I stupidly lent my camera to a friend and he must have messed around with my settings. I'm now having issues with the photo playback. When I used to press the playback button (20) the photos just taken had numbers displayed that showed the total numb...

I think I might have accidentally changed a setting on my PowerShot SX70HS camera. I used to be able to adjust the exposure level before taking a photo by turning the main dial left or right. Now nothting happens when I turn the dial.
