Ok Kay - I've Read Ghillies' advice, and there is some sense lurking in there somewhere, but unravelling it is a different matter...
Basically, something has gone very wrong with your first pic, and it looks like it may be a camera malfunction on the processing side of things...
The other pic is horribly over-exposed. Looking at the exif, you have a slow shutter speed and very wide aperture, so you were letting far too much light into the camera. Remember that the bigger the aperture, the smaller the number, so f2.8 is a very wide aperture, for dim light, and f16 is small, for bright
