Image resolution refers to the size of an image displayed on a computer monitor, not the physical dimensions in which the image is printed. The pixel dimensions of an image indicate its resolution. Many digital cameras allow you to change the image resolution. Therefore, before taking an image, you should first judge the quality of the image using the camera's highest quality setting. So if you want to take good quality photos, set your camera to the highest quality.
According to Julian Foster's article "Image Quality - An Explanation" published at www3.teleplex.net, a true high-resolution digital photo can range in size from 12 MB (for a 4 x 5 inch image) to 12 MB 70 MB (for double-page spreads). His CD-ROM photobooks currently on the market have files ranging in size from 500 KB to 22 MB. He added that image resolution, the amount of information in a digital file, is measured in dots per inch. Screen ruling, the density of lines of dots used to print continuous-tone photographs, is measured in lines per inch. Newspapers typically use 85 lpi coarse line screens. Self-release, 100-120 lpi. Glossy magazine and high quality offset lithography, 133-155 lpi.
Proper resolution is very important for good prints. And to achieve this, you should always remember some rules such as:
Text must be 400 dpi at final layout size. Images must be 300 dpi at the final layout size. The dimensions of resolution and size are inversely proportional to each other. Therefore, enlarging an image decreases resolution, and shrinking an image increases resolution. How the image was originally captured determines its resolution. Therefore, it determines the size you can print for crisp, crisp prints. Low-resolution images print with jagged edges and look blurry.
When choosing a print size for your image, you should choose a size that is appropriate for the resolution of the image you are providing. The size at which an image can be printed without loss of quality depends on the resolution of the image. Note that the higher the image resolution, the better the printed image quality.
Most digital cameras allow you to select a combination of resolution and quality in the settings menu. For the best print results, your digital camera should be set to the highest possible resolution and quality. Always remember that the higher the quality, the larger the image file. Guys, make sure your memory card has enough storage space!
