Digital cameras 101

[Grindel]

Hi All
Went on a warm holiday a couple of weeks ago, and came back to some real disappointment.  I have a Canon Powershot A75 - about 1 1/2 years old.  We took a few hundred pics on the vacation, and in the vast majority of them, all the whites come out as pink - I have pink chairs, pink teeth, pink beah....you get my drift.  Anyway, just looking  for some ideas as to what might cause this, and do I go to Canon and try to get it fixed or do I just write it off as a bad purchase.  FYI, the camera was set on "Auto" the whole time so it's supposed to be point-and-shoot, with all exposures, etc. taken care of.  I'm not a camera guy by any stretch, so that seemed the best bet.  
TIA
Rick

Hi Grindel and welcome to the Q&A Board!

Wow, sorry to hear about your photos! Do you do any photo editing at all? If so, what program do you use? Many programs have tools to remove color casts. We have a little about it here.

Check your white balance settings to see if you've inadvertently switched away from Auto White balance. If that's okay, try resetting your camera so all settings return to the factory default. If neither works, I'd call Canon.
