Camera, heard of it from the time you are born or have used one since your childhood. Some have got used to it during different occasions like birthdays, school functions etc. As time has changed, so is technology.

Gone are the days when we used to insert a film roll & then get the roll developed, today is all digital. You can save the snap on your computer, USB etc and print them yourself. You have different types cameras with different features. There are handcams, mobile cams, web cams, spy cams etc.

Well today we have cameras on the roads,in shopping malls,schools etc. Some say they are good while others disapprove. Some say it is a invasion of privacy.We also have cameras which are placed in satellities thats how we can see the places on google map.Some countries use these satellitie cameras to spy on other countries. They are also night vision cameras.

The Military & secret agencies also have High-Fi cameras. Many people are purchasing spy camera specially women.The reason is because many of the men are cheating on their wives. You also have hidden camera in pen, breifcases etc. Journalist are using this type of gagets to catch corrupt ministers, for match-fixing, military deals etc.

There are also people who used hidden camera in ladies changing rooms & toilets. So ladies be aware. Traffic cops use high speed cameras to catch thoses who are speeding. Today all countries are having a centrallized control unit where they can see the whole country that is all the roads. London has the highest numbers of cameras in the world.

Shopping malls have installed cameras not only to catch shop lifters but also to provide security to others customers. Schools have put camera in the hall waysto monitor students whether it betocatch those studentsbunking classes or ragging etc.

There is a saying: " Seeing is Believing". but that's not always true. Camera are shot from one angle. So it if you have 4 camera's, each camera will have a different angle & so you see only one side of the story & not the other. This can be better understood when there is a live coverage of any event. A few years back there was a english movie "Vintage Point", those who have watched this movie would understand this concept better.

Cameras do have their advantages & dis-advantages, they are good as you can capture those special moments in our lives, some times they can save lifes of people, control traffic, catch culprits & also encourage people to have photo competition either on your digital camera or just a mobile camera.
