This would be a great plugin. Any update on how to achieve this capability?

The examples I used are at http://sumsearch.org/photos.shtml . The photos are only a segment of the face to protect the patient's privacy. In addition, the server with the photos is having some trouble and at times the page is not display today. Any help is appreciated. Thanks.

Thanks for the ideas. Due to privacy issues, I cannot put the complete photos in public. However, a link to extracts of the photos and my initial, primitive test with color balances and brightness is at: http://sumsearch.org/photos.shtml The values for the darkest pixel of the eyebrow are: Before photo: 43 30 21 Current photo: 48 43 43 Before photo with adjustments to balance and brightness: 47 40 41 Thanks

Does anyone have suggestions on how to use existing PainNet program or plugin features to solve the following problem? Sometimes in publishing of medical research, we need to show the changes in a patient's appearance over time. Inevitably, the two photos will be in different lighting. For example, the current photo may be in the flourescent light of a hospital while the older photo may be in the incandescent light of a patient's home. I have tried a method to identify the darkest pixel in a feature common to both pictures (for example, eyebrows) with the following results: New photo: R:48 G:34 B:30 Old photo: R:45 G:43 B:40 So, how should I adjust the old photo? Simply add either the relative or absolute difference between the channels above to the entire photo? Is there a plugin that supports this? I looked at ColorMatch and ScriptLab, but did not see a solution. Thanks
