IPTC Again

Martin312
I have some IDs3 raw files that I have been using to test C1 Pro 4.5d and a couple have IPTC text in them Caption/Keywords/Copyright Notice.

When I convert the same image:
    16 bit TIF: includes the keywords but some applications cannnot see the caption - PS CS2 can/ Fotostation 5 Pro cannot
    JPG (low quality): everything can see the caption but there are no keywords


What is happening ? It is not that C1 cannot cope with the text embedded in the RAW as it uses it some of the time! I usually go via 16bit TIF for cleaning etc in PS and then convert to JPG for library purposes. But occasionaly for web use or other purposes I go straight to JPG.

There seem to be inconsistencies all over the place. I really am trying very hard to be able to use it but every time I have solved a problem a new one slaps me in the face.

    Different programs have different levels of support for EXIF/IPTC. It is hard to say for certain who's at fault without a close look at what is really in the file.

    I mentioned it before ExifTool by Phil Harvey is probably the best piece of software written for examining/editing metadata attached to photos (or just about any file which supports metadata). It isn't a nice GUI-based program, but it is incredibly powerful.

    If you download the ZIP file from Phil's home page: http://www.sno.phy.queensu.ca/~phil/exiftool/ and extract the executable to your desktop, it's default setting is to just display the metadata of any file dragged onto the icon.

    You can check your various TIFF or JPEG files to see what all (and I do mean all) they contain. That way you'll be able to say for sure where to place the blame.

    Thanks, I will do that but it is that the output from C1 that is inconsistent! Alsoit is the IPTC data I am concerned about not EXIF.

    The tool's name is just a legacy thing, it handles just about any metadata on any file type. EXIF, IPTC, even ID3 on MP3s.

    It very well may be that Capture One is inconsistent, but I've seen across many programs their level of metadata support varies from file format to file format. Some can read it in JPEGs, but not TIFFs or the other way around. ExifTool has always shown what is really there.
