When shooting photos, you can adjust the camera settings in order to shoot at a designed resolution of your need. A digital image is made up of tiny dots also called as pixels. Simply, more dots means more pixels means more resolution means better image quality. Therefore, if you intend to send photos through the Internet, you can shoot a lower resolution but if you want to print the photographs, you can always shoot at higher resolutions. Determining the amount of camera resolution you need will depend entirely upon the print size of the photo, such as a poster size or the standard photo print sizes, as such.

The terminology “Resolution” refers to the digital image size produced by the camera and is expressed generally in terms of “megapixels”. The total number of pixels captured by a camera is called as the camera’s resolution. For example, a camera that can capture 1600 x 1200 pixels goes on to produce images with a picture resolution of around 1.92 MP or megapixels and is generally referred to as a 2.0 MP camera for marketing purposes. Therefore, a 5MP digital camera would always give better picture quality than a 2 MP camera or a 3 MP camera, since it would amount to more number of pixels.

The advantage of having a digital camera with higher resolutions would mean that you would have more number of pixels to work with in terms of getting prints made. Thus, if you start with a high resolution image, lesser magnification is necessary for getting to the given print size. A printout can be produced from just about any image, but, the more you magnify, the more you degrade its quality. For recording images, each pixel goes on to build up tiny charges of electricity in response to light. Though digital cameras boast of high resolutions, you need to get the one that suits your needs most.
