Hello everyone,

A few months ago I posted a message to this list asking for advice on = scanning large panorama negatives. I received several very good = responses, and now I'm pleased to show the results. You may recall that = these film negatives were large, one even up to 90 inches long and, and = that we were having trouble figuring out how to scan them, as well as = how to stitch the scans together. =20

Although some people recommended a camera, we didn't have a big or = bright enough light box, and the lower resolution combined with the = prospects of stitching images that may have suffered from lens curvature =
(yes, even with Hasselblad lenses) was enough to make our heads hurt. = We ended up using our Creo-Scitex Eversmart Jazz+ flatbed scanners =
(slightly modified) and fed the negatives across the shorter dimension, = so we got roughly 11-12 inches per scan. We scanned at 800 ppi, and the = resulting stitched TIFF files range from 150Mb - 400Mb. Once stitched, = the TIFF files were re-sized to JPEGs measuring 600 pixels in height x = the proportional length for presentation on the Web.

The stitching advice we followed came from Mark Shelstad, Associate = Archivist at the University of Wyoming, who suggested that we use the =
$64 Panavue ImageAssembler software to stitch individual scans together. =
It has worked very well.

The resulting website may be viewed at = http://www.lib.utah.edu/digital/digcol.html =20 Click on the "Shipler Commercial Photographers Collection"=20 Click on the "Search" link in the left column. =20 The search page has a drop down search box at the bottom called "Search = by Series." =20 Choose "Series P: Panoramas" and click "Go"

A direct link to the search page is = http://history.utah.gov/Photos/C275/indexform.htm

Currently there are nearly 60 panorama negatives, and within the next = few months the total will reach 250. In general, the shorter the = thumbnail images appear (in the height dimension) the longer the = panoramas will be. This project is a collaboration with the Utah State = Historical Society, and is part of a larger glass plate negative = photograph collection. We do the scanning, and the Historical Society = applies metadata and upload the images to our server. We are using = CONTENTdm for our image management/presentation software.

I hope you enjoy the images - they are really quite wonderful. Thanks = to everyone who suggested strategies for handling these enormous = negatives. I would appreciate comments/criticisms, and am happy to = answer any questions.
