For Lightroom HDR Merge, is it better to do Noise Reduction with the individual raw images (ISOs may differ), or only to the resultant merged DNG?
Are there any Develop variables which are better done to the individual raw images rather than the merged DNG?
Thanks in advance.
I have not seen a difference.
Great question and a good test to run. If you have bracketed your images to cover a wide range of exposures processing them before merging them via HDR defeats the purpose in some cases. Using HDR to merge the bracketed images should provide a good result that can be finessed as desired.
