Does resolution and file size make a difference?

View our sample below to get an idea of the difference between resolution and the resulting files sizes.  When looking at the page section below, examine the three different parts of the image.  Look at the line art (orange bamboo), the type, and the photograph (halftone).

The sample below is only a portion of a page and the file sizes listed below each image are for this sample only.  The entire page when scanned in as a tiff was:

-  200 dpi - 7.28 Mb
-  300 dpi - 16.4 Mb
-  600 dpi - 65.6 Mb

For our own yearbook projects we scan in at 600 dpi tiff.  Then save the images as 300 dpi tiff's so that we can fit a yearbook on only one or two CDs.  For web pages we save the 600 dpi tiffs as 300 dpi jpeg's, 800 - 1000 pixels wide.  If you notice below in the bottom row, it is hard to tell the difference between the 600 and 300 dpi jpeg's.

What resolution and file type you select is up to you.
