I bought a Canon powershot s80 when they first came out, and i have always been most impressed with it's performance. However lately i have noticed something a little strange.
When i use shutter speed priority or aperture priority the camera takes 3 photos in quite quick succession. One looks how it should (although its not 100%), then one is under exposed and the last over exposed. Ive looked around the menus and can't seem to find anything that might cause it.
Has anyone got any info? Is there a problem with the cameras software maybe?
