A few months ago I recorded in one night two frescoes by Giovanni da Módena in the cathedral San Petronio in Bologna (Bolonia), Italy.
The recording was made by myself and Gabriel Scarpa for Factum Arte.
We used two Clauss Panoramic robot heads, one for a Canon 7D coupled with a 600mm lens and the other for an Elinchrom 1/1000 s flash head.
I processed the files at 400dpi 1/1 in PTGui Pro resulting in files of approximately 80000×90000 pixels so 7 Gigapixels, at 16 bits.
The high resolution image viewers:
San Petronio – Giovanni da Modena – Living Cross – Croce Brachiale
San Petronio – Giovanni da Modena – Verdant Cross
