Relatively insensitive film, with a correspondingly lower speed index, requires more exposure to light to produce the same image density as a more sensitive film, and is thus commonly termed a slow film. Highly sensitive films are correspondingly termed fast films. In both digital and film photography, the reduction of exposure corresponding to use of higher sensitivities generally leads to reduced image quality (via coarser film grain or higher image noise of other types). In short, the higher the sensitivity, the grainier the image will be. Ultimately sensitivity is limited by the quantum efficiency of the film or sensor.

The Warnerke Standard Sensitometer consisted of a frame holding an opaque screen with an array of typically 25 numbered, gradually pigmented squares brought into contact with the photographic plate during a timed test exposure under a phosphorescent tablet excited before by the light of a burning Magnesium ribbon. The speed of the emulsion was then expressed in 'degrees' Warnerke (sometimes seen as Warn. or W.) corresponding with the last number visible on the exposed plate after development and fixation. Each number represented an increase of 1/3 in speed, typical plate speeds were between 10 and 25 Warnerke at the time.

Michael froze as he heard the voice on the radio saying that a man had been murdered by a bullet that had come from the sky. Thinking that the shot they had fired possibly was the shot that killed Mr. Ward, he immediately drove off. For the next two months, Michael and Joe hid the secret that the bullet had actually shot Mr. Ward.

During this time, Jenna Ward started to realize life without her father. While Jenna mourned the death of her father, a strange boy started to appear at the front steps of the church. After many nights of watching this boy, she finally recognized that it was Michael who was sitting on the steps every night.

After months of finding out where the shot came, the police arrived at Michael's house. His dad mentioned the gun that Michael had received from his grandpa at his birthday party. Michael told the police that Joe had borrowed the gun. Upon this, Joe said that the gun had been stolen out of his car along with his CD player. After the police were gone, Michael met Joe and told Joe the gun was under the wood pile in his backyard.

One day , Michael came home to find the police searching his backyard with metal detectors .When the Sergeant went into the woods behind the house , he came out with a bullet that Joe and he had shot off on his birthday .The bullet matched the one that they had recovered from Mr Ward , but without the gun , the police could not place Michael as the killer.

With the pressure increasing .Michael finally broke down and realized he had to give up .On a Saturday morning , he went to Jenna's house to confess to her and her mother and then turned himself in .

"How many common English words were invented by Shakespeare?" How long did it take people to find the answer to this question 15 years ago? And now! you can google it and find the answer immediately! Google is the most popular Internet search engine in the world. It was invented by two students, Larry Page and Sergey Brin. They met in 1993, when they were studying computer science at Stanford University, USA. They dreamed of producing something that could also answer any question in seconds. Internet search engines at that time were slow and gave many websites that weren't useful. In January 1996, Page and Brin decided to make a better and faster search engine. They thought the results should be based on the most popular websites. Nobody would give them money for their project, so they used their own money. They also borrowed money from family and friends. Then, in 1998, they were given a _ for $100,000, and they started their own company. Their first office was in a friend's garage. The company's name is Google, a word which comes from mathematics. A "google" is a very high number---- 1 followed by a hundred zeros. The google search engine was soon used by thousands of people worldwide because it was fast, easy and correct. By 2002 it was the biggest search engine on the Internet. Now, more questions have been answered by Google than any other Internet service, from sport to science, and from music to medicine. Google hopes that in the future all the world's information will be put on the Internet, so that everybody can find everything.
