P: Exporting EXIF with high "Transform" value

I just encountered a weird thing. My website complains with just TWO out of many photos I posted (JPG from LR), that it can't read the EXIF data. Looking with IrfanView, there are no EXIF data in these two (they got exported in one batch with all the others).
I noticed that these two photos are heavily transformed (Vertical -65), whereas all the others, that got some transformation (not all but quite some) don't have such high values and got exported with their EXIF. So. I played around with the vertical value and found out, that the EXIF data gets exported up to the value -39 and from -40 on it's missing. Reproducible.

    Updates to Lightroom Classic, Camera Raw, and the Lightroom Ecosystem were released yesterday and contain a fix for this issue.  Please install the appropriate update and see if it solves this problem. You can read more about the updates here.

    Thank you for your patience.

    Thank you, this is great. So in the end it's just a question of file size, huh?

    We are working on a fix for this. Thank you for reporting this and for providing samples!

    For now, a workaround is to open the photo in Photoshop and save it as a JPEG from there... yes, I know this is not awesome.

    This will be more likely to happen with photos that are square (and square-ish) and have a lot of subject detail. The reason why different transforms make a difference is probably because some end up pushing more detail into the final image bounds than other transforms.

    Thanks for the report. We'll investigate and log bug if necessary.

    It's definitely a bug in how LR is writing the metadata.

    Ah, so it's not just me and my Lightroom 🙂
    Do we see that as a bug that needs to be fixed, or is this a case of "It's supposed to be like that"?

    With JPEGs exported from your sample photo in my LR 9.0, ExifTool shows EXIF data when Vertical = -39 but not when Vertical = -40. 

    The -39 JPEG has two APP13 Photoshop segments, while the -40 JPEG has three.  It appears that the Photoshop Thumbnail field increased in size from 64346 to 64717 bytes between the two photos, just enough to require a third APP13 segment.  It's likely this third segment is related to LR getting confused and omitting or overwriting the APP1 segment containing the EXIF fields.

    Um, I don't have any dropbox thing, so I zipped the two files and uploaded it to my server.

    For sharing the photo and the xmp, you could use the Creative Cloud sync or other dropbox style sharing service and share the link.

    It's not about the ftp. I can reproduce the behaviour by just exporting the picture as JPG to my disk and look at it with IrfanView.
