I saw a very interesting video today which makes short statements about the disadvantages of digital cameras vs film. The video was shot at Kodak Panel at Cine Gear 2011. Rob Bummel from Kodak goes over the differences between CCDs and Film. It's very interesting to see that there are many problems that haven't been solved yet.
Some of them you actually know, but you didn't know that it happens for the reasons that are explains in this video. When watching this comparison video I seems like film is the newest technology, not digital :)
In the first part, Rob talks about the three layers (yellow, cyan, magenta) of film, which there are actually many more layers. Another thing is that film doesn't have filtration, which means the light doesn't pass through filters that only pass the light of a specific color spectrum
Even in terms of resolution, there is a big difference between film and digital. 100% of the area of the film is sensitive to light. On sensors you can see that the fill rate is very small. Just look at the video and you'll see that a very small part of the CCD area is sensitive to light. So a 35mm full frame sensor on a digital camera isn't like a 35mm on film. It seems that marketers used numbers that are far from telling the real truth.
Just watch this video, maybe it will convince you buying a film camera instead of a digital camera?
Thank you for posting those useful information.
ReplyDeleteVery interesting especially the fact that photosites are sensitive to the altitude and could fail.
I am now courious to know whether the foveon sensor and Cmos sensors generally, have the same problem as the CCD has.
Ciao.
Hi doubleluca,
ReplyDeleteI'm on it.. interested as well
