2.6. Resolution, Color Mode and Color Adjustment

Resolution

PPI & DPI (Pixel per inch and Dots per inch respectively) are

the standard units for measuring image size. Resolution is
the number of pixels on a printed area of an image. The 1”

higher the resolution, the more pixels there are on the page,
the better the quality of the image. However, high resolution

increases the size of the file. The standard recommended
resolution for printed images is 150-300 dpi, for Web images

it is 72 dpi.
