  Worth noting as well that this is a summer image so you are looking at an un iced surface

  Should look something like this.

  UPDATE: If you click on the original image and hover over it, a larger image will appear on the right (in negative?). I have only just noticed it! This will be a great help to users that are having trouble differentiating peaks from troughs.

  Nope not the negative, just a magnifier of the same image. It might make some features pop more but it's the same image. It's a new feature added in the past week or so.

  Meg, it was a negative for a short while on my machine (honest) but only for a short while. The zoomed image is a useful addition, thanks.
