Introduction: DGtal Digital photography is a form of photography that utilizes digital technology to make images of subjects. Until the advent

of

such

technology,

photography

used

photographic film to create images which could be made visible

by

photographic processing.

By

contrast,

digital photographs can be displayed, printed, stored, manipulated, transmitted, and archived using digital and computer techniques, without chemical processing.

Digital Camera Overview

Why Digital Photography? 

Advantage over film cameras  Immediate

feedback / results  Don’t need to develop film  Ease of image manipulation 

Add interest to your web site  Publicize

and document library events  Pictures are worth a thousand words 

Provide material for library displays

Overview of Digital Cameras     

Lens types Case sizes Pixel depth Zoom power Storage media types  Older

memory formats  Newer memory formats  Alternative memory formats

Pixel Depth 

Why would you want more pixels? 3

megapixels  4 megapixels  5 megapixels  Foveon technology 3.4  Three

layers to each pixel  Equivalent to 10 megapixels

Traditional photography 

Traditional black & white photography, as practiced in a wet darkroom, is fast becoming a lost art. Even those commercial photographers who might prefer to work with film are limited by their clients' and art directors' demands.

Meanwhile, digital becomes ever more pervasive as it advances technologically while at the same time becoming easier to use.

Advantages  

1. Lesser cost One of the advantages that digital cameras provide is the fact that it is largely practical and convenient. There is lesser cost in the long run as one need not buy films anymore and will need not develop the pictures the old fashion way. They would only need to charge the batteries, get a reasonably large memory stick and they are good to go.

2. Better storage Photographers can now store the pictures that they have taken in their computers and in their cds, allowing them to use the memory stick over and over again. There is no more need to store rolls of film and worry that they might disintegrate.

3. Trial and Error Another convenience that digital cameras provide is the fact that one can actually view the photos right after taking it and have the option of erasing it when it is not good. This, according to experts, spoils photographers. Because they can do a take over and over again, they don’t learn the discipline of planning for their shot before actually pressing the button.

Disadvantages  

1. Need for Computer literacy Similar to film photography where you need to be also familiar with working in the dark room, one needs to have a modicum of computer skills. Not only will you be storing your photographs in the computer, operating the camera is like operating a small computer. You really have to be computer literate in order to maximize the functions of your camera.

2. Artistry is lost There are some that argue that artistry and spontaneity is lost when using a digital camera because photographers do not shoot using various effects. For instance, some would not bother to blur the background anymore because they can fix the photo in Photoshop and other graphic programs. One can do a number of things with the computer, erase flaws, fix red eyes and sharpen some features
