  • 2. Camera Obscura• The camera obscura is a Latin Word for darkened room.• A guy called Aristotle noticed How light passing through a small holeinto a darkened room produces a image from outside on theopposite wall back but upside down during a Partial eclipse sun• Then in the 10th Century ,Arabian Scholar Al Hassen used• The camera obscura to show how light travels in straight linesIn the 13th Century, the camera obscura was used by astronomers•to view the sun.•9/21/12
  • 3. Louis DaguerreA professional scene painter for the opera with an interest in lighting effects, Daguerre beganexperimenting with the effects of light upon translucent paintings in the 1820s.He regularly used a camera obscura as an aid to painting in perspective, and this led him think about waysto keep the image still.The French physicist created the daguerreotype, a process of transferring photographs onto silver-coatedcopper plates.According to writer Robert Leggat,Louis Daguerre made an important discovery by accident. In 1835, heput an exposed plate in his chemical cupboard, and some days later found, to his surprise, that the latentimage had developed. Daguerre eventually concluded that this was due to the presence of mercury vapourfrom a broken thermometer. This important discovery that a latent image could be developed made itpossible to reduce the exposure time from some eight hours to thirty minutes . 9/21/12
  • 4. Joseph Nicéphore Niépce Joseph Nicéphore Niépce made theFirst ever picture in 1822 of Pope Pius VII•This picture is the only surviving picture of his earliest pictures•9/21/12
  • 5. William Henry Fox TalbotWilliam made the first negative/positiveprocess in 1839 he refers this as photogenicDrawing. This is used in modern photography 9/21/12
  • 6. James Clerk MaxwellJames Clerk Maxwell was one of the greatest scientists who have ever lived, hemade the first permanent colour photograph in 1861.He did ground breaking work with light,colour and imagery and by spliting lightinto green,red and blue. He could reproduce any coloured imagery 50 yearsbefore anyone else9/21/12
  • 7. High Speed PhotographyThe Society of Motion Picture and Television Engineers defined high-speed photography as anyset of photographs captured by a camera capable of 128 frames per second.High-speed photography can be considered to be the opposite ofTime-lapse photography. The first is that the photograph itself may be taken in a way as toappear to freeze the motion, especially to reduce motion blur.The second is that a series of photographs may be taken at a high sampling frequency or framerate. The first requires a sensor with good sensitivity and either a very good shuttering systemor a very fast strobe light. The second requires some means of capturing successive frames,either with a mechanical device or by moving data off electronic sensors very quickly.The first practical application of high-speed photography was Eadweard Muybridges 1878investigation into whether horses feet were actually all off the ground at once during a gallophttp://youtu.be/UrRUDS1xbNs9/21/12
  • 8. Eastman KodakKodak was founded by George EastmanIn 1889.George Eastman invented dry, transparent, and flexible, photographic film (or rolled photography film)and the Kodak cameras that could use the new film. Pre-loaded with enough film for 100 exposures, the Kodak camera could easily be carried andhandheld during its peration..After the film was exposed (all the shots taken), the whole camera was returned Kodak company inRochester, New York, where the film was developed, prints were made, new photographic film wasinserted, and then the camera and printswere returned to the customer. 9/21/12
