Comment 3 for bug 2049641

Thanks for the test files.
But I can't reproduce the issue. When using your file, dcraw processes both files without problems:

The log of dcraw looks identical to your run. So I don't understand why in your case the wb multiplier are not correctly read from the log. In the log they appear correct, but they are not correctly parsed for the second run of dcraw.

Maybe your dcraw version adds some non-printable to the log? Could you try another dcraw version?

Just to be sure: you are using the latest Hugin version 2023.0?
