Photography: Camera sensor size difference

"Think of a great photograph; i bet it didn't haven't a shallow depth of field."

one of Sally Manns. more photographic talent in her little finger than the whole of this forum put together.

true

all shot on 10x8 or larger with bugger all depth of field

ok, but, she's used a longer (0.5s?) shutter speed and water to achieve the same effect of subject in focus + background bokeh. So there goes your argument.
