One trick that is used when displaying differences between two images is to rebase the image so that the "zero" color is actually <tt>#808080</tt>. Then you can show differences that are both positive and negative. –[[User:Dkf|Donal Fellows]] 11:08, 29 December 2009 (UTC) |

Hi! Thanks for the suggestion! Unfortunately, because the differences were so small, the rebased image was fairly uninteresting, so I settled for heavy contrast enhancement instead. I have updated the image and hopefully it's easier to see now. -- Oofoe |

One trick that is used when displaying differences between two images is to rebase the image so that the "zero" color is actually #808080. Then you can show differences that are both positive and negative. –Donal Fellows 11:08, 29 December 2009 (UTC)
