badgettrg Posted February 23, 2012 Share Posted February 23, 2012 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 Quote Link to comment Share on other sites More sharing options...
