An apparatus, and a method, of mounting a transparency (13), for scanning, on a drum (1) of a rotary drum scanner are described. The apparatus comprises: a liquid dispenser (8) arranged to dispense liquid in the drum (1) arranged such that rotation of the drum (1) at sufficiently high speed causes liquid to move over a surface of the transparency (13) to form a film of liquid thereon and wherein the transparency (13) is located against the inner surface of the drum (1). Preferably the liquid dispenser (8) comprises a liquid reservoir (8) which is locatable on the inside of the drum (1) and is conveniently in the form of an annular channel (9) arranged coaxially within the drum (1). To prevent liquid from escaping from the drum (1) when it is being rotated, the apparatus further comprises a liquid stop (5) which is conveniently in the form of an annular channel (7) arranged coaxially within the drum (1).
