It sounds like you should only post your message once, and don't do so
much cross posting, it is considered bad manner.  Some of the groups you
included have little to do with your digital camera.

    You should be able to change the "film speed" on your camera.  Lower it
to force a larger stop and less depth of field or raise it for more depth of
field.  ND (neutral density) filters also work and they work on digitals.
