories than I could ever try to fabricate," Murray told Reuters.
"But I had no imagination in 1992 that 'The Real World' would last this long. When we first sold the idea to MTV, it was a great experiment. It was a unique idea.
"It has been able to stay fresh because it is always reflecting where young people are, and what is important to them at the time," Murray added.
In its early years, "The Real World" pushed boundaries and drew attention as the stories of its young roommates revealed the attitudes of a new generation toward race, AIDS, immigration and abortion, among numerous cultural touchstones.
In 2008, The Real World`s spinoff, "The Island" came to Panama`s Bocas del Toro province. Verite Producciones provided production services for this month long shoot.
