Access / reuse results of color calibration
« on: 2014 June 29 15:46:23 »
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.

If I understand what you're trying to do, you can use PixelMath to multiply your image(s) by constant factors.

Thanks for the reply. The problem I have is that I don't know how to access the values / factors that are calculated by the ColorCalibration tool (based on White / Black references) to apply the same transformation to other images.

Maybe I'm going about this the wrong way, actually I would have expected to get consistent results if I just apply the ColorCalibration tool to all my images using the same white / black reference. But I sometimes got wildly different results for similar input colors in different images.

PS Sorry for late reply, forgot to check back before vacation - also did not seem to get an email notification for your post - but I found the Notify button now :)

The ColorCalibration process writes the correction factors to the process console.
