Very nice app, and I can tell you have put a lot of effort into it. Using it with a Galaxy Note 8 I have noticed that it does not record EXIF:CreateDate or EXIF:DateTimeOriginal tags. This is vital metadata which is typically recorded by every digital camera manufactured today, but (unfortunately) not by Open Camera. Might you investigate why this information isn't being recorded? Galaxies record this metadata natively, so I would think it should be available to you.
Thanks,
Mike

Do you have any of the options Auto-stabilise, "Stamp photos" or "Store location data" set? A known issue with any of these options is that some Exif data will be used. For the first two options, it's because I have to edit and resave the image - I can transfer some Exif data, but the Android API for handling Exif tags can't read these. For the third, it's because there seems to be a bug in the Android Exif API which results in some existing Exif tags being lost when I write the tags for direction. To fix these probably requires me to write my own Exif handling routines. In the meantime, I'll update the documentation, and make it so that storing GPS direction is a separate option to location.
If none of those options is set, I'm not sure - the Exif tags in that case aren't added or modified by Open Camera, they should be set automatically by the camera driver.

I am having another metadata issue. In windows, it turns out that the .MP4 file does not contain the metadata framerate, frame height, and frame width. I need this metadata in the "windows" metadata fields for import into various video editing software. I did make certain "Auto-stabilise, "Stamp photos" or "Store location data" were all turned off based on your comments above. I cannot find any other way to update these fields, so if it could come directly with the video file shot with Open Camera, that would be great. I am attaching a pic in hopes of communicating my issue more clearly.
Thanks, and I do really like other features of the program so thank you for a well thought out App.
I have the same problem, for example if a picture is opened with "exifviewer" (android app) a bunch of "unkonwn tag" appear. Acdsee confirms this by not reconising nor showing any metadata.. :-(

Mark, I dont get exif data when using Camera2 api. If i disable, exif data is there correctly. I am running on a nexus 6p. Let me know if i can help troubleshoot

My exif data was saving until I reinstalled OpenCamera yesterday. Now, the created date is not saved. The GPS data is saved. Is there a bug? If I disable "Store location data (Geotagging)" nd "Use Camera2 API", the created date is saved.

Hi,
I have the opposite question: is it possibile to prevent Open Camera saving any EXIF data, e.g. Phone model, Phone brand, software, etc...?
Thanks

This isn't supported I'm afraid. (I suppose there could be an option strip all the tags, but note it would slow down saving of photos.)

@Mark
Is it difficult to implement an option to disable saving EXIF metadata?
I don't know a lot about Android development but it sounds simple enough to me.
Is there a specific reason why you choose not to add such a feature?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Hi,
If you need to remove EXIF metada, you still can do it afterwards (on your PC) with ExifTool.
For instance to remove all EXIF metada in a picture called "filename.jpg", you simply need to write the following command line: exiftool -all= filename.jpg
ExifTool is really powerfull and you can do much (much) more to match any need you might have. Next step being to perform this recursively for all the pictures in one folder, etc.

I know we can use other tools to remove EXIF metadata. But sometimes you want to snap a picture real quick and send it to someone. There are other Camera apps with the option to disable EXIF metadata which saves a lot of time.
None of those apps hold a candle to Open Camera though, which is why I was hoping we might see this feature implemented in the future.

Subject: Missing EXIF info in OpenCamera DNG files
I found that taking RAW photos using OpenCamera on my Android phone appeared to yield DNG photos with missing EXIF data. The data is not really missing. However, many photo editing programs can’t read the “missing EXIF data”. The only EXIF data I see from OpenCamera original RAW files is GPS data. The solution for me on my Mac is to use the free Adobe DNG Converter app to convert the original RAW photos to Adobe’s standard DNG. After that, photo editing programs and the Mac’s Preview app will show you the aperture, shutter speed, focal length and ISO speed. This data then carries through to edited files such as tif or jpg.

Hello, hoping someone can provide some info on missing exif data for the focal length when using Open Camera. Please see attached.
When I view exif for an image that was captured with the OnePlus 7 Pro native camera app, I am able to tell that the user zoomed in on the image by reviewing the focal length data.
When I view exif for an image that was captured with the Open Camera app, I am unable to tell that the user zoomed in on the image by reviewing the focal length data. The focal length info shows that the image was not zoomed and the focal length data reports the data at the default zoom level - even though zoom was used.

Forgot to ask my question for the above post [https://sourceforge.net/p/opencamera/discussion/general/thread/fe0ff616/#97ce]
Are there any settings in Open Camera to make this better?
Can this feature be added to future updates?

Marvelous app!
But i am missing exif data in dng. Any chance to fix this sooner or later?
Especially as my device has three cameras. (Within the DNG files there are all named as device 2)

Hi,
I use OC in the latest Release on my Pixel 7 Pro With Camera2-API. In DNG no create date will be written.

I have the same problem, for example if a picture is opened with "exifviewer" (android app) a bunch of "unkonwn tag" appear. Acdsee confirms this by not reconising nor showing any metadata.. :-(
What happens if you try with another third party camera app - are there ones which record the exif tags you're after?
Mark, I dont get exif data when using Camera2 api. If i disable, exif data is there correctly. I am running on a nexus 6p. Let me know if i can help troubleshoot

It's on my todo, so hopefully in future. (Also see https://sourceforge.net/p/opencamera/tickets/315 .)
