After
researching options available for creating and maintaining a widely-accessible
virtual collection, Luna
Imaging’s Insight® browsing software was selected
as the most appropriate way to present the A. D. White Architectural
Photographs over the Internet. To date, 1260 of the 13,000
photographs have been captured digitally for the virtual collection
by Rhea Garen and David
Jones, staff members of the Cornell
Institute for Digital Collections. More digital images are being
added as they are digitized and processed, according to a regular
schedule. Users can now view and search through images, create virtual
exhibitions and conduct efficient research from their own desks,
wherever they may reside. In the near future, the Insight®
browser will permit cross-collection searching, thus allowing users
to compare A. D. White Architectural Photographs and associated
cataloguing data with images in other collections across the country
and the world. For information about copyright issues and securing
permission to publish digital reproductions of images from the A.
D. White Architectural Photographs Collection, please consult our

Page.
Every image
in the collection is captured on a PowerPhase
One digital camera scanning back on a ZBE
Satellite copy stand at 600 dpi, and in 36-bit color (interpolated
down to 24-bit color images). The capture generates an .TIF format
image file of 80 to 140 megabytes in size. A cropped, color-corrected
image is then made from this rich master file, and is in turn used
to create .JPEG and MrSID (Multiresolution Seamless Image Database)
derivatives. MrSID is a next-generation image file format from LizardTech
that reduces the size of high-resolution images to less than 3%
of their original size while maintaining the quality and integrity
of the original. Master files are archived on CD ROM. Finally, derivatives
images are made available through Luna Insight.
