A few scanning tips

Larry will confirm, these formuli relate to a single size of image. But in the real world, one minute you have a 2" wallet photo, the next a 14" wide roadmap. You will not successfully apply a general dimension or scan rate to disparate sizes.

    Digital Resolution The resolution of a digital photo are its pixels. The more pixels that cover a specific area, the greater the digital resolution. This is ppi in reverse, that is, the number of pixels that resolve a certain feature. For instance, say you take a picture of a 20 foot wide billboard.
