Okay, Christmas eve, much to do, busy busy busy, but I just received this delightful e-mail from the Solstice photographer. We were fixated on a Virtual Theoretical Photograph. Our Photographer-on-the-Ground in Roma was stuck with the problems of having to take a Real Practical Photograph with a Real Practical Camera, Lenses, Filters, Landscape, etc.
Notice particularly, however, that to get equal spacings between suns, he did NOT use equal times!
Shots were taken using an increasing exponential interval time between each and the other till the Sun maximum height, similarly decreasing till the Sunset.
Now THAT computation must be a NIGHTMARE!
Merry Christmas / Buon Natale everyone!

Sorry for the bad English.

Sorry for the bad English.
The picture "The Winter Solstice" it's a mosaic of 3 multiespositions images of sun, it's made during the winter day solstice.
This image has been studied a lot of time before its realization.
The image is the mosaic of three single shots (A-B-C) taken with a Fuji Velvia 50 ISO film slides, with an only camera of format (120) 6 x 7cm with, focal lens 65mm.
The choose to take three shots was dictated by to cover the entire daily Sun pat from the dawn to the sunset, and also because no exists optics able to cover an angle of 120° (on the long side) without any side distorsion.
Shots were finally stitched in a panoramic view with a normal image processing program.
The sun pat cover the apparent field of around 120° (latitude site = +42°), and a total of 43 single shots have been made on the three mosaic images (someone is hidden from the cloud to the sunset).
Shots were taken using an increasing exponential interval time between each and the other till the Sun maximum height, similarly decreasing till the Sunset. In each single image one shot was taken exposing with a longer time in order to have a "brighter" sun. The other shots of the weak Sun have been made with 2 filters neutral density (Kodak ND 2 and 3) according to the height of the Sun. The light of the 3 bright Suns has illuminated every some three landscapes (images in enclosure).
The landscape is the Tyrrhenian Sea cost of Italy, from "Fiumicino" to "Santa Severa" cities, with the sun that rise just back the city of Rome, that it is hardly visible on the left side of the picture. The original file is 556Mb 16/bit color!

Ciao Danilo Pivato,
Your bad English? You should hear my terrible Italiano! Also my professore at New York University did not tell us that he was giving us a Special Extra Free Gift: his Siciliano accent. This has caused me a few problems.
Grazie encore for the technical explanation of the beautiful photograph. As you can clearly see, Amy the biochemist and I are better astronomers than we are photographers.
Do you know what a Ph.D. Camera is? Ph.D. = Push Here, Dummy. That is the kind of camera I have.
It is Christmas Eve and I have many tasks to do for my wife, so I can't write much. But grazie for a beautiful Solstice gift and a fascinating Christmas gift from Italia! I wish you and your family and friends the very happiest Christmas and New Year! Christmas in Roma must be very magical, I envy you.
In my Sicilian accent: Buon Natale!

It is frustrating when your camera can't take the actual beauty of the city when it is utmost required to cherish the memory. You have to spend huge amount on the camera if you are a tourist and want to capture the images of the biggest attractions of the places you visit. Thanks for sharing the informative article. I'm off to Italy soon. I suggest every tourist of Italy should have Italy Road Map to make their journey great.
