|         However, the math does not agree with the filesize you mention!!

|         (5" X 385ppi) X (7" X 385ppi) X 3 RGB channels is not equal to
5Mb!!
| ... more rather, ~15Mb (no wonder you are confused???)

| I checked a specific file and came up with this data:
| 2794 x 1884 pixels; 7.257 x 4.884 inches (print size); 5,146 KB; 385 ppi
| (PhotoShop)
| It is interesting that VuePrint Pro_32 refers to 385 dpi rather than ppi.
| In scanning and printing terminology can we use the terms dpi and ppi
