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???)
shAf :o)
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
interchangeably?
