Description

Darktable currently supports most Panasonic cameras that output RW2 type RAW files. The m4/3's sensors in these camera's unsurprisingly have a native aspect ratio of 4:3. Most Panasonic cameras have the added possibility to crop the RAW file in the camera body. These special "cropped" RW2 files are often not very well supported yet.

Usually each camera has four "crop" modes:
- 4:3
- 3:2
- 16:9
- 1:1

To help us add support for these, we need a single RW2 file for each of these aspect ratio modes.

Each shot needs to be at a low ISO, and should be reasonably decently lit. Contents of the shots doesn't matter too much. Please provide something with some structure and detail, and please avoid submitting shots with recognizable people in them.

While not directly related to Darktable we'd also appreciate it, if you'd check if rawsamples.ch already has a sample for this camera, and if not, please submit a sample to them as well.

#6 Updated by Alex Stepanov over 2 years ago

Yes, of course. I loaded all the samples in https://raw.pixls.us/. But while the search returns no results with uploaded files by me: "No matching records found". May be it takes some time for verification or indexing

There was no message that they were uploaded successfully, and are now avaiting manual verification?
If no, feel free to report that as new issue on https://github.com/pixlsus/raw/issues

OK!
I think that all files were uploaded successfully. After each upload i seen screen where been prompted to write comment for file. Image aspect ratio for the all RAW files been detected correctly!
I'll check later how works search for downloaded files. If search will not return result i will report an issue.
PS: I uploaded these RAW-files on a rawsamples.ch too (but this site seems abandoned)

#9 Updated by Alex Stepanov over 2 years ago

I tried to open the test photos. It turned out that the darktable 2.2 opens RAW-files with an aspect ratio of 4:3 (and only them).
