PLAYING WITH THE COLOR AND IMAGEWritten by Blur Loterina
Does your image appear good on screen, but looks blurred, jagged or fuzzy when you print it?To clearly see difference of quality of image on screen and on print, take an image from internet. Zoom it out or make it larger. Can you see how series of little squares appear on image? Try to print it and you’ll see that color will fade. There will be a change in resolution. Resolution is, basically, sharpness or crispness of an image. When an image is shrunk, color looks lively. When you blow it or enlarge it, color will fade and image will look unclear. Resolution is defined as number of pixels contained in monitor. Pixel, from words “picture element”, is basic unit of programmable color in a computer image. The resolution is measured by number of dots per inch (dpi), which is equal to numbers of squares of color in an inch. A standard resolution for an image should be 300dpi and 400dpi for images containing text. The resolution of an image is inversely proportional to size of image. In other words, when you increase size of image resolution decreases, and vice versa. For example, if you enlarge an image, size, of course, increases. But quality or sharpness of image decreases, giving you a blurred image.
