  1. History of Digital Cameras • First there was the camera (19th century) • Then there was the movie camera • Then there was the video camera From The Little Digital Camera Book, Baron, C and Peck, D

  2. History of Digital Cameras • Then NASA wanted to send pictures back from the moon (or wherever they wanted to go) • But there was analog noise • So they converted the analog signals to digital From The Little Digital Camera Book, Baron, C and Peck, D

  3. History of Digital Cameras • 1972 the first patent for an electronic camera • 1981 Sony develops the Mavica electronic camera • Analog video frame capture • 1986 Kodak develops the first megapixel camera • Verrrrry expensive and had a 5x7 limitation From The Little Digital Camera Book, Baron, C and Peck, D

  4. History of Digital Cameras • 1990 Kodak produces the Photo CD • A proprietary technology for digitizing slides, negatives and prints • Saved files to a CD • This popularized digital images • 1991 Kodak created a 1.3 megapixel (journalists) From The Little Digital Camera Book, Baron, C and Peck, D

  5. History of Digital Cameras • Apple develops the first consumer level digital camera about the same time • Digital scan backs and digital capture backs were being developed during the 90s for portrait and catalog photography From The Little Digital Camera Book, Baron, C and Peck, D

  6. History of Digital Cameras • Late 1990s saw the development of 3,4 and 5 megapixel comsumer and prosumer cameras • These cameras can produce an 8x10 for less than $1000 From The Little Digital Camera Book, Baron, C and Peck, D

  7. What is a Digital Camera? • What is a pixel? • What is a megapixel? From The Little Digital Camera Book, Baron, C and Peck, D

  8. What is a Digital Camera? • 1 megapixel = 1,000,000 sensors = 1,000,000 pixels • The more sensors the finer the detail and the larger the print • Each sensor has three filters • Red • Green • Blue • Open the shutter and the camera records how much of each color recorded on each sensor From The Little Digital Camera Book, Baron, C and Peck, D

  9. Film Advantages • Resolution (getting better) • Shutter Latency • Capacity (just different) • Batteries (a real problem) • Cost (still a factor but dropping) From The Little Digital Camera Book, Baron, C and Peck, D

  10. Digital Camera Advantages • Immediacy (see it now) • Usability (with a computer) • Reusability (storage card) • Duplication (every file is the original) • Adaptability (print or web or email) • Flexibility (remove a cast, adjust the flash) • Size (not dependant on the size of the film roll) From The Little Digital Camera Book, Baron, C and Peck, D

  11. Next week • What do you really need? From The Little Digital Camera Book, Baron, C and Peck, D
