Setting Resolution With Epson Scan

Under "Destination" in Epson Scan, there is a setting for Resolution.
Epson Help says this is output resolution, which is perfectly logical.
However, I've read some Websites & postings elsewhere, referring to
scanning with ES at 3000, 4000, etc., resolutions. These are input
resolutions, in my mind, but I don't know how that could be done with
ES, since the only resolution setting is for output resolution.

What am I not getting, here? ES has only one resolution setting & that
is for output, as far as I can tell.

Of course, scan resolution can be determined backward. For example, if
output resolution is set at 300 dpi and a scan of a 35-mm has a target
size of 8 x 10, and the resulting image is 2400 x 3000 pixels, then ES
is obviously scanning at about 3000 ppi.

Is there any way of telling ES to scan at a resolution higher than 3000

ppi without having to increase target size to obtain a higher scanning
resolution? My hunch is, you can't. I suppose that you could scan to
produce a higher target size, then in PS, specify an 8 x 10 size to
print at the resulting higher resolution. Somewhat roundabout, but then

simplicity has its complexities. : )

Go to the "scanners and cameras" tab in the control panel. Then click on
the icon for your scanner. In the properties tab, you will see the optical
resolution for your scanner.
Any other output resolution requires some kind of interpolation.

Cool tip! I never knew the data was located there.

I think you have almost answered your own question here. Set the target size
to 'Original' and the magnification to '100%'. Then your input resolution
*equals* your output resolution. As another poster in this thread has
indicated, you need to beware of interpolated resolutions. Therefore, select
values which are factors of your max resolution. e.g. if your scanner has a
max resolution of 3200, then 1600, 800, 400 etc should (although not
necessarily) be native optical. 300ppi definitely wouldn't be.
