OT: Cool photos! Michael, what lens
did you use? An 8mm? If you don't
mind me asking.

ffprobe reports:

But I guess we already knew that from
your error message as Moritz said!

If you wanted to convert it back this
could work?

$ ffmpeg -i IMG_044.JPG -pix_fmt yuvj422p IMG_044-yuvj422p.JPG

The resulting difference is almost invisible:
(I promise it's not all black)
