Digital CameraDigital camera is a very important tool these days. People would always like to save their memories in the form of pictures that will last forever. People were amazed when the very first camera was introduced hundreds of years ago. At that time, the camera consisted of bulky and impractical components and was very difficult to use. In fact, it even took a while to develop the images on paper. But there are now digital cameras that are very easy to use and, thanks to their pocket size, you can take them anywhere. Using a digital camera has several advantages: very simple to use, easy to use, instant feedback; which means one can immediately review the captured images and erase any images they don't like. A real advantage of the digital camera is that one can easily share the photos with other people thanks to the high-speed Internet connection. Before the digital camera, you had to print photos, pay shipping, and wait for the photos to be delivered. Those days are over as it is now possible to share photos online in minutes. Introducing the Powershot S400, a genuine product only offered by Canon. So popular that it has many different websites discussing its features and advantages over other digital cameras. The first website is the Powershot S400 website (www.powershot.com/powershot2/s400), the second is megapixel.net (www.megapixel.net/reviews/canon-s400/s400-review.html) and the last but not least: DCRP Review: Canon PowerShot S400 Digital ELPH (http://www.dcresource.com/reviews/canon/powershot_s400-review/). Talking about the Powershot S400 (www.powershot.com/powershot2/s400). The website looks professional and is very good... middle of paper ...... about it. The website also looks good, but not as professional as the first one. The big plus of this website is the forum chat section where users can communicate with each other by sending messages in the context of the digital camera. The third website has the simplest appearance of the three. The two best features of this system are the active buyer's guide (these virtual sales assistants give the best product recommendations based on one's specific needs and uses) and the discussion forums which are very similar to the megapixel user forum . We can't say if one of the three is the best because they complement each other very well.
