Description

It seems that DT can't properly open files recorded in the new high resolution mode in the Olympus E-M5 ii and Pen F (Pentax also has similiar functionality). Details and example RAW files are here.

I have the same problem also in DT 2.0.7. The high resolution raw files from Olympus OM-D E-M5 mark II are imported as completely white images.

Just want to confirm that I too experience this problem using darktable 2.2.1.

A workaround is first converting the ORF to DNG (I only tried Lightroom) and then importing the DNG into darktable. See the attached image, which shows the high-res ORF and the corresponding DNG. (Interestingly, the ORF file was 104MB but the DNG was just 38MB; I guess the high-res ORF is uncompressed.)

Will support for high-res ORF files likely ever be implemented? I'd really like that and I would like to assist in any way I can. I'm afraid I can't help with coding though; C is definitely not my strong suit.

There are already samples on raw.pixls.us. Any chance of seeing support for this soon? Anything we can do to help?
