P45 Scanning Sensor

Specifications

For its overhead studio camera work Libraries Without Walls commonly employes a Kodak full frame CCD scanning sensor. The scanning element is manufactured on one unified chip. This means that no internal stitching or boundary areas exist inside the dimensions of the sensor's image area. The resulting digital back is identified as a 39 megapixel digital capture sensor. We mount the P45 onto a Mamiya 645 camera body for studio and in situ work.
