This is an old photo, I shoot in 1985. At the time, no digital imaging was available. I used my Canon F1 New camera with a 20 mm 2.8. I do not remember the shooting details. I think I used a quite long exposure time (around 1-4 s) and a close aperture (maybe 11-16). I love this picture as I took in my hometown (Bologna), which is a town with a lot of relics from middle Age. It famous for Porticos as well.
