The camera is in manual mode and is a Fuji S2 Pro.
If I have a set shutter speed (ie sync at 1/125 sec) and the correct
aperature reads say  F9 .
I need the shutter speed to be 1/125 sec.
But I need a lower F stop to limit depth of field.
Will minus 3 stops of exposure control alow this and give me a 3 stop larger
aperature?
Also what would my F stop be here?
Are there any drawback to use exposure compensation. ( ie noise etc.).
