Hi Maureen,

This is likely the underlying OpenSeadragon javascript library picking up on some internal EXIF metadata and adjusting orientation proactively, which we actually don’t want. EXIF data - especially around image orientation - is a nightmare of inconsistency (this example is from a Canon camera, and Canon has its own EXIF metadata as well). For seadragons, we have even seen the EXIF metadata remain but the user rotating images manually, creating an image rotation that is fighting its own EXIF metadata. :frowning:

If we begin to see a lot of this, we can create a ticket and look for consistent criteria for a fix. So far, this seems to be rare.


Hi @jason, I agree, this seems rare enough to ignore. If we see it more regularly, I’ll let you know. Thanks

Um, small bonus points: I can correct the interpretation of the exif data on these. This kind of rotation was only an issue for a couple of weeks and should be fixed, so let me know if you come across more and I’ll get them right-side up. (You may need to refresh the page to see it corrected)

You definitely get bonus points for that! This was the first example we’ve seen so hopefully that’s it for us. It’s not a big deal tho. Thanks!

Hi @tanyastere - we’ve found another 4 examples of this issue on the following encounters. Would it be possible for you to fix them as you did on the example in this report? Pretty please??? thank you!
