My camera's firmware (Powershot A580) has this option (of switching from NORMAL to MACRO), but everytime I power down the camera and turn it back on, the focus mode changes back to normal. I'm looking for a way to permanently change this setting to MACRO. I don't need very detailed responses/replies. Only what I should look for. Thank you!
P.S. I already have a general idea of scripts, so any pointer regarding the use of these would be very useful.
