I will post here since it is related to HDRMerge and this topic. I was able to get HDRMerge working. I am super rusty; I haven’t used it since it first came out! The more raws I merge, the more noise seems to be introduced, and the more I push the hdr, the uglier it gets. E.g., comparison between CRW_1597.DNG and merged CRW_1594-1597.dng (only 4 frames; 7 is worse) from the recent PlayRaw, brightened to have approx. the same mean statistic.
