Digital Images - PC

Image Sizes and Resolution

• Image Resolution describes how much detail is in a picture. In digital images it is often described as the number of pixels, or "dots", that make up an image. For instance a camera that takes pictures that are 4000 pixels wide by 3000 pixels tall will take pictures containing 12,000,000 pixels or 12 megapixels. An image that is 1200 pixels in width and 800 pixels in height has a total of 960,000 pixels or just under 1 megapixel.
• Resolution can also refer to spatial resolution, or how closely spaced the infomation is that makes up a picture. With digital images, this is often measured in pixels per inch or ppi. A computer monitor can usually resovle images with a density of 72 to 100 pixels per inch.  When printing high quality photographs on good photo paper, 300 pixels per inch will make the image appear sharper (assuming the original image was of high quality). 150 pixels is a good compromise for printing snapshots.
  
• Image file size in kilobytes or megabytes indicates how much storage space an image will require on a computer or digital media such as a storage card. It also affects how long it will take a fileto upload or download from the web. The file size depends on image format, and whether it is compressed or not, as well as on the pixel domensions. If the format and compression are equal, an image that is 800 pixels by 600 pixels will be 1/4 the size of an image that is 1600 by 1200 pixels.
