Our
scanning and archiving services provide you with high
resolution
digital photos. We have two options for storing your high
resolution files, CD-Rom and Data DVD. We'll discuss these
two formats in more detail below. Along with your high
resolution files we can also provide you with a number
of other output
options that make having a digital photo collection fun
and easy to use. Our other output options include: DVD
Videos of your photos: Uploading
of your photos to leading "Photo Sharing" web
sites
where you can order real prints, calendars, and other photo
gifts, or share pictures with family and friends: JPEG

CD vs. Data
DVD for storage of your High Resolution Scans:
After scanning, your new digital photos need to be saved
to some type of digital media for storage purposes. We offer
two options for storage of your new digital images: CD and
Data DVD. Most of us know what a CD-Rom is but the term
Data DVD may be new to you. What is a Data DVD? A Data
DVD is not a DVD Video; it will not play in a set top DVD
player.
Data DVDs work just like a CD-Rom. They are a storage medium
for storing files just like a CD. The only difference is
they hold more information than a CD would. Data DVDs work
with computers like CD-Roms do. However your computer needs
to have a DVD-Rom disk drive to read our Data DVDs.
Ok, so which
is right for me?
The charts below compare the pro's and con's of each format.
We use Mitsui MAM-A Gold Archival quality CD-Rs and Taiyo
Yuden DVD-R media for our Data DVDs. Both of these are
high quality storage mediums that far exceed the quality
of media
you might find at your local Walmart. Please review the
charts below for a review of each format or click the

MAM-A's web site at www.mam-a.com

Pros

Pros
Cons
Estimated lifespan of 300 Years,
much longer than DVD-R's expected lifespan.
Estimated lifespan of 100 years.
DVD's are not expected to last as long as Archival
Quality CD-R media.
CD-R's only hold 650 MB of data.
Much less than DVD-R media.
DVD-R's hold 4,700 MB of data, a
little more than 7 times that of CD-R's.
Higher Order Cost: CD-R's hold fewer
photos than DVD-R's. More disks will be needed if
your placing a large order.
Lower Order Cost: Because DVD-R's
hold more photos you will need fewer disks when placing
a large scanning order.
CD's work with just about any computer
and don't require a DVD-Rom to be installed on your
system.
To use a DVD with your computer you
must have a DVD-Rom installed in your system.
Less Organized: Less photos per disk
means you may have to find the right disk to get
the photo you want.
More Organized: It's easier to find
the photo you're looking for because you'll have
fewer disks.
* Media Lifespans are based on manufacturer's
estimates. Digital Memories makes no guarantees
or warranties concerning media lifespan or longevity.
As you can see from the charts each format
has some benefits. If you want media that will last as long
as possible then Mitsui CD-R is the way to go. If you want
to be organized while keeping the cost of your order down
then Data DVD is the option for you. Please remember that
you will need a computer with a DVD-Rom to use our Data
DVDs.
How many photos
will fit on one disk?
This depends on the type of photo or film that is scanned,
the resolution the photo was scanned at, and the file format
the photo was saved to. We offer two file formats, TIFF
and JPEG. Click here to learn
more about TIFF & JPEG formats. The charts below
list the number of photos that may be stored on one CD or
Data DVD. The first chart is for 35mm slides or negatives.
The second chart is based on print scans of either 300dpi
or 600dpi organized by the size of the print scanned.
