By
leaving the dpi at 2700 or 4000, is the file size larger than it
would be at
72dpi?
Not really. What your are doing is creating an image with a certain
dimension, i.e. 450x300 pixels. Then you set the dpi to for instance 4000

Austin,
Like it or not, DPI tends to be the common usage in the everyday world even
if technically it is the wrong terminology and should in the case of
scanning be PPI. I think that you may be being a little picky here; but

Hi Ken,
2592x3888 pixels, 2720 dpi, 4x6inch, 22.7MB

I believe it is simply calculating the DPI. It's certainly easy enough to
do... What file format are you talking about, BTW?
The numbers you gave above don't seem to fit...did you make those numbers
If you are not scanning with VueScan, ignore this letter.
I am not scanning from VueScan, though I do have it and understand the
implications of RAW scan from it, as you explained. In Polaroid Insight
there is an option for a RAW scan at the scanners full bit depth. Is this
the same RAW scan

Gee Austin, thanks for that insight. I NEVER would have figured out what
Anthony was getting at without your clear, exacting, obsessive attention

No. DPI is just a number recorded in the file; it has no influence at all
on the file size.
Also, by leaving the dpi at 2700 or 4000
are you creating a higher quality graphic
file?
No.

Just changing the dpi number doesn't change

Sort of. An image file doesn't actually have a size in inches. However, if
you record a DPI setting in the file, and if a program reading the file

One of the reasons for the confusion is that
Photoshop (stupidly, in my opinion) insists
on changing the pixel dimensions when you change

Photoshop is designed to prepare images for print use as well as online use.

The DPI of the scan in the image file is set by the scanning software that
creates it. The Nikon scanners I use routinely set the DPI to the actual
DPI used to create the scan (usually 2700 or 4000, the two resolutions I
most often use).
Anthony,
The DPI setting of the file is just an information field,
Exactly what field is it, and in what file format are you talking about?
A few
programs look at the DPI setting when you select options like display at
actual print size or when you try to print a file.
Display actual

JPEG and TIFF both store horizontal and vertical dots per inch in their
headers. GIF and BMP don't. I haven't checked other formats, but I expect
any modern format do.
