Save "raw" picture in history

[nicolas-raoul]

Problem: Smartphones increasingly use post-processing and AI to make picture more vivid/interesting for instance by exaggerating colours or blurring the background. Unfortunately that often makes the pictures less representative of reality. The original is lost.

Idea: Also store a "rawer" version of the picture, if the camera app lets us have it. That one could be saved first, and then the post-processed picture could be saved as a new version of it. All versions stay visible in the file history, making it easy for user to decide which version they want to use:

Note: The format and filenames of the "raw" versions (when they are saved) are very model-dependent and settings-dependent, but hopefully we can implement this for one model/setting as a proof of concept.

Can I work on this issue?

@deek121477 Yes thanks!
What phone ad camera app are you using? The first step would be to figure out how to get the "raw" picture, please post your findings here :-)

[deek121477]

Thank you for assigning me this issue @nicolas-raoul
The phone that I would be using is Android and Adobe Photoshop Camera
And I more thing as I am beginner to this project
Can this issue be labeled as a good first issue or not?

[nicolas-raoul]

It is a good first issue in the sense that it is limited to a rather specific area of the app.
It is more difficult than the average "good first issue", though, but I am sure you can do it :-)

On my Pixel 4 phone the default camera has a setting called RAW+JPEG control which saves a .dng file in the Raw folder. My Galaxy phone also has an option to save raw images as a .dng.

Unfortunately I just discovered that DNG file upload is not implemented yet: https://phabricator.wikimedia.org/T21153
If we have a good proof-of-concept I believe we could raise the priority of that Phabricator ticket.

So I suggest starting with "HDR originals" rather than RAW, since they use JPG rather than DNG.

1. Install the OpenCamera app and open it.
2. Tap the 3 dots, tap HDR.
3. Settings>Photo settings>Save all images for HDR mode.
4. Take a picture (it takes time as the app actually takes 3 pictures.
5. Go to Gallery, find the OpenCamera folder. It should have 4 pictures: Low brightness, normal brightness, high brightness, HDR result.

So for now the implementation would be:

• When uploading a picture, the Commons app first checks whether it is in a folder called "OpenCamera" and whether the 3 HDR pictures are present.
• If yes, upload all of the 4 pictures one after the other using the Commons "file history" feature shown in the screenshot above. The HDR result should be uploaded last.
  (The advantage is that in the future whenever more powerful HDR algorithms get developed, Commons people can regenerate the HDR images. Also, for pictures with a historical value, specialists will be able to see all details that are not visible in the result HDR.)

Thank you so much for giving the guidance for approaching the issue.
I am done with OpenCamera Part and I have got 4 images too.

While uploading images on the commons app I have uploaded only 1 image as there was no option for 4 images to be uploaded. Here I am attaching the link to the image that I have uploaded:

@deek121477 At https://commons.wikimedia.org/wiki/File:Air_is_wild_with_the_leaves.jpg you can see a link called Upload a new version of this file. You will have to discover what API calls the form behind that link use. :-)

Okay. I will try.

While cloning git@github.com:deek121477/apps-android-commons.git

I am getting a message of: [ permission denied(public key)
Please make sure you have the correct access rights
and the repository exists.]
So can I use the git clone command of https://github.com/deek121477/apps-android-commons.git as in the android studio, all files are opening and working properly?

Also, is HAXM needed?
