A few scanning tips
As a review of the first part, hopefully these points were made clear.
|Properties of Printed Images||Properties of Video Images|
|Image size is measured in inches||Image size is measured in pixels|
|Image size does NOT vary with scanned resolution||Image size varies with scanned resolution|
|Image size is modified on paper by scaling||Image size is modified on screen by resampling|
|Image pixels are spaced on paper using specified scaled resolution||Image pixels are located at each screen pixel location, one for one|
|Several printer ink dots are used to represent color of one image pixel||One screen pixel location contains one image pixel, and can be of any RGB value|
