The result: Darktable gives the option to disable gamma correction, called "base curve." As stated before - automatic conversion from Hugin was never successful so I opted to convert by hand.
I took a series of shots of a colour checker and exported tifs from DT with the base curve ON, OFF, and added one batch exported with default from Adobe. These images were then processed with the Average filter to get the average colour of each image and compared side by side. Using an eyedropper I checked the RGB values of each averaged square and copied the values into a spreadsheet, then graphed it out. This showed a slighter deviation than I expected in the gamma corrected graph, and deviations between RGB values even within the linear graph - again, since all images are averages of the same scene under virtually equal lighting conditions (10 second difference in sunlight) all the values should change equally. Regardless, at this point I am content saying that the method works, albeit with limited precision, and I will have to produce more images to test the scene precisely. -- A list of frequently asked questions is available at: http://wiki.panotools.org/Hugin_FAQ --- You received this message because you are subscribed to the Google Groups "hugin and other free panoramic software" group.
