NHL, thanks. It's probably a contentious point, but cam manufacturers are beginning to address the dynamic range restriction. At the moment, I haven't seen so much improvement (worth the money) that I would change my policy of shooting 1/3 to 1 stop under, checking the histogram and stretching in PS.

On plasma panels, manufacturers specify 'contrast range' OK it's only a number and you need to look what's behind it. It has changed a lot in only a few years, but I haven't seen a similar figure quoted for digicams yet.

BTW video signals are bandwidth limited by design, ie they are already compressed by the various cameras to fit within the defined IRE levels...
