Is Dynamic Range & Exposure Latitude the same thing as I think it is?

Does anyone know what the exposure latitude is on a digital camera and does the sensor size or pixel countmake any difference?

I remember from my dark past readingthat the exposure latitude on B&W film was 16:1, on color print film 8:1, and on slide film 2:1. I have not found any info on what the digital ratio is on this site or others??

Any input would be most appreciated.:-)

I think the answer to this is such:
Dynamic range is the difference between the darkest dark and the lightest light in a given frame. Anything lighter will clip and anything darker will be lost in the shadows.

Exposure lattitude is within this range plus a few constraints. The darker the exposure the more noise, and some of the colors seem to clip earlier than others(ie. red).
I would say from my experience though that it is probably around 1.9:1 and 2.1:1. Though i have not measured it myself.
