Since it's establishment
in 1939. the Central Laboratory for Photography, Microphotography and
Reprography is performing protective and safe shooting of archival material,
storaging of picture on diverseful carriers, as well as processing and
protecion of photographies. The development of shooting technics, the
medium for picture storaging and informatical technologiy has significantly
influenced on the work of the Laboratory. Besides the shooting and chemical
processing of filmed material in Laboratory, the archivical processing
of photographs and microfilms inside the photograph collection of the
Croatian State Archives, is also performed. Protecting shooting of the
conventional archival material is done by microfilming, photographing
and scanning.
The large amounts of archival material, cause of the durability
of carriers and suitable shooting technics, is microfilmed on 35 mm silver
halides reperforated film from which further safe copies are made by retaking
and copying. Considering the war circumstances at the beginning of the
1990's, the selection of the archival material for microfilming was completely
oriented on the most endangered archival material. From 1991. till 1997.
2 000 000 microfilm shots of registers of births, marriages and deaths
from the Republic of Croatia's teritory, was produced. Digital techic
of archival material filming, is applicable by using the digital component
on the back side of the camera, of surface scanner or, even, the special
scanner for micro forms. The Laboratory also provides services in filming
of the archival material for users, on black and white or colour film,
microfilm, paper, disc or discette.
After the processing, filmed microfilms are stored in
microfilms' library where, there are, today over 5 milion snapshots of
registers of birth, marriage and death, glagolitic records, map sites
and other material from the Croatian State Archives and other archives
in Croatia and abroad.
Photographs, with motives significant for croatian history,
that are kept in The Croatian State Archives, are processed and preserved
in photo library. The largest part, a sum of 700 000 photographs, is created
by the Photographic documentation agency which kept track of all relevant
events in Croatia and former Yugoslavia, in the period from 1939. till
1990. Other photographs were made from the first half of the 19th century
till today and they demand a special care because of the diversity of
the technics they were filmed with and made of.
Concerning the protection of the photo library in the
Laboratory, protective copying of negatives on flammable surface, colour
slides and negatives on glass is performed, as also the photographies
out of negatives on glass are being made; damaged negatives are being
recontructed and etc.
