Question: How much image information can be captured and stored on a single frame of 35mm color negative film and how does that compare to todays best digital cameras? Answer: A single frame of color film scanned at 4K by 3K resolution with 10-bit depth contains about 50 megabytes of data. However, there is actually a lot more information than that on each frame of 35mm film. We have conducted tests where we have scanned film at 6K by 4K resolution at 10-bit depth, resulting in about 100 megabytes of data, or twice as much image information. In comparison, a typical CCD or CMOS RGB 3- sensor 1920 by 1080 electronic camera with 10-bit depth records 8 megabytes per frame, assuming that there is no sub-sampling or data compression. A single CFA sensor 4096 by 2048 camera records about 10 megabytes of data. So the simple answer is that todays best film technology enables you to record 5 to 10 times more picture information on a single frame than the best contemporary digital cameras. cinema-lifestyle/cinematography/news/whyfilm/index.html
