您可以去修改那些網上的數據了
Scanning film
In contrast to digital photographs, color negatives and slides consist of multiple film layers that respond to light differently. As a consequence, transparent originals (especially positive slides) feature a very high dynamic range.[12]
Dynamic ranges of photographic material
Material Dynamic range (F stops) Object contrast
photograph 5 1:32
color negative 8 1:256
positive slide 12 1:4096
When digitizing photographic material with an image scanner, the scanner must be able to capture the whole dynamic range of the original, or details are lost. The manufacturer's declarations concerning the dynamic range of flatbed and film scanners are often slightly inaccurate and exaggerated.[citation needed]
Despite color negative having less dynamic range than slide, it actually captures considerably more dynamic range of the scene than does slide film. This dynamic range is simply compressed considerably.
如果您有幫人掃描底片的話，我覺得你真的要再搞清楚一下，畢竟我不是靠那個吃飯的
