Epson 2450 Autoscan slides

Whle experimenting with my scanner last night, I found that using the
automatic scan on slides limits resolution to 1200 ppi. To get 2400, you
have to scan each slide manually.

Is this for real? Or, am I doing something wrong?

I think I recently read something in regard to this occurring when you are
in the most auto/"no user intervention mode" but that if you went into Home
or Professional modes (on the 3200 at least) you were then able to get the
full resolution. Sorry that I can remember things in more detail. Do you
have the latest version of the software drivers from the Epson support site?

Grubbing around in the help files, I found the following entry, seemingly
related to auto scanning (the Twain help is so pathetically laid out it's
not clear; I found this by searching on 'Film' after finding nothing for
slides and other obvious choices):
-----------------------------------------------------------
OK, this didn't come out nicely with cut and paste. So I've tweaked it a
bit and snipped stuff:
------------------------------------------------------------
Color Positive Film

When the scanned document is recognized as color positive film, the image is
scanned using following options.
<snip>
Input Resolution ... Output Resolution ... Output Size
Variable ...................300dpi ....................... 4 x 6 inches
The input resolution is determined by zooming ratio between source size and
output size to get the output resolution 300 dpi. The ration of length and
breadth of image is always kept.

See -- Epson knows better than you do what you want :-).
It's not so much they specify the resolution to scan, but assume your only
desire is to make an inkjet 4x6" print. Of course it would be too scary to
tell you this outright.

So it seems like yes, you have to do them 'manually' to get full resolution.
But why the heck would you buy a fancy-ass scanner like the 2450 and want to
do more than use it to make dinky snapshots, eh?

Classic! ;-)

300ppi is not even an optimum input resolution for Epson's desktop
inkjet printers, which resample everything to 720ppi. So the optimum
resolutions of the image for compatibility with their own printer range
should be either 720, 360 or 240ppi.

Epson left hand... can I introduce Epson right hand?

It's not so much that I object to their making this assumption. It's that
they hide it away so you may not even realize that's what it's doing. By
trying to be "user friendly" they in fact become user hostile to the
at-lest-slightly-more-sophisticated user who would have reason to buy the
2450.

But you are assuming that "auto" is short for automatic. As with most
software user interfaces these days, auto is an acronym:
A - Advanced
U - User
T - Torment
O - Operation
