Abstract
A method for reforming the surface of a photographic emulsion layer. In the method, the surface of the emulsion layer is dried to at least sensible dryness. Water is then deposited onto the surface of the emulsion layer. The depositing is substantially uniform and in an amount that is less than about 0.80 grams of water per square foot of emulsion layer.

A method for reforming the surface of a photographic emulsion layer comprising the steps of:
- drying the surface of said emulsion layer to a predetermined dryness;
- depositing water onto said surface of said emulsion layer, said depositing being substantially uniform and in an amount that is less than about 0.80 grams of water per square foot of said emulsion layer.
A method for reforming the surface of a photographic emulsion layer comprising the steps of:
- condensing water onto the surface of said web, at a substantially uniform volume of from about 0.10 grams of water per square foot of surface to about 0.4 grams of water per square foot of surface;
- allowing at least a portion of said condensed water to bond with said substrate;
- and
- vaporizing any remaining free water from said surface.
A method for conditioning a photographic substrate, comprising the steps of:
- condensing water onto at least one surface of said substrate in a first treatment zone, said condensing being at a substantially uniform volume of from about 0.1 grams of water per square foot of surface to about 0.4 grams of water per square foot of surface;
- allowing at least a portion of said condensed water to bond with said substrate;
- vaporizing any remaining free water from said surface in a second treatment zone;
- and
- transporting said substrate sequentially through said zones.
