Topic: Estimated Size of the Data Set I am looking to Archive
I did some Scan Tests and some 'figuring' to get a feel for the
size of the data set I am going to be coping with after scanning this
box. It looks like there are about 500 Photographs that are 'Useful'
in any Family, Genealogical, or Aesthetic, evaluation. The majority
are NON-Archival 3.5 x 5 'Machine' prints which are actively self-
destructing due to the nature of the underlying technologies. Some of
the most recent are 4x6's and a smattering of 5x7's and 8x10's round
out the group. Ooops - I didn't mention a random assortment of Wallet
Size prints.
I decided to err on the 'large side' and use a 'working assumption'
that the average image is a 4x6in size. This works out to 25mb when
scanned at 600 dpi and 100mb at 1200dpi (both at 24bit depth).
500 x 25mb = 12.5 gig
500 x 100mb = 50 gig
These figures came as a very happy shock to me. These figures don't
include the smaller greyscale scans of what ever 'photo backs' have
info on them, but the files will be much smaller and not agregate as
quickly and affect the final number appreciably.
I like The looks of these numbers a LOT. I am not as fearful now. I
can fit 16 gigs on 25 CDR's and a 100+ gigs on the same number of
DVDr's.
The problem is still kind of complex because my 'preliminary plan' is
ONE SET for Each of my Grandmother's TEN CHILDREN. That is 2500 discs!
OUCH.
** I have decided to Predominantly Scan at 600 dpi for those images of
low quality and 1200 dpi for those images of any meaningful resolution
or sharpness in the print. **
My Photographer's Heart makes undercutting the image files a "Future
Me" will receive from this project feel like an awful thing to do! :-)
I'll just take the 'hit' file size wise and cope with the effects it
has on the aggregate size of the file collection.
