This is a bug that was fixed in PureRaw 2 but then reintroduced with an update and is still not fixed in PureRaw 3:
If you select a different then native aspect ratio on a camera, e.g. with an OM System OM-1 “3:2” (native is 4:3 for MFT), the RAW still is a 4:3 but the metadata contains the crop information “3:2”.
If you open the RAW in Lightroom which interprets this data the image is shown with a crop to 3:2 which can be reversed with the crop tool to 4:3 again. This also applies to converted DNGs.
If I use PureRAW 3 though the exported DNGs (or any other file format) miss that information and the crop to 3:2 is not shown in Lightroom. Instead the image is shown without a crop and it’s native 4:3 aspect ratio.
Please fix this! I reported this 3 times (3 tickets!) to your support division. The first time it was fixed, than the bug was reintroduced by an update of PureRaw 2 and since then it’s still not fixed. I won’t provide any additional data anymore though because I’m sick of it: I already done that 3 times and the bug was confirmed every time but not fixed in the timeframe I was told except for the first time before it was re-introduced. This really is annoying and you should work on your internal processes and your release-management: Reintroducing already solved bugs happens but then not fixing it again for about 4-5 months is really a bad joke…
