Considering Megapixel and Resolution when Buying a Camera

When buying a new digital camera, there are lots of different factors that you will need to consider. The most important factors to bear in mind will be the number of megapixels and the resolution of the camera.

Digital Photographs

All digital images are made up of a series of different colored dots which are positioned very closely to one another; these dots are known as pixels. The resolution of the photograph will depend on the number of pixels which make up the image. With digital photographs, the resolution or the number of pixels can be affected in two ways. The first will be when you take your photo, and the second will be when you come to reproduce the photo. Throughout the rest of this article, we're looking at the importance of the resolution when choosing a camera.

What Is a Megapixel?

A megapixel is 1 million pixels and this refers to the number of pixels used to recreate the image in a digital format. Prior to multi-megapixel cameras, digital photography was always seen as the underdog to 35mm film cameras. The CCD is the sensor inside your camera which is responsible for converting the light into electrical signals; it is the resolution of this sensor which will determine the Megapixel rating of your camera.

How Many Megapixels Are Needed?

Megapixels are normally seen as the most important thing when choosing a digital camera, however, this shouldn't always be the case. The number of megapixels your camera has will not be the only thing which determines the quality of photos that it can take. A camera with a higher resolution will be able to take clearer and higher quality photos, however, this may be wasted on most people. If you are only printing out letter sized prints, for example, then a 4MP camera will probably be sufficient.

The higher the resolution of the camera, the more expensive it will be. This means that you should think carefully to ensure that your money goes as far as it possibly can.


The higher the number of megapixels your camera has, the bigger the size of the image that it will create. This is an important consideration because you will end up filling your memory card up much quicker. A 1GB memory card might seem huge at the time, however, if you start using it with a 12 Megapixel camera, then you will quickly fill the card up.

Just because you buy a high resolution digital camera, it doesn't mean that you always have to shoot in the highest resolution. All cameras can be adjusted to shoot at different qualities, which is very useful if you want to save more space, or simply want to take photos for the Internet.

Don't Concentrate on Megapixels

Although megapixels seem like a very important thing to consider when choosing a new digital camera, it's not the only feature you should be interested in. You must also consider the quality of the camera, the type of memory cards used, flash and shooting modes. The Megapixel and resolution really aren't everything.
