Megapixels = Megabullshit !!!!

Mr Raj works in a bank and comes from a lower middle class conservative family. He wants to buy a new camera to keep those priceless memories. He decides to got a show room and buy him self the latest one. As soon as he walks into the showroom he is greeted by several advertisements and the only thing that catches his attention are the large fonts saying “megapixel”. After being bombarded by the Ads he walks into the showroom.

Raj - Hi I am looking for a camera.
Saleman - Yes, here is the canon camera, and it is 10.3 megapixel, with blah blah
Here is the Nikon camera with 13.4 megapixel .

Most ordinary people need a basic point to shoot camera, as their need is only to click basic photos. The question is does Mr Raj really need a 10 megapixel camera to take a simple snap of his family in front of taj mahal.

For all you camera lovers here a myth that is certainly the biggest rip-off, often used by camera manufacturing companies, retailers and salesman. The first thing in a TV commercial on you latest camera, the first words by your friendly yet sly salesman are “megapixel”

This trick is used by salesman and camera manufacturers to make you feel as if your current camera is inadequate and needs to be replaced even if the new cameras each year are only slightly better.


Whats a pixel ?

A photo is made up of little dots called pixels. Pixel stands for PICture ELement. Put enough of them together and you have a picture. They are arranged horizontally and vertically. Get close enough to your computer screen (or use a magnifier) and you'll see them.

Image Resolution

Resolution is the number of pixels you have counted horizontally or vertically of a photo. Most cameras today have between 2,048 and 4,500 pixels horizontally. A 3 MP cameras have 2,048 pixels horizontally and 14 MP cameras have 4,500 pixels. They have fewer pixels vertically since the images aren't as tall as they are wide.
That's not much of a difference, is it ?
Unless you are planning to print a billboard of your photos you can make do with a 5 megapixel camera.

What matters in you camera ?

Lens – The lens is the eye of the camera, quality of the lens is what decides the sharpness of the image formed on the CCD final, thus decides outcome of the photo. You only see the values of this in a digital SLR (single lens reflex) camera, where you can change the lenses. Same camera, different lens, and the pictures can improve vastly.
CCD – It is Like the engine of a car, the CCD sensor in a digital camera acts as the primary tool to capture an image. In its most elementary form, the CCD sensor is like the camera's "electronic eye": collecting light and converting it to charge, and subsequently emitting the signal that results in a digital image.


Next time you walk into a showroom to buy a camera you know if the sales man keeps rattling megapixel, just shut him up.

If you good friend cays he has the latest 8 megapixel camera phone, and you only have the good old 3 megapixel camera just click the same picture and you will see the difference.
Try this out friends.
Conclusion – Megapixel = Big bullshit story
