Alright, I am happy there is a graph function in Hugin, thank you... but now this last message makes more sense, which I am not jubilant about. Allow me to explain -
I want to check if the photo stacks I am working with are linear or not. Yes; raw files are supposed to be linear, but Hugin does not work with CR2, only tiff. If I convert the cr2 to tiff it will probably add a gamma curve, but I don't know if and how, and so I wish to check the result. If nothing else my camera's sensor might be doing something funky as well. But if I can choose the type of image I have, then am I telling Hugin to (or not to) calculate the curve when stitching instead of only calculating the curve and returning the result. In the attached picture green shift is seen in the cloud. To my knowledge this means that the gamma curve has been calculated badly. I wish to know what kind of a gamma curve images have after I converted them from raw. pasteall.org/pic/3b53b009a65c4ba19d02dab9b458fb4a "For extracting the true camera response curve there are other algorithms which are better suited." Leaving aside that I don't know how to plug algorithms into Hugin, do you have any suggestions? I got HDRShop on academic license (which is supposed to be able to show you the calibrated response curve), but it either tells me 12 photos are not enough or it simply crashes when trying to generate the curve.
