Question

What is the Adobe jpeg EXIF tag for Description Writer

I'm scanning in lots of family photos and then cleaning them up with my Adobe Photoshop elements app. All photos are stored in JPEG format, hence include EXIF tag information. I read these tags with an app I wrote to display photos the way I want them. When I clean these photos  up, I always include the Adobe EXIF tag called Description Writer. Via an Internet search, I can get the  hex code for almost every EXIF tag, but I'm unable to find the hex code for the tag Description Writer. That's in spite of multiple Internet searches, and speaking with seveal agents at Adobe.

 

Does anyone have a clue as to what the code for this tag is, so that I can read it with an EXIF reader?

    That description writer tag is not an exif data. It's present and available if you open the IPTC section in the information panel of the organizer.

    I suppose it records the name of the software you are running to tag your images. Totally unnecessary if you use the available features from the organizer.

     

    Sorry, the left arrow should point two lines up...  over IPTC status.

    Thank you for the reply Michel! It makes sense that Description Writer is not an EXIF tag. That's why I couldn't find a reference for it. Incidentally, Description Writer doesn't describe the software, rather it notes the person writing the Description part of an Adobe picture.

    But, in summary, this simply opens up another question: how does one get all the Adobe generated IPTC picture tags? I'm looking for a routine that does this for me using Microsoft's Visual Basic .NET. So far, a quick Internet search has shown that this this IPTC tag information isn't easily available for reading and writing, e.g., there are some, but they are unsupported user-written routines.

    After some research and testing, I'm not convinced that the Adobe tag Description Writer is an IPTC tag.

    When searching for a way to read this IPTC data, I came across an article that said you could use the routine JpegBitmapDecoder. So I tried it. Yes, you can get back a list of IPTC codes, but Description Writer is not one of them. Here is the complete list of these IPTC codes returned:

    Application Name
    Author

    CameraManufacturer

    CameraModel

    CanFreeze

    Comment

    Copyright

    DateTaken

    DependencyObjectType

    Dispatcher

    Format

    IsFixedSize

    IsFrozen

    IsReadOnly

    IsSealed

    Keywords

    Location

    Rating

    Subject

    Title

    Shared members

    Non-Public members

     

    So it looks like we need another way to access this tag from a picture file.
