Buying a Camera – How Many Megapixels Do I Need?

When shopping for a new digital camera, there are lots of various things that you will need to look at. The most critical specifications to remember will be the amount of megapixels in the camera.

Digital Pictures

All digital pictures are made up of a series of tiny colored dots which are put very closely to each other; these dots are called pixels. The result photograph's quality and/or resolution will depend on the number of pixels which form up the image.

With digital pictures, the resolution or the number of pixels can be influenced with two methods. The first is when you shoot the photo, and the second is when you "develop" the photo on the computer. In the course of this article, we're exploring the relevance of the resolution when selecting a camera.

What Is a Megapixel?

A megapixel is 1 million pixels and it indicates the number of pixels involved to construct the picture in a digital format. The CCD (charge-coupled device) is the sensor inside your camera which is responsible for converting the picture it grabs into digital value, it is the resolution of this sensor that establishes the Megapixels in the camera.

How Many Megapixels Do i Need?

Megapixels are generally viewed as the most significant factor when purchasing a camera, even so, this should not always be that way. The amount of megapixels your camera has is certainly not the only thing that shows the quality of pictures it makes. A camera with a greater resolution will be able to take sharper and better quality pictures, yet, this may be waste of money for most people.

If you want to print out your photos and say, standard letter sized, then a 8 megapixel camera will very much suit for the job. Remember, a higher megapixel camera is useful only if you want to make very large prints. The more megapixels the camera has, the more pricey it will be. Think about your budget and think this through.


Higher megapixels photos take up much more memory space than the average megapixel photos. With too small memory card, you may result in filling your memory card up very quickly. A memory card under 2GB should not be even considered, may look massive at the time, yet, if you have space of 2 gigabytes in a 16 Megapixel camera, then you will run out of space very soon.

Buying a high megapixel digital camera doesn't immediately mean that you always have to take pictures with the maximum resolution. All cameras can be arranged to shoot at a lower megapixel rate, just to save your memory space, or maybe when you want to take photos for the web.

Don't Focus on Megapixels Too Much

While megapixels sound like a very significant detail to look at when purchasing a new digital camera, it's not the only feature you should be curious about.

You must also consider the quality and the type of the camera, optical zoom, shooting modes, battery, and perhaps the newest features like WiFi or GPS.
