又在亂講
你到底有沒有用過濃度儀阿?
負片如果從0.5開始起跳，Ansal Adams的Zone system就從此改寫了
其次，Zone system的精神才不是你鬼扯的那樣
麻煩你重新念原著(The Nagetive)一次，尤其是預視那一章
小弟還沒到實際操作zone system的程度
不過有買蔣載榮老師的書來看..
也覺得文包大大講的"zone system精神"好怪....
文包大大好像專長就是讓一些大師哭泣

所以您的意思是我的英文要加強？還是google有問題，因為我google的keyword 為＂dynamic range film", 找出來的數据再整理一下，如
http://landscapephotographymagazine.com/2011/dynamic-range-of-negative-film/
http://en.wikipedia.org/wiki/High_dynamic_range_imaging
我是忘了放stop, 你寫的我看不懂嘢？還是你的dr不是我的dr？
簡單說
你覺得哪一款正片可以拍下明暗差距高達12EV的場景? 然後亮部暗部細節都在?

簡單說你覺得哪一款正...(恕刪)
你為什麼不問他們呢？
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.
