How to see embedded face data outside Tonfotos

Marleen9

Hello, I’ve been happily working with Tonfotos for quite some time. I really appreciated the update where the face data was written into the file’s metadata. I’m just wondering where I can actually find that, for example in another program. I see that it’s not stored as a keyword. So how does that work? Thanks in advance!

Andrey

Marleen9 Well, this forum is about Tonfotos, so I hope you can understand we don’t provide detailed support for other applications here. However I can name some of them that you can use to check if the face metadata is there. My personal go to tool for anything for photo metadata is exiftool, but this is a console utility so it is not for everyone. Alternatively you can use Faststone image viewer, it will not only show you the metadata, but can actually display embedded face regions. Both apps are free.

I completely understand that. My question wasn’t so much about other programs, but more about the technical aspect of how such information is stored. But I now understand that it’s probably stored in the XMP data.

Andrey

Marleen9 That is correct, XMP is the only metadata type that is capable of storing faces information. Neither EXIF or IPTC have fields for that.

Hello, does this mean (English is not my language) that there is no way to store the name in the file as a keyword to be recognized by Windows or macOS? I was thinking of using your software instead of Lightroom but if you can’t exploit the files from the keywords, that poses a serious problem. I do not speak about faces informations but only about the name of people in the, photo.

Andrey

Camco Tonfotos stores face information that includes person name. You can also add any tags you want, tags can be people names. Tags will be recognized by most programs.

Camco

Hello Andrey, this you for this quick answer, are we talking about the same tags ?
I’m talking about “keywords” “mots clés” the one you can see in the pictures I upload (macOS and windows).
How can you get them ? Do I need to export the files ?

Andrey

Camco Well, there is not much I can tell just by looking this this screenshot. Most likely yes, those will be compatible, but just to be sure I would propose to check one of those files by Tonfotos to see if it recognizes those as keywords as well and can edit them.

Camco

We’re having trouble understanding each other, :-). My problem is not in this way.
My question is: After using Tonfotos to identify people, how do I find their names in the Windows keyword columns? How do I save the names before exiting Tonfotos? Currently, I can only find names using Tonfotos. With Lightroom, I have a “Save metadata to files” function. Is there something equivalent in Tonfoto? Bonne journée

Andrey

Camco Ah, I see, thank you. For tags, you don’t need anything, they will be saved immediately. For faces, you need to turn on saving in the settings: https://community.tonfotos.com/d/535-version-1105-saving-person-data-in-xmp Saving poeple data takes some time and is done in backgroud, so you should way couple minutes after making changes.

Camco

Sorry, but no. Look at Screenshot I upload. I would like the name of the recognized face to appear on the XPKeywords line (where there is “2023”)…
Est ce possible ?

Andrey

Camco XPKeywords

No, Tonfotos does not modify this field.

Why you expect people names to end und up there? Those are people names, not keywords.

Camco

Are you an IA ? Sorry but you seem to not know what you are talking about… Of course this is keywords. Those with which you can search and classify without the use of software, just with the windows explorer or the Apple finder… I do that since years.
Your soft is one of the best for facial recognition, But if I can’t then exploit this work outside your universe, it’s not of great interest.
regards

Camco As I said, currently, we don’t do anything with the XPKeywords field, however we save proper face information where it is supposed to be, in regions. This is standard way, not Tonfotos-specific that exists only in Tonfots universe. Pretty much any other software that deals with people on photos will read and understand this.

Windows explored however, does not read this data, AFAIK, but it reads keywords and can search using them. In theory, we can also populate XPKeywords with people names to increase compatibility. I would suggest you to submit this as feature request in separate thread, and if more people will be interested, we will add this to the roadmap.

Camco

Good news, thank you for all that.
