I don't remember how to check what settings pictures were taken on in EXIF, however there was a small period of time after my wife had used my camera that she changed the camera from P mode to Portrait without me noticing for a few shots.. anyway if thats what you guys are talking about theres the explanation, i only shoot on P really.
aside from that, thanks for all the rest of the comments. the location is in Big Sur, CA its a beautiful spot and its where me and my wife spent out honeymoon (that and monterey, ca)
