The
images in this figure compare the results of photographing a
brain section on 35 mm Kodachrome film and processing through
Photo CD, with those from directly scanning the tissue on the
La Cie desktop Silverscanner II.
The original Photo CD image was captured by photographing on
Kodachrome 35 mm film using our specially designed slide holder
and illuminator, and a 80 mm Leitz Summar Macro lens on a Pentax
35 mm SLR camera with bellows extension for the lens.
The Photo CD image is from the high resolution Photo CD file
(1536 x 1024 pixels, 4 Mb); that from the scanner was scanned
at 400 pixels per inch (ppi) (2400 x 3200 pixels, 3 Mb). Both
images were edited in Adobe Photoshop, assembled into the composite
image.
The tissue is a horizontal section stained for cell bodies (Thionine
stain, Nissl method).
For printing, the composite image was then resized in Photoshop
to 200 ppi and 8 Mb. Excellent prints were then produced on
the Kodak XL 7700 dye sublimation printer, by DLM Imaging, Madison,
WI.
