@mattgriffin Don't know, cursory search suggests looking into the #IPTC standard. https://community.adobe.com/t5/illustrator-discussions/embedding-alt-text-in-an-image-file/m-p/15415746#M447335

I wrote a web page about processing raw data from my camera to make an image for viewing on the web.

Full day with content credentials discussions, exploring ways to help media orgs to adopt and utilise the benefits and forging action plans for the nexts and following steps.

Also super useful to meet people in person - much much easier to continue offsite and asynchronous talk with various orgs and people.

Great day, and really good location and venue, too!

#C2PA #ContentCredentials #ChainOfTrust #EBU #IPTC

so **each** key/value-pair of #metadata can be about 64kB.

This is sufficient to hold most annotations stored as #EmbeddedMetadata currently present in most file formats.
(eg #mp3, #mp4, #iptc, #tiff, #jpg, etc)

But from then on, the file-format becomes irrelevant for this task!

#TIL the `Object Name` field in #IPTC contains the title but truncated at 64 characters, whereas the `ImageTitle` field in #XMP or `Title`field in #DublinCore contain the full title. 🤷‍♂️

When you want to find the needle in the haystack… hum wait, no, a field in a photo metadata, there's #ExifTool: https://exiftool.org/TagNames/

Been busy deep diving into #digikam and #darktable... But I've entered a deeper rabbit hole —my really messy photo #metadata! Learnt a lot about #xmp #exif and #iptc, and using #exiftool (which is an amazing tool by Phil Harvey). #PhotoManagement #dam #photometadata

Nouvelle version de Apnee dispo !
Apnee c'est une app Mac pour modifier les #exifs et #iptc de vos photos.
Vous pouvez également enregistrer des templates de metadatas et les appliquer...

C'est gratuit et open-source.

Donc, vous avez besoin de modifier vos exifs et juste ça, rien d'autre ? C'est disponible ici :

Ah et, chose importante, le nom est un acroyme récusrisf :)
Apnee Php Native Exif Editor

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.

@Pyb okkkk ! cest pas faux, le #CCSD doit s'améliorer mais #Medihal propose quand même une URL stable, une description en #XMP et #IPTC un affichage et récupération des fichiers en #TIFF et si qq'un veut les afficher en #IIIF les exports sont simples, nous avons même un chercheur retraité qui documente ses images en ligne... bref, à la #MMSH on préfère cette solution plutôt que le bazar de #Nakala ou les sites locaux voués à la #disparition

DINAX hat ein kostenloses Tool veröffentlicht, um auf einfach Weise, Copyright relevante IPTC Daten zu schreiben.

Are there any experiences with IPTC-tags restricting the use of the images for training ML/AI?

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.

The International Puppy and Trainer Contest (IPTC.dog) is back to Chicago! Honored to be working with an awesome team to select the next representatives of the Puppy/Trainer community.

PS. Very impressed by the characters, energy, and accomplishments of this class of contestants!

Is there a tag or keyword that can be put in #exif or #iptc to indicate that an #image shouldn't be used for #AI or other #crawling / mass consumption? #photography #copyright #enshittification

TIL there is something called IPTC IIM/XMP

> [ . . . ] Almost all the IIM attributes are supported by the Exchangeable image file format (Exif) [ . . . ]
> IIM metadata can be embedded into JPEG/Exif, TIFF, JPEG2000 or Portable Network Graphics formatted image files. [ . . . ]
> IIM's file structure technology has largely been overtaken by the Extensible Metadata Platform (XMP), but the IIM attribute definitions are the basis for the IPTC Core schema for XMP.

‌en.wikipedia.org/wiki/IPTC_Inf…

Not sure what this means exactly. Is IIM backwards-compatible with EXIF where they overlap? There's a mapping between them?

> XMP can be used in several file formats such as PDF, JPEG, JPEG 2000, JPEG XR, GIF, PNG, WebP, HTML, TIFF, Adobe Illustrator, PSD, MP3, MP4, Audio Video Interleave, WAV, RF64, Audio Interchange File Format, PostScript, Encapsulated PostScript, and proposed for DjVu. In a typical edited JPEG file, XMP information is typically included alongside Exif and IPTC Information Interchange Model data.

‌en.wikipedia.org/wiki/Extensib…

Again I assume this means there is some mapping between the XMP data model and whatever means of adding metadata each of these formats has. And "alongside" ... just means the fields can coexist, or are core XMP fields literally the same mapping as IIM and IIM is to the extent it's possible mapped to existing conventions in the pre-existing namespace for each format?

✍️ Handling IPTC metadata on Android and Windows

It's totally annoying that the Big Five don't support the image metadata format #IPTC, like image processing top dog Adobe and others do. But there are workarounds for #Android and #Windows...

https://kiko.io/post/Handling-IPTC-metadata-on-Android-and-Windows/

I've been diving into the innards of photo file metadata recently for a personal project. Found the IPTC site very interesting for the formal background and definitions.

#tech #photography #iptc

Just released v2023.4.0 of #Photini, a simple #photography #metadata (#Exif, #IPTC, #XMP) editor.
https://photini.readthedocs.io/en/latest/

This version adds "image regions", allowing the user to label parts of a picture. See https://www.iptc.org/std/photometadata/documentation/userguide/#_image_regions for more about image regions.

PS Photini also includes a #Pixelfed / #Mastodon uploader that reuses the metadata that's already been set for each picture.

Un éditeur de métadonnées photo en Python assez complet https://photini.readthedocs.io/en/2023.2.0/ #python #opensource #photographie #iptc #exif #geotag #windows #linux #macosx

@budley Today's deep investigations of #IPTC standards reveal they have an entire vocabulary for different sorts of image regions. https://cv.iptc.org/newscodes/imageregionrole/
One of these will be appropriate for storing the centre about which an image should be cropped, which is all I need for my #pixelfed uploader.

Je ne l'avais pas noté, mais mon modèle de nom de fichier pour XNViewMP est

One irritating feature of Mastodon is that it strips metadata from posted images. (that it Mastodon is no worse about this than Facebook or Twitter is no comfort)
