Abstract

Your digital photo comprises a certain number of dots in the x and y directions. What happens to the print image quality as you "stretch" those dots out to larger and larger pictures? (Note: This experiment studies the dots per inch in the image itself, not the number of dots per inch that is output by your printer.)
