Looks like Android is stripping GPS EXIF from photos whenever they're shared.

Affects QuickShare / Bluetooth - https://issuetracker.google.com/issues/485307531
And the web photo picker - https://issuetracker.google.com/issues/40287342

Basically the only way to get geolocation is using USB transfer.

Like, I get the privacy aspect, but it is so annoying to explain to users of @openbenches that they can't upload via the mobile website any more.

#Android #EXIF #Privacy #Geolocation

Getting rather frustrated that the latest Android strips location EXIF from the web file picker.

Doesn't seem to be any workaround that'll let you pick a photo and have a web browser see the geolocation.

Like, I get the privacy issues, but it is rather frustrating for location-based web apps.

(Before reply-guying, please test if the code you found on a 4 year old StackOverflow post actually works on modern Android, thanks.)

Невидимый след: автоматическая очистка метаданных из буфера обмена на Python

Существуют десятки утилит для очистки метаданных (от ExifTool до встроенных средств ОС), но у всех них есть общий минус — они требуют ручного действия. В результате родился MetaPure — фоновый демон для Windows, который перехватывает файлы в буфере обмена в момент копирования и бесшовно выжигает из них метаданные, прежде чем вы нажмете Ctrl+V . Windows хранит скопированные файлы, почему парсить XML напрямую иногда лучше, чем использовать готовые библиотеки, и какие грабли поджидают при работе с win32clipboard .

Bei den Bildern passt alles.
Aber die Videos bekommen einen Filenamen der den Timestamp der Aufnahme in meiner Zeitzone richtig wiedergibt.
Aber die Timestamps in den Exif-Tags sind offenbar in UTC eingeschrieben... ohne Angabe der Zeitzone. Die Videos werden damit in #Memories auf #Nextcloud im Winter um 1h und im Sommer um 2h zu früh eingeordnet.

Extracting Video from Motion Photos on Linux

Modern Android cameras can take "Motion Photos". They capture a few seconds of video from before and after you hit the shutter button. You can then either select the bit of the photo where no-one is blinking, or you can send the whole thing as a little movie.

Some apps (like WhatsApp) will play the motion photo when the image is selected, others will just show a static image.

So how do you extract the movie from the image using Linux?

Step one, let's take a look at the EXIF metadata in the image. Here's what running exiftool photo.MP.jpg gets:

Motion Photo                    : 1
Motion Photo Version            : 1
Motion Photo Presentation Timestamp Us: 866808
Directory Item Mime             : image/jpeg, image/jpeg, video/mp4
Directory Item Semantic         : Primary, GainMap, MotionPhoto
Directory Item Length           : 46353, 2106347
Directory Item Padding          : 0
MPF Version                     : 0100
Number Of Images                : 2
MP Image Flags                  : (none)
MP Image Format                 : JPEG
MP Image Type                   : Undefined
MP Image Length                 : 46353
MP Image Start                  : 2570425

That can be cross-referenced with the Motion Photo metadata specification.

We can confirm this is a Motion Photo, Version 1. The video portion at 866,808 microseconds (about 0.8 seconds) is where the main photo is taken from.

The file starts with the image, then a GainMap (for HDR), and then the video.

Somewhat obtusely (in my opinion) the Directory Item Length only shows "secondary media items" - in this case, the GainMap and Video.

The filesize is 4,723,125 bytes, which equals the sum of the three values; 46,353 + 2,106,347 + 2,570,425.

So, to get the MP4 video, we need to extract the last 2,106,347 bytes. This can be double-checked by taking the filesize and subtracting the MP Image Start and the MP Image Lengths (4,723,125 - 46,353 - 2,570,425 = 2,106,347).

The extraction can be done with dd but it's probably just as easy to use tail to read the last N bytes of a file:

tail -c 2106347 photo.MP.jpg > video.mp4

You can verify that the video is valid by running ffmpeg -i video.mp4 - the output will be lower resolution than the photo and will only be a few seconds long. It will play in VLC or any other standard player.

Try It Yourself

Here's one of my motion photos - it should present in your browser as a still image, but run the above code to extract the video.

Click the photo to download the full version rather than the optimised one.

Day 21 of #ITAdvent. From February 2026, #MicrosoftTeams will remove #EXIF #metadata from shared photo's, which can include location data. This is a good move as #Purview #DLP (as far as I know) cannot use EXIF data in it's policies.
Currently on the #Microsoft365 Roadmap #542795 under https://www.microsoft.com/en-us/microsoft-365/roadmap?&searchterms=542795

so ...

My #theory is that if we were to #backtrace on the stack trace from the #EXIF data inside the Microsoft Word cloud doc, we'd get a bunch of fluff from either thesaurus.com or from #Cambridge dictionary, showing ...

that the overpaid, over-confident putrid sack of diarrhea being paid in future Palantir stock options from the year 4044? Well that genius just copied and pasted a bunch of #synonyms from these sources into his Microsoft Word doc.

And based on that prediction, it would be fairly easy to draw a smaller word cloud of concepts that Drumpf scribbled (in thick black Sharpie marker) into his Choose Your Own Adventure As A Fascist Dictator coloring book. I heard they're selling them on #Amazon to CEOs complete with #wireframe diagrams for that "Generate an AI-based graphical illustration based on the mental illness in your head" to which the Palantir employee then inputs Drumpf's "cloud of scary words" to make this document.

@jwildeboer @homelab I had the script, which did the work like described:

- Takes all picture files in current directory (using find+file commands for that)
- Renames files with YYYYMMDD_HHMMSS pattern using the EXIF creation date or filesystem's mtime if no EXIF.
- If there are some files made in the same time — the "_DN" (N is a number) suffix will be added to the filenames to prevent loss of such files during rename.
- Has an option for test run, without real rename.
- Has an option to skip already renamed files.

Note: it was written for Bash first, so it will work not only for ZSH (after adding a proper she-bang) — I just used it as ZSH function.

FFS, why can't Android Gallery Apps read Exif data from AVIF images? 😑

I have the Fossify Gallery¹ on my phone.
It lacks e.g. that editing Photos will greatly reduce their resolution 🫠

Now I started converting my JPGs to AVIF, preserving the Exif data of course.
But tada, it won't read them => sort by capture date won't work 🤷🏼

Tried another one², but won't read them either. 🥲

About 100 loc into adapting exvi2 into one of my howngrown tools and I remember why I avoided that in the past. The #exiv2 API makes me want to sanitize by brain each time I look at its documentation or implementation.

Handling image metadata sucks, be it #EXIF, #IPTC, #XMP or anything else. However, a library shouldn't *increase* the pain.

Anyone aware of a halfway useable alternative that can be adopted/integrated into other languages? So ideally written in C or C++. Rust *might* work too.

Pour les photographes, sous mac, ayant besoin d'éditer les #exif et #iptc de leurs photos, je vous présente Apnee, une appli que je développe qui vous permet de modifier vos exifs facilement.

Ouvrez votre photos, modifiez vos données, enregistrez, simple et efficace.

Ca reste une première version avec sûrement pleins de défauts, donc soyez indulgents... mais je n'avais pas trouvé d'équivalent libre sous mac.
