Let’s say we have a digital image that is 12 00x1800 pixels (dots) and 4圆 inches in size. The DPI of a digital image is calculated by dividing the total number of dots wide by the total number of inches wide OR by calculating the total number of dots high by the total number of inches high. People regularly discuss digital images in terms of DPI, which stands for Dots Per Inch. So, unless you resample (which means you artificially alter the pixel dimensions in a photo editing program) or crop the image, your image will always be 1200x1800 pixels. That means our digital image is 1200 dots high by 1800 dots wide. For example, let’s say we have a digital image that is 1200x1800 pixels (dots). The total pixel dimensions of an image will tell you how many total pixels (dots) the image is made up of. There are three different ways to describe a digital image’s resolution that essentially mean the same thing: And, the mor e dots a digital image has, the clearer the image, which is why you want to use high resolution (lots of dots) images to make Photographic Prints and Fine Art Prints. Digital images are made up of square -shaped dots (pixels). the resolution of the image dows not changes when its DPI value is changed. The DPI (dots per inch) of an image is simply metadata embedded inside the image header. This number is calcul ated using your digital image’s pixel dimensions and digital image size. DPI of digital image: DPI means Dots Per Inch.
