The Digital Camera-A Revolutionary Technology.

"Say Cheese!" The art of picture taking (photography) has been a part of our lives for 100's of years. During ancient times, images were created on the wall by passing light through a tiny pinhole (Marples, 2008). History tell us that a photo sensitive compound was created by accident when in 1727 Professor J. Schulze mixed chalk, nitric acid, and silver in a flask and noticed darkening on the side of the flask when it was exposed to sunlight (Greenspun, 2007).
As time progressed, the progression of photo technology evolved to what we now know as the digital camera. According to Dunleavy 2006, it was in the 70's when researchers began exploring the possibility of converting light to create digital images. "Digital camera technology is directly related to and evolved from the same technology that created television images" (Bellis, n.d) Futhermore, Bellis contends that this first digital systems was a Nikon F-3 camera by Kodak in 1986. It was "equipped with a 1.3 megapixel sensor" (today, we are up to 12 megapixels). However, some digital camera timelines show that the first digital camera was the Sony ProMavica MVC-5000 in 1989. Dunleavy 2006 posits that it was not until 1991 when the first professional digital camera system (DCS) was introduced by Kodak (Dunleavy, 2006).
Regardless of when the first digital camera was invented or who introduced it to the market, its development has seen several progressions over time. I would like to introduce a terad that show and how this technology enhances, obsoletes, retrieves, and reverses. It will, therefore, helps us to understand the perspectives behind this emergent technology. Please follow the link below:

  1. Hi Wendy,

    I see your tetrad foresees technology memory devices getting as small has a pen head. Do you see the technology extending itself to include other features such smell and voice command?
    I see this as expanding more options to users that will allow users to incorporate additional sensory options.

  2. Wendy,

    Great Post! Your introduction of the background and brief history of photography and cameras is enlightening.
    I see your tetrad is saved on slideshare.net. I have not used this website. Did you post your tetrad as a word processing document or did you have to convert it to an image file?

    Thank you,
    LeAnn :-)

  4. Wendy,

    I enjoyed your post and the introduction as well. I like the idea you presented about memory devices the size of a pen head. I too believe that the day is coming when we will see this. Great post! Have a great holiday!

  5. Wendy,

    Great post, I agree that in the near future that the memory cards will get smaller as well as have more memory. I liked the analogy to the television, they used this technology to invent the digital picture frame.
