...best magazine photographers go everywhere, shoot everything. For the most part they are represented by one of the six major agencies- Sygma, Magnum, Gamma-Liaison, Sipa, Black Star and Contact- which, for a fee (usually 40% to 50% of sales), play mother and salesman, lining up buyers throughout the world. Most of the agencies have their headquarters in Paris, and Paris is also home base for many photojournalists. "Geographically, it's the ideal place to be," says Robert Pledge, president of Contact. "It's halfway between Washington Moscow, Hamburg and Madrid...
...sense, photojournalists today are competing against all the news pictures that have ever been taken. Their ability to bring back images of war, disaster and suffering has had over time, a desensitizing effect. Says Floris de Bonneville, Gamma's picture editor in Paris: "The real revolution in photojournalism is in the readers' fatigue. They are no longer shocked or surprised by anything." Contact Partner David Burnett, 34, understood this when he went to Cambodia to photograph refugees. "It is easy to make pictures of people starving," he says "I wanted to take a picture that people would look...
...spectra can also be created by directing a light beam or, say, X or gamma rays at an object. As the radiant energy strikes the atoms, their electrons hop from one orbit (or, in the language of quantum mechanics, one energy level) to another, absorbing or emitting light at specific frequencies. Such spectra yielded invaluable data about atomic and molecular structure...
...inhales or is injected with a biochemical, for example glucose, which is the brain's main source of energy, tagged with a telltale radioactive substance that emits positively charged particles. These positrons, when they combine with negatively charged electrons normally found in the body's cells, emit gamma rays that can be detected by a scanning device. Collected and translated into color-coded images, the resulting patterns indicate the intensity of metabolic activity. Because the radioactive substances are so short-lived, anyone undergoing a PET scan is exposed to very little radiation...
