Hi All,

Greg, is he confusing ISO with shutter speed?  What light conditions is he 
shooting in?

General rule of thumb for daylight is an ISO of 100 or 200 for daylight.  400 
to 800 for an overcast day.  800+ for low light conditions.  Think what it was 
like when you used to buy film.

Shutter speeds vary depending on the speed of the object.  I work with 1/1000 
or even 1/2000 at sea.  Laurie is right in that a minimum of 1/500 is good for 

Hope this helps?
