John, that only applies for pix that will be printed by photo offset, and
relates to the line screen used to create the halftones. For material
printed at a screen of around 150 lpi (magazine quality) you would indeed
scan at 300dpi. This does not apply for the web as the max you can see on
most monitors is 72 dpi.
