What is HDR?

HDR, or High Dynamic Range, is a technique of combining multiple images at different
exposures to extend the overall dynamic range of an image as well as to improve the noise
performance in the image. The scanner performs HDR scanning in a two pass process. The
first pass is a scan at the normal exposure. The second pass is at a significantly higher
exposure to give more detail in the blacks. When the normal and high exposures are blended,
the result is the best of both at a higher bit depth. The second pass runs at a slower speed to
prevent blurring from the longer light source pulse durations required.
These images are scanned of the same frame to demonstrate the difference
between a standard scan (top) and an HDR scan (bottom). The HDR scan
exhibits less noise, more accurate colors and better shadow detail.
The high precision HDR gates and the image stabilizer align the initial scan and high exposure
scan with sub pixel accuracy using a high quality resize filter, which creates an HDR clip free of
alignment artifacts.
