HDR Photography

positive slide - 2.4 - 1:256
color negative - 3.6 - 1:4096
When digitising photographic material with a scanner, the device has to be able to capture the whole dynamic range of the original, or else details get lost. The manufacturer's declarations concerning the dynamic range of flatbed and film scanners are often slightly inaccurate and exaggerated. Multi-Exposure records an original's maximum dynamic range by performing a double scan with an increased exposure time of the second scan. This procedure captures the light image area's details in the first pass and the shadow details in the second. Afterwards an algorithm calculates the final scan.
