The Pullen Collection, consists of a number of radiographs of historical importance, marking the first radiography of operational gas turbines.
These film radiographs have been digitised using a Kodak LS85 Film Digitiser at 254dpi (0.1mm per pixel) to provide 12-bit images. For the purposes of this website, the 12-bit images have been contrast stretched, before conversion to 24-bit colour (8-bit grey scale).
All the radiographs, with the exception of the two cold neutron radiographs are 14" x 17", which have a digitised size of approximately 3500 x 4200 pixels. The cold neutron radiographs are smaller (12" x 15.5") and have a digitised size of 3000 x 3900 pixels. All the radiographs are copies of the originals, which were exposed over 30 years ago.
