Turns out that after I had downloaded all the pictures from the camera that had been sat there whilst we had no computer, I noticed that they are all slightly blurry on the left hand side.
After further investigation we discovered a lovely grubby fingerprint, about Alex size, on the lense of the camera.
So sorry that all the pictures seem to have a nice hazzy left side look to them.
It is quite obvious in the pictures of the firworks and also in some pictures I am about to post about Hamilton Gardens.
Joys of children, all I can say.
