Re: More a function of how they define DR

Only if you are trying to resolve details that are simultaneously at the limits of resolution and DR. How often does that happen? Probably almost never.

Are you saying binning outside the camera doesn't help? I don't think image processing software bins pixel anyway when downsampling an image--I think it does a regular LPF.

Arithmetic averaging is a crude form of spatial-frequency low-pass filtering. Other down-sampling algorithms provide steeper slopes of roll-off (at the price of inducing "ringing" / "artifact" effects).

When I said "regular LPF" I just meant they don't do binning, they use some sort of weighted moving average.
