I frequently need to apply identical processing to a batch of images (either for animations or mosaics). I usually do this by picking a suitable reference image, processing it until I like the results, then drag the history on the other images manually (for a small mosaic) or on an image container (for larger sets).
However, I found this to be a bit twiddly when automatic ColorCalibration was involved in the process. My white/black reference is usually a subregion of the reference image, but copying this seems to apply a little too much extra intelligence on the target image. So I'd actually just like to replace it with an AssistedColorCalibration using the automatically determined factors to ensure consistency. I'm probably overlooking something but I didn't find the factors, neither in the GUI nor in the script code.
