The image in the original post, e. g. https://www.dropbox.com/s/e7zjcaln4xdjke1/artefact_brightness.JPG?dl=0
has another image at the side - that is the darkest exposure I made. I tried adjusting levels, but the main problem remained in that the highlights around the gray area clip sooner than the gray goes to white. I recorded the process, you can find the file at https://www.dropbox.com/s/78db4w7dc5rr94r/luminance_manipulation.zip?dl=0 . The video is a little wonky, it only recorded part of my screen, but it shows the issue is not related to levels in Luminance. The password to the zip is *hugingroup*, In fact, I noticed that the grey area looks somewhat like the areas at the base of the image - among the rocks. It is as though parts of the image were masked out. I uploaded the work files and photos as well, under the same password https://www.dropbox.com/s/20zs4rdm17mbg0h/20180812_files.zip?dl=0 - note that mapped, 8bit tif layers are exported properly. -- 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.
