I am trying out some of the new features of PWP 8.0. I would like to take a jpeg image, with laboriously incorporated metadata, crop and downsize and sharpen for web display, yet keep all the jpeg's original metadata, including GPS, IPTC, and EXIF information. Is this possible? What is the best way to do this?

Thanks,

Normally all the metadata is preserved by transformations such as Resize and Sharpen, etc. Are you having a problem with some of the metadata being lost?

Jonathan,

Thanks for the response. I created a small image, added various metadata to it with a metadata editor (Daminion 5.8), then went into PWP8 Alpha 20-Jan-2019, opened the file and performed a single sharpening transformation "Sharpen/Sharpen More", then saved the result. The sharpened image lost its exif tags. IPTC information (e.g., location), and "Makernotes". Is this what you would expect? Shall I make the files and workspace script available?

Much of the camera information was preserved, including shooting parameters and GPS data. (The old PWP7 mangles the shooting information.)

Thanks,

Well, the metadata topic is a mess. There are many different kinds of metadata (formats, structure,purpose). For some metadata groups there are different versions. For example IPTC. To my opinion the "xmp-standard" for metadata is important and should be supported in a way that the xmp-metadata are not lost. I don't see a need for PWP to implement a metadata editor.
I guess Daminion 5.8 supports this "xmp-standard" as well as Imatch does.
Some stuff to read http://www.photometadata.org/#

I'm not sure what you mean when you say the EXIF tags are lost but much of the camera information was preserved, since the camera information is stored in EXIF tags.

What about just opening and saving the file without sharpen. Does that also mess up the metadata?

Jonathan,

Yes, opening and re-saving a file also drops the metadata I am looking at. By "Tags" I mean what the Windows Explorer window shows under that field. They are stored both as a part of EXIF (as "XP Keywords" using exiftool to view), and as a part of IPTC as "Keywords" (using Metadata++ to view).

Thanks, that was a good idea.

OK, if you give me a list of a few specific tags that are getting lost I can try to figure out what is happening to them.

Jonathan,

Here is a screenshot. File RBW (1824).JPG is an original jpeg output form Canon's DPP software. I opened it in PWP 8 by dragging it to the workspace. I then saved it using the "Save as" widget, generating the RBW (1824) v1.jpg file.

I then right click on each file in a Windows explorer window, select "Properties" and see what it says in the Details tab for each file. The Before/After windows show that The "Title" field has been replaced with the Description field. The Ratings field has been removed. The Tags field has been removed. Everything else I check seems to have been preserved.

Thanks,
Bob W

It looks like the screenshot image got downsampled to where it is unreadable. Here are two images, just of the properties dialogs.

For checking metadata I use (and trust) the exif tool.
The files are text files and zipped for uplaod reasons.
