    That should be latest version 2.5.1, which OS? I downloaded your sample pictures and tonemapped resulting HDR with drago.

    I'm using Luminance HDR version 2.5.1 (with default parameters) on a PC with 16GB of memory installed, running full updated Windows 10 Pro 64bit operating system. Original jpeg images comes from a Canon T2i DSLR camera. I can confirm the occurrence of the artifacts (scattered horizontal stripes) reported by the Creator (sadsdas). I can add that artifacts are not created the same way in every run of the program, even when running on the same original bracketed picture set. If the given images are not too big (five or seven 18MP images, for example), you can even get clean results, with luck. Once given picture set gets really big (four to nine frame panoramas, seven to nine exposure sets, for example) the chances to get a clean result seems to be zero. The occurrence of the artifacts are not related to tone-mapping. Once occurred with one of them (in a given run), it will occur with everyone, including B&W tone-mapping. If I process the HDR image in another software (I have tried Photomatix Pro and Hugin) and load/open it within Luminance HDR, the subsequent tone-mapped images are all clean (but unhappily not the same, compared to what I get from Luminance HDR alone - not counting the artifacts, of course). I think it is not so useful to show my bad results since in my experience it can occur (or not) in any given image set, especially the big ones, but I will try to provide a zip file (these images were taken at night, but issues occur in daylight images as well). Auto alignment and auto ghost removing was not enabled. Exposure values were not manually edited. Thanks.
