Save images with saturated pixels

Browse source 
If any pixels in the manually processed raw image end up
saturated (>255), this causes an error. I've now manually
clamped the values between 0 and 255 to fix this.

It would probably be a good idea to warn when this happens,
as it does mean we're losing data.
