A question about film Exposure Index
"A film rated at ISO400 with push processing up to EI 1600"
Is that analogous to a digital sensor with a base ISO of 400 that we can select ISO up to 1600?

Re: A question about film Exposure Index
actually, technically speaking, we are still underexposing the exposure and then pushing the signal digitally (through amplification), just that it all happens in the camera's electronics... so an argument could be made that it is the same as pushing film... except that for digital RAW files, we can do it again in post as well... so it's like we can choose to do it in camera or in post (although the results of doing it in post will probably not be as good as doing it in camera, all else being equal)... YMMV
