Re: Don't confuse dynamic range with color gamut

white -- just the opposite of what you said.

That sounds like a histogram stretch; trying to capture more DR than the camera can handle (or the output image can show), results in flat white areas for extended highlights, normal contrast for the captured/visible range, and any deep shadows all the way down to minus infinity EV are all rendered equally dark. If the extra DR is all on the shadow side, you won't notice anything different than if those deeper shadows weren't there.
