Re: filmscanners: Archiving Photos (a little off-topic)



Hi, Tomasz:

I *thought* there might be others out there with the same type of project. 
:-)

AFAICT, the programme you propose is the most truly "archival" way to 
procede (although the most bit- and storage-space intensive). It has the 
added benefit of forward-flexibility; that is to say, when DVD recording 
becomes widely available, or a new storage medium comes on the scene, the 
pictures can be transfered to the new media easily. I might, under those 
circumstances, be tempted to *up* the dpi on 5x7s to 5-600dpi. One never 
knows, and apparently you're not working with storage/size constraints. I 
*would* suggest that you use triple-redundancy--that is, record at least 3 
of every CD and store them in different locations, none of them hot, and not 
all of them in the same building.

As for 16-bit vs. 8-bit recording for B/W prints, there's little to gain 
*except* in the few that have very close values in some areas (and you 
*will* find a few, unexpectedly). Those areas may, on rare occassions, bite 
you on the arse, so to speak. :-) Otherwise, 16-bit takes up twice the space 
of 8-bit B/W pictures, and 8-bit are pretty good. It's your call.

The red cast in old color photos is not limited to Poland. It's more likely 
from the fugitive yellow and blue analine dyes used to make the print than 
the paper (although acid paper will often do the same thing). It's a b*tch 
to correct, because there's so little yellow and cyan left to record. 
Vuescan's "Faded Image" often helps, but I don't know if VS works with the 
Agfa Arcus 1200. My advice is to pick the absolute *worst* example you can 
find and spend several hours retouching it. You may not be able to "bring it 
all the way back," but you'll learn a lot. I've found the color correction 
tools in Photoshop to be the most helpful, but Corel's are good, too. I 
generally leave the histogram where it is, in that I think anything beyond 
that is "interpolated" (i.e. added by the computer to where it doesn't 
exist), but I could be wrong.

Anyway, good luck, and if you run into trouble feel free to contact me--not 
that I can help every time, but I can try.

Best regards--LRA
