Advantages and Disadvantages of Digital Imagery

Advantages:

Speed of getting images-Digital images are instantly available for output to print or video tape, or save as an image file.
Uses of the image-Images can be actually inserted into numerous computer applications like printable documents or presentations
Ease of duplication-Just copy a computer file or print as often as you like
Cost savings -- no film/no developing The images are stored in computer memory or other digital storage.
Pictures are printed directly from a computer to a printer.
Control over images & quality software -Software allows images to be changed, cropped, compressed, etc.

Disadvantages

Quality of image -Few inexpensive digital cameras produce slide quality photographs, but most do produce standard VGA resolution
You do your own processing work- You can’t just drop it off and pick it up an hour later.
Cost of camera Cost of consumer digital cameras ranges from $100 to $3000.

Consider the hidden cost of using film:
If you purchase a "good" regular 35mm film camera, it will usually cost less than a "good" digital camera. But if you consider the cost of film and developing the cost of the camera increases with every roll of film taken. The only comparable cost with digital is the cost of batteries, and you can now get very good rechargeables inexpensively
