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


Film advantages l.jpg

  • 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


Digital camera advantages l.jpg
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)
