#975 Can't import DNG files from Nokia Lumia 1020
Hi,
As you may know, the Nokia Lumia 1020 supports RAW format (DNG). When connected, the device is seen via MTP. Unfortunately, while importing JPG and DNG files work on Windows, it fails on DNG ones on Linux.
The operation is said to be unsupported (error 6).
gphoto2 --list-files shows both the JPG and the DNGs, for instance:
35 WP_20140308_20_57_35_Raw.jpgrd 1488 KB image/jpeg
36 WP_20140308_20_57_35_Raw__highres.dngrd 42653 KB application/x-unknown
(the Lumia takes both the RAW and a JPG)
The DNG files can be seen in a file manager but when copying, it fails. Has the DNG format to be added to the WP8 driver?
I can provide more details if needed.
Thank you in advance
regards

Hi
I have further investigated and here is an additional input if it can help.
For sure, JPG can be copied or opened directly on device. But .DNG or .NAR (which is a specific Nokia format) won't even copy, because of
I've tested two things: the gphoto2 shell and the -P command. First the shell:
For a DNG:
When for the associated JPG, everything goes well:
Now the gphoto2 -P test. I have a huge logfile obtained by :
env LANG=C gphoto2 --debug --debug-logfile=my-logfile.txt -P
which weighs like 30 MB even bzip2-ed.
Basically, it's the same:
As you can see, the saving lines are missing for the DNGs.
I have uploaded the debug file here if it can help: http://1drv.ms/1gyhuOj
I'm happy to provide further details in order to solve this issue, that apparently is not an isolated case, refer: http://t.co/gpzp3Jm6kx
This being said, I know that copy of these DNGs can work actually. Somebody just installed ubuntu and it worked out-of-the box: https://t.co/SpMa5KzSRf
Besides, his libgphoto2 and libmtp libraries are older than the ones I use (I run Debian unstable up to date).
It's a real pain to boot a virtual machine just to copy the raw files (no need for jpgs), or to reboot under Windows just for that.
Thank you in advance and again happy to provide further details or test whatever is needed to be tested.

Glad to see it violate the DCF specs, much like Android....
Not that I think it is the problem here.
please test 2.5.4 , i relaxed the file download restrictions on mtp devices
Just compiled new version (2.5.4 on gphoto2 and libgphoto2) and I'm running a little bit different problem right now:
Is there some library missing or what is going on? :)
no additional library required.
the screen is unlocked when plugging in?
can you capture a debug trace (--debug --debug-logfile=xx.log)
Yup, the screen is unlocked. Tried also with with --camera="USB PTP Class Camera" and --port option, same results.
The debug file is without any of those parameters.
One of my 2.5.4 fixes for a different camera was too eager and broke this due to slight incorrect protocol interpretation by the nokia.
can you apply the attached patch, where I try to do that a bit better..?
Just patched and I have good news. Listing files is working perfectly fine and importing those DNG-files is also working fine.
Do you want any debug log to confirm this, or is my word enough? :)
Anyways, thanks for fixing this.
hello my friend,i am an new user of linux from greece but an photographer and cannot transfer my dng photos,have the same problem with you.how did you fix this?do you maybe have an deb from 2.5.5 gphoto2 for my to install it ?
thanks for testing! :) I believe you ;)
