Should You Go Digital? |
|
By Jim Zurbrugg
Digital photography not only means getting photographs immediately, but also sharing them easily and inexpensively with a vast network of people. However, to the traditionalist digital photography means cheapening the time-honored art of photography. What are the pros and cons of digital photography, and how do traditional and digital photography differ?
How the image is captured is the difference between digital and traditional photography. Digital photography cameras act more like computers than traditional cameras. They utilize thousands (or millions) of small squares called pixels to create an image, rather than an image being processed onto a piece of film. Each pixel stores information about the contents of that particular pixel, such as color, brightness and contrast.
Most digital photography cameras have an LCD screen on the back where the photographer can see the picture immediately. This is the biggest plus of digital photography because you are able to see the photo immediately. It also eliminates film and developing costs because you can download the photo to either a computer or a digital picture printer.

A camcorder is no longer just a camcorder. In fact, most models are now known as digital camcorders and are capable of not only capturing audio and video, but still images as well. A digital camcorder is popular, in part, because of it’s versatility in being able to capture audio and video while doubling as a digital camera. Conceivably, owners could use these products to capture family moments on film and use the digital camera aspect to photograph products for placement on eBay. While this is merely an example, the versatility of a digital camcorder is undeniable.
A digital camcorder delivers improved audio and video quality as opposed to older models, which recorded video in analog form. This earlier form of video storage, while effective, proved to lose quality with age and begin to show a grainy texture. These deteriorating effects do not occur with a digital camcorder because, with these devices, it is literally an ‘all or nothing’ effect. Either the entire data, or none of it, is readable.
The earlier camcorder featured a VHS-compatible videotape whereas the digital camcorder often is accompanied by a connector, which is used to transfer the data to a computer or television. If the data is placed on a computer, it can be edited, converted and/or copied with the proper software. Many amateur filmmakers, in fact, use their computers and a ditigal camcorder to create their latest film.
