Many symmetrisations of a single hand radiograph of a patient suffering from rheumatoid arthritis.

The image was infact a dia-positive of that particular hand radiograph,
and was prepared by an old professor of orthopedics and traumatology
to be shawn in a lecture about rheumatoid arthritis (RA).
Then, after the retirement of that professor, the image passed to
his son, who also worked in the same department as an associate
professor.

It was in this associate professor's lecture on RA that I first saw
this image and was struck by it (it was 1996, as far as I remember)...
After the lecture, I asked for permission to borrow the transparency
for being able to enlarge and print it in our photography club in the
faculty.
I had the symmetrisations in my mind from the very beginnign,
but I had to wait to own a computer and a scanner for being able to
produce them seamlessly...

Well, talked too much, but I cannot resist to remember and tell the
stories... :)
