Yes. I use Claude Code to help find bugs and draft the fixes, then I review every change myself, check that the new test fails without the fix, and run the full test suite locally before opening a PR. Happy to adjust anything, or close any you'd rather not take. |

exif.get_ifd(ExifTags.IFD.Interop)andget_ifd(ExifTags.IFD.MakerNote)raisedKeyErrorwhen the image has no Exif IFD, or an Exif IFD without that entry, which is most images (151 of the test images). A missing Exif, GPSInfo or IFD1 IFD already returns{}through thesetdefaultat the end ofget_ifd(), as does a truncated MakerNote..get(), and parsing is skipped when it is absent, so these return{}too.
