Hi Peter,
ahh, flatbeds, well let's try to stir up some conversation here!
Ok, first of all, I recently read an article on flatbeds in a local computer
paper, they did a few tests with single pass, and 3 pass scanners,
first they say: NEVER BUY ANYTHING BUT… A SINGLE PASS FLATBED SCANNER
they found that each pass didn't exactly scan exactly the same, therefore the
image was not as crisp as the single pass scanner, also it takes 3 times as
long! also colour reproduction was worse with a 3 pass scanner.
Here, the price of a 3 pass scanner is 599$ – Relisys (model 2400)
1 pass scanner .. 899$ – Relisys (model 2412)
Also with a 1 pass scanner doing a colour preview is a lot faster.
(I'm taking this from a magazine).
Now, even the more expensive scanner at 899$ is still only at 300 DPI,
and lots of people on local bbses have told me to steer clear, as this is too
low for doing quality scans.
That new HP scans at 600 dpi, and I saw it work, very nice results. The thing
I want to know, is.. will it do scans like the ones you see of calender girls
in .jpg form, or .gif form ? ones you find on your local bbses. I find these
are very nicely scanned and wonder if they could have been done with a 600 dpi
machine. Anyway, if you have more questions, I'll try to answer, and…perhaps
anyone else reading this could help us out.
by the way, you are right, the files will get bigger with 600 dpi, but remember
that after scanning you'll probabally crop the images anyway, (some of them)
thus reducing those nasty little bytes that add up so fast!
With the flatbed you are using … what is the dpi that you are scanning at ? I
mean the optical dpi, or real scanning dpi the machine says ?
just curious,
…
ok, bye for now
