HABS photographers Fuji-Acros vs. Tmax
Just found out from Fuji that the Acros 100 4x5 quickloads are not on a polyester base and therefore do not qualify for the most stringent Library of Congress archival standards (500 years). Maybe this is old news to HABS-HAER photographers, but I couldn't find it anywhere. I was hoping to use the ACROS quickloads for a couple of projects. looks like i'll be shooting the TMAX readyloads (on Estar thick base).
Here is the response from FUJI:
Dear Mr. Schafer,
Thank you for contacting FUJIFILM, USA's Helpdesk Center. Please allow
us to assist you.
Acros 4x5 black & white quickload film is a cellulose triacelate base.
this is good to know, thanks!
i never submit other than tmax and occasionally plus x ..
knowing what is not allowed helps,
at least now i know ilford is still good
good luck with your project!
Maybe since Efke and Rollei 's 120 films are on a polyester base they will be acceptable for some HABS-HAER work? Sorta kidding!
plz explain HABS-HAER
habs/haer is the historic american building survey / historic american engineering record.
in the united states if a property is 50 years old, possesses historic
significance a red flag goes up if there is a state / federally planned,
designed or paid for project ( highway projects too ). there is a review
process called section 106 review, which is the historic preservation part of
the environmental assessment. if a property has enough significance
the government asks for a detailed written report, 4x5, 5x7 or 8x10 format
negatives and contact prints ( all archival &C ) and sometimes measured\drawings.
these are all submitted to the state historic preservation office ( shpo )
reviewed and sent to the habs office and then off to the federal archives.
over the years lots and lots of things have been documented from bridges
to greenhouses. and over the years the federal program has asked for only
"stuff" of significance on a national scale ( the best of the best sometimes ),
so ... if a property has local significance, the states record it to their own
standards. which are sometimes exactly like the federal government's, and
sometimes are not quite the same.

just to continue with John's assessment....this (HABS) was created back in FDR's administration (1930's) to put people back to work, along with architects, engineers, craftspeople, etc. HAER was created later and now HALS (?) for landscapes is the newest.

The Fujifilm USA website does not have the datasheet for Acros sheet film, only the datasheet for Acros roll film, which is, of course, acetate. The only sense I can make of this is that the Fujifilm USA helpdesk staff simply reached for the nearest data sheet, read "cellulose triacetate", and didn't know enough to understand that sheet films are almost always on a different base.
I suspect Fujifilm USA is wrong; its Web site provides no technical information whatsoever on sheet sizes of Acros. Based on my handling of Acros sheets, they appear to be coated on polyester. That conclusion may be supported by this data sheet on Fuji Japan's Web site:

If I'm correct, you can happily go on using Acros.

Oren posted while I was composing. Glad a Japanese speaker could verify my suspicion.
thnx for the explanation John
an interesting concept
a further question if i may, does this process save the subject from demolition, or is it a record of what is, or may be, lost?
