I work near the Sky & Telescope office, and know a number of the editors
since some are in the local astronomy club.
The first analemma picture was taken by Dennis diCicco. He used a 4x5
camera bolted to a window frame, and used an electronic clock timer to
fire the shutter at the appropriate time on the days chosen for pictures.
The picture was made on one piece of 4x5 color film. The first year
he tried this, he didn't take into account the rails that hold the film
in the film holder and cut off a bit of one solar image, so he spent
another year making a second photograph. I saw the camera arrangement
during the secoond year of use.
