It sounded significant to me because Kodak's digital cameras act more like
chrome film than negative film. They don't like contrast that much, and
prefer underexposure to overexposure. Besides, that's a number they used in
the ad. I wasn't trying to make it sound like that was the only important
statistic. What's more important with this kind of camera, I guess, is how
long an image takes to "shoot."
