Quote: when taking photos in auto should the iso be set to auto? ruined lots of photos today because the iso was set to something different and i know it wasnt me!
Set the ISO to 200. Leave it there but watch the readout of aperture and shutter speed in the viewfinder - if you don't like a wide open aperture & slow shutter speed bump the ISO up. But set it back to 200 when you've finished.
Never trust automation, learn to do the job of setting the exposure yourself. When you've got an interaction between auto shutter speed and auto aperture and auto ISO it's very hard for me to believe that the damn camera would ever get the effect I wanted!
