For its overhead studio camera work Libraries Without Walls alternately employs a Kodak P45 full frame CCD or a Leaf Aptus 75 full frame CCD scanning sensor. The Leaf Aptus 75 digital back is identified as a 35 megapixel digital capture sensor. We mount the Aptus 75 onto a Hasselblad camera body for studio and in situ work.
