Image Master Files

From May 2005 through September 2008 a Canon EOS-1Ds Mark II (16.7 Megapixel) camera mounted on a Graz model camera table was used for manuscript photography. In October 2008, the photography unit upgraded to two Hasselblad H3DII31 (31 Megapixel) cameras, each with its own camera table. The proprietary RAW files are converted into TIFF format files. These image master files are archived in three copies at different locations. The uncompressed TIFF files (Canon: ~47 MB; Hasselblad: ~100 MB) provide all necessary data for color management. TIFF files for reproductions may be ordered from the participating libraries (see Contact – library or collection). For internet use, images have been converted into JPEG files at five separate resolutions (max. 3 MB) and minimally processed to improve legibility.
