I just got a Minolta Dimage F-300 and noticed that some of my shots are
out of focus.  I use a backdrop in a studio with a combination  of
flourscent and incadecent lighting.  My model is positioned about 4'
from the background and I have used a combination of auto and manual 
modes with the flash on and sometimes off.  I was wondering if there
was one setting that would assure me properly focused photos?  My
photos are posted on the web and I trim them down to about 65K with an
image size of 640 x 480.
