IA represents auto? Coz normally for compact cameras, if you set
the mode to normal and if it's cloudy, the camera will not be able
to change the white balance to cloudy, and to compensate, it will
increase the ISO. Maybe you can try to use a mode where you can do
some personal settings (if there is) and at the same time you can
learn how to adjust to get the photo quality of your choice
yep.. intelligent auto function. actually, my camera can also
adjust any settings (eg. ISO number) without using iA funciton
(i.e. using normal picture mode)
