![]() ![]() Note the lack of detail in the highlights and shadow areas of this “raw scan” image. The image above marked “raw scan” shows the data of the primary scan, just cropped to show only the frame of interest (not the over-scanned areas) and then re-scaled to the same resolution of 960 x 720 px as the “release” frame. So in the end, for every film frame five different scans are taken, covering a large exposure range. Three more shadow scans follow, each stepped up again slightly more than 1 EV to the previous scan. Basically one highlight scan which is guaranteed to capture any highlights present, followed by a prime scan stepped slightly more than 1 EV up (it is brighter) to record the primary image content. In my approach, 5 different scans are taken from each film frame. The left image (“raw scan”) shows one of the original scans 2016 x 1512 px. The image marked “raw scan” is the data directly from the scanner, the image marked “release” is the image which had to endure a lot of processing before it came to life.
