Scanning
Pictures and Documents
Resolution
= Quality
In
scanning, the resolution of
the scan determines the quality
of the picture and is measured
in 'dots per inch' or dpi. The
higher the quality / resolution
the bigger the file size.
Low
resolution or poorly scanned
images in many cases won't be
usable or will degrade when
enlarged enough to try to identify
faces or details in the pictures.
A
group picture scanned at a low
72 dpi resolution may be too
blurred when enlarged to see
the faces in the picture clearly.
The
preferred resolution for scanning
is at a medium or 300 dpi resolution.
The resulting file size will
be around 500k to 1mb +/- and
will be small enough in file
size to email without too much
trouble, time or inconvienence.
Scans
with file sizes in the range
of 300k or more are fine most
the time depending on the content
of the picture but if your scan
results in a file size of 100k
or less then it will probably
be too small in physical size
and low of a quality to use
because it can't be enlarged
without it becomming too blurred
to see anything in the picture.
If
you have a lot and need help
scanning let me know. You can
send it to me in the mail and
I'll scan it and send it back.
You
can also go to any KINKOS, FEDEX
or mailbox type store and get
your items scanned there and
then given back to you digitized
on a low cost storage device
small enough to keep in your
pocket.
To
learn about these, go to any
office supply store and ask
to see the 'thumb drives' or
'portable storage drives' or
something like that. They're
priced at about $10 for a good
quiality one that has 4 gigabytes
or more of storage, which is
enough for several books.
Be
careful you don't keep everything
you want to protect on one of
these without backing it up
on another back up storage drive
as they can become damaged and
suffer from the same file corruption
problems experienced with any
other storage drive used. |
