Hi Nik
I did some more investigating. I think it is an issue with the olympus *.ORF RAW file format. When I convert the file to DNG the problem disappears. So the workaround is to convert to DNG files, which is pretty easy using Adobe’s converter.
I am relieved to have found a workaround, I really like this application and appreciate the work that has obviously gone into it.
Best
Nick
PS out of interest I will still send you a couple of picture to show you the issue.
