Description

When using darktable to transform olympus raw files (.orf) into jpegs, the generated jpeg files are much darker than the jpegs generated by my olympus E-PL8. Attached is an example with both jpegs and the raw file. Do you know why this happens?

Here is the version I'm using

$ darktable --version
this is darktable 2.7.0+260~gb94a93696
