Although I am a long time amateur "wannabe" photographer, I never really got too deep into the technical side of photography. (Which probably explains the wannabe status...) And now I have a question about dynamic range... From what I read, most digital sensors do not have the dynamic range of an excellent film. However, I have found that in situations where contrast is great, if I expose for the highlights, I can often recover details using Nikon Capture's D-Lighting. This tells me that the detail in the shadows is in fact recorded by the sensor. Cameras like the new Nikon S1 has D-Lighting built in (as does cameras by other manufacturers...). My question is this: Is dynamic range really limited by our sensors, or is it really limited by the logic that the camera processors use to convert the light to a digital file? Could firmware improvements help in this regard?
