Introduction
They say, a picture says a thousand words, and when it comes to journalism, which is often a war of words, images are powerful and deadly weapons for sure.

Not only photographs, but even video clippings have become an integral part of photojournalism these days, taking into consideration of the diminishing line between print and electronic media.

Introduction
Digital or Film, which photography is better; this question is yet to have a definite answer. Lot of discussions, brainstorming, arguments have been going on, but like who came first; Chicken or Egg, this has no ending. I am not being prejudiced in saying that the R&D in digital is quite promising than film photography. Film photography has its own unbeatable advantages though.

Synopsis
Photography as such is a very vast topic to cover in a few pages. So this first write up will be a very generic one and further particular details will be dealt with later one at a time.

Photography, the word comprises of two parts; Photo (means light) and graphics (means to write or to draw). So Photography is to write or draw with light. By dictionary definition it means - the process of producing images of objects on photosensitive surfaces. But I can define it in many other ways. Photography is a form of art, it is a way to capture memories, it is a medium for data storage, it is a form of expression - a medium to propagate one's thought.
