Description

Hi,

please add support for the SJCAM SJ6 LEGEND. I just added 3 RAW files via raw.pixl.us in different FOV / resolution.

SJCAM provides a DNG converter, but while LR does, DT can´t read the converted DNGs (see screenshot).

Additional files (tif, dng) can be provided if needed. Please send me a note.

Additional info and sources of the DNG converter can be found here: https://sjcam.com/de/sjcam-raw-v1-2-0/

Thanks a lot
Jürgen

Here is one dng from that converter.

0x0102 Exif.Image.BitsPerSample                     Short       3   6  16 16 16  16 16 16
0x0106 Exif.Image.PhotometricInterpretation         Short       1   2  32803  Color Filter Array
0x0115 Exif.Image.SamplesPerPixel                   Short       1   2  3  3

So uint16, but 3 channels AND CFA.
And that makes no sense. Never seen anything like it.

Hi Roman,

thanks for your fast response. I have to admit that I'm only a user of darktable, not a programmer ;-) and do not completely understand what you stated. Looks for me as if it would be easier to directly read the RAW File. Any chance to see this in one of the next releases ?

  • % Done changed from 0 to 50

So good news bad news.

Good: i have added support for those two smaller raw files.

Bad: the largest raw clashes with already-existing raw (GITUP GIT2P chdk-b).
Since the only way this matching can be done and is being done is by matching the filesize, this was inevitably bound to happen sooner or later.
I am unaware of how this can be resolved.
