Ever zoomed in close to a photo to find tiny squares of colors? Those are pixels. It’s a basic unit of programmable color on a computer display or in an image. What is a pixel? In short, the pixel is the smallest unit of information that makes up a picture-the more the better. This often occurs when the original pixels or points in an image are stretched beyond their original size.īefore I get into the zoom issue, let’s back up a minute and look at how pixels impact image quality. Pixelation is a term used to describe fuzziness in an image due to the visibility of individual pixels. Abusing the zoom function can cause pixelation.
Keep in mind, however, that smartphone cameras come with one major limitation - digital zoom. Today’s smartphone cameras have improved enough so that they are a good alternative for taking high-resolution images for including in a book, magazine article, or online blog. The eight to twelve megapixels in most smartphones are more than enough for capturing photographs that are the optimum resolution for print and digital publications. Having the right camera for documenting equipment and activities is important. Photos also help you capture the colors, life, and atmosphere of your latest adventure. Taking photographs while on the road is a great way to hold on to visual proof of a great vacation or an interesting find.
