GreglyI ran into a weird Unicode issue with EXIF tags in a JPEG recently: the “user comment” field was in Unicode, but it was an encoding I couldn’t identify. It started with the bytes “UNICODE\0”, followed by what looked like UTF-16 (\x00 bytes interspersed with 8-bit ASCII) but no byte-order identifier (\uFEFF or \uFFFE). The thing is, Windows and various tools decode it just fine, but my code attempts to do so have all met with failure. Ideas? <a href="https://retro.pizza/tags/photography" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#photography</a> <a href="https://retro.pizza/tags/programming" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#programming</a> <a href="https://retro.pizza/tags/jpeg" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#jpeg</a> <a href="https://retro.pizza/tags/exif" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#exif</a>

utzer [Pleroma]Ich bin überzeugt: Fotoverwaltungssoftware sollte Metadaten immer direkt in den Bilddateien speichern – plattform- und softwareübergreifend nutzbar. Ob Gesichterkennung, Beschreibungstext, Kategorien oder manuelle Tags – all diese Infos gehören nicht nur in eine Datenbank, sondern auch als Metadaten direkt ins <a class="hashtag" href="https://soc.utzer.de/tag/bild" rel="nofollow noopener noreferrer" target="_blank">#Bild</a> (EXIF/XMP/IPTC etc.). Ich habe im Laufe der Jahre zwei Programme intensiver genutzt: Damals unter Windows: <a class="hashtag" href="https://soc.utzer.de/tag/picasa" rel="nofollow noopener noreferrer" target="_blank">#Picasa</a> (RIP). Heute unter Linux: <a class="hashtag" href="https://soc.utzer.de/tag/digikam" rel="nofollow noopener noreferrer" target="_blank">#Digikam</a>. Jetzt überlege ich, auf eine serverbasierte Lösung umzusteigen – aber immer bleibt dieselbe Frage: Wie <a class="hashtag" href="https://soc.utzer.de/tag/portabel" rel="nofollow noopener noreferrer" target="_blank">#portabel</a> sind meine Daten, wenn die Software ausfällt oder ich wechseln will? Eine Metadatenstrategie, die auf offene Standards setzt, erleichtert Backups, Migration, parallele Nutzung und langfristige Verfügbarkeit.

tuxwise(4/N) Having reflected a bit on your abstract assets, try to brainstorm as many of your related data and device assets as possible. Most of them will fall into one or more of the following categories:🪪 Personally Identifiable Information (<a href="https://mastodon.de/tags/PII" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PII</a>) 📇 Social graphs 🗃️ Data and metadata 🛰️ <a href="https://mastodon.de/tags/Geospatial" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Geospatial</a> data 🛜 Infrastructure 🫥 <a href="https://mastodon.de/tags/Accounts" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Accounts</a> and <a href="https://mastodon.de/tags/handles" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#handles</a>For instance, your smartphone photo collection "asset" probably contains geospatial data (<a href="https://mastodon.de/tags/GPS" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#GPS</a> coordinates in <a href="https://mastodon.de/tags/EXIF" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#EXIF</a>); data and metadata (phone brand and model, in EXIF); potentially also information about your social graph, in case your family, friends or acquaintances are on your photos.It's probably best to track your data and device assets in a spreadsheet, with the above categories as additional columns, so you can place a checkmark, where appropriate. I'd also suggest to add a column to track where the data is stored / the device is located.Here's a little list of 🪪 Personally Identifiable Information (PII), to get you started (other categories in next posts):🪪 Any kind of identity document 🎂 Dates of significant life events 👆 <a href="https://mastodon.de/tags/Biometric" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Biometric</a> data ⚕️ <a href="https://mastodon.de/tags/Health" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Health</a> data 🧬 <a href="https://mastodon.de/tags/DNA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#DNA</a> test results 👪 <a href="https://mastodon.de/tags/Genealogy" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Genealogy</a> data …Start of this thread: <a href="https://mastodon.de/@tuxwise/113503228291818865" translate="no" rel="nofollow noopener noreferrer" target="_blank">https://mastodon.de/@tuxwise/113503228291818865</a><a href="https://mastodon.de/tags/ThreadModeling" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ThreadModeling</a> <a href="https://mastodon.de/tags/4D" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#4D</a>

Nick MurisonI'm currently trying to rid myself of <a href="https://infosec.exchange/tags/Lightroom" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Lightroom</a> and <a href="https://infosec.exchange/tags/AdobePortfolio" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#AdobePortfolio</a> and move to <a href="https://infosec.exchange/tags/darktable" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#darktable</a> and <a href="https://infosec.exchange/tags/hugo" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#hugo</a> instead. One issue I've stumbled on is that I've historically used the image <code>Title</code> instead of the image <code>Description</code>, but both LR and DT have tended to write the image <code>Title</code> to the <a href="https://infosec.exchange/tags/IPTC" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#IPTC</a> or <a href="https://infosec.exchange/tags/XMP" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#XMP</a> metadata categories, not to <a href="https://infosec.exchange/tags/EXIF" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#EXIF</a>. As of right now <a href="https://infosec.exchange/tags/hugo" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#hugo</a> only seems to read <a href="https://infosec.exchange/tags/EXIF" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#EXIF</a> tags, so my photo titles aren't showing up when a <a href="https://infosec.exchange/tags/hugo" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#hugo</a> theme tries to display captions. Going through 100s of photos and copying the <code>Title</code> to the <code>Description</code> would be a royal pain. But luckily <a href="https://infosec.exchange/tags/exiftool" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#exiftool</a> comes to the rescue. For an entire directory of JPEG files I can simply run:exiftool -tagsFromFile @ -'ImageDescription<Title' *.jpg This copies the content of the <code>Title</code> tag into the <a href="https://infosec.exchange/tags/EXIF" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#EXIF</a> <code>ImageDescription</code> tag. And now the captions show up :)

Alex WildIf you are interested in *where* I took a particular photograph on my website www.alexanderwild.com, click on “photo details” and you’ll get EXIF data and a little navigable map at the bottom.
