Digital camera(old article)
Things are moving fast this day, so as the camera. Decades ago we use film camera and now we use digital camera. So what is the different and what so special about the so call digital camera? Digital camera basically does not use film to take a photo. It uses sensors which convert light to electrical signals which then convert again to produce photo in the form of digital storage. Secondly, you can preview the photo you took infinite times and you can delete the photo just by the mean of a click of a button. Unlike film camera you cannot delete or preview the photo you took.

When buying a digital camera you will notice the word "pixel" or "megapixel". That is the resolution for the digital camera or the numbers of tiny light sensitive sensors in the digital camera. The higher the mp the higher the better the quality of the photo you take. But it is also the main disadvantage of digital camera because it will never outdo a film camera in term of resolution. A film contain trillion of light sensitive molecues which then turn colour to form picture. That is why some photographer still prefer film camera. As time goes by, companies are keeping on develope higher resolution and more compact digital camera.The greatest advantage of digital camera is when it comes to movies production. During those day without digital technology they use tons of film just to complete one movie because there are a lot of "NG" and cuts. But now they can simply trim the scene that are not perfect or NG.
Ten years ago when digital camera is not as popular as it is now we use film to take photos. We usually buy two or three roll of films during vacation. A standard film contain 36 shots and we bought three. It will cost us about $7 !!! just to buy that three roll of film. If we went for vacation more than 30 times that will mean that we spent about $210 for film. Now since digital camera is digital it uses memory card or stick which can be used indefinite times over and over again. Some photographer use digital camera because of this reason.(picutures shown are samples only)
