So what current camera/sensor combinations have the same exposure > latitude as film? Most any of the high end 35mm-esque digital cameras should handle 8 stops or more. The new Kodak 14n has a dynamic range of 69dB, which is about 11.5 stops. The professional backs can handle 12...and that's actually "old" technology (Leaf Volare/Cantare). Check the Kodak web site, and see what their full frame CCD offering is. That'll tell you what the sensor is capable of. > I know that in the video world the chips in the HDTV cameras have > no where near > the latitude that you'd find in Super-16 or 35mm. Different technology, they use different sensors. They are much faster, as they have to run at a much higher frame rate. > What are they and when will we see the price-point drop to > non-heroic levels? I don't set the prices...but the Kodak 14n is priced at $4k...which is a lot of bang for the buck compared to the competition. > Peltier cooling for the chip is cheating. Why? Cooling is actually key to getting performance from these sensors! Regards, Austin - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
