Processing photographic material

Apparatus for processing a photographic material comprising a chamber adapted to hold the material therein, means for introducing solution into the chamber, means for removing the solution from the chamber and means for rotating the chamber, the chamber being made of a material having a thermal conductivity greater than 1.47×10−3 Watt/cm/degree K and the cross-section of the wall of the chamber being substantially uniform throughout.

Apparatus for processing a photographic material comprising a chamber adapted to hold the material therein, means for introducing solution into the chamber, means for removing the solution from the chamber and means for rotating the chamber, wherein the cross-section of the wall of the chamber is such that overall uniformity of temperature is maintained across the chamber.

A method of heating a processing chamber to an operating temperature, the chamber being located within an insulated housing, the method comprising the steps of heating the air within the insulated housing, directing the heated air in a direction away from the chamber, circulating the heated air throughout the housing and rotating the chamber within the heated air, the chamber thus being heated to a uniform temperature throughout.
