Description

I'm having trouble editing certain pictures taken with my 5Ds. I note that the lens is incorrectly identified as a 300mm f/2.8L IS II when they were taken with a Tamron 28-70mm f/2.8 G2.

[rawspeed] (IMG_0879.CR2) bool rawspeed::RawDecoder::checkCameraSupported(const rawspeed::CameraMetaData *, const std::__cxx11::string &, const std::__cxx11::string &, const std::__cxx11::string &), line 168: Camera 'Canon' 'Canon EOS 5DS', mode 'sRaw1' not supported, and not allowed to guess. Sorry.

Please take one slightly overexposed raw shoot per each raw mode (RAW, mRAW, sRAW) per each ISO level you can set on that camera, including all sub-iso levels, and extended low/high iso if any, pack them into one archive, upload them somewhere, e.g. dropbox, and post the link.

I'll take it over from there.

Thanks for the samples.
For future reference, that is not what i meant by slightly over-exposed :)
I meant a normal, viewable image, but maybe with +1EV exp correction, at most.

#4 Updated by Emre Safak 12 days ago

These have +2/3 EV correction. I just shot the wall in front of me; that's why they might look weird.

That's the point, something less wall-y would be nice, but no need to reshoot, these will do.

#6 Updated by Emre Safak 12 days ago

I have an IT8 calibration target, if it helps. Sorry for the trouble.

I'm afraid this i won't be fixing. It's quite typical problem with off-brand lenses.
Normally exiv2 would be handling that, but i think they just gave up on that..

If it gets fixed at their end, does it get fixed here too? I found their ticket.

Well, it should, but since exiv2 is a system library,
it will only get fixed for you once your distribution updates to that version.
And all that is assuming darktable is reading the right EXIF field.
