Abstract
An aqueous developer solution for use in digital film processing. The developer solution includes a developing agent and at least one surfactant or thickener. A method of processing a photographic film is also provided, and includes the steps of coating an aqueous developer solution containing at least one surfactant or thickener onto the film, thereby developing the film, and scanning the film through the coating of developer solution.
Claims52
An aqueous developer solution for use in digital film processing, comprising:
- a developing agent;
- at least one surfactant;
- and
- at least one thickener;
- wherein said developer solution has a surface tension of less than about 30 dynes/cm and a viscosity of between about 5.000 and about 30.000 cP.
A method of processing a photographic film, comprising:
- (a) coating an aqueous developer solution containing a developing agent, at least one surfactant, and at least one thickener onto said film, wherein said developer solution has a surface tension of less than about 30 dynes/cm and a viscosity of between about 5,000 and about 30,000 cP, thereby developing said film;
- and
- (b) scanning said film through the coating of developer solution.
A film processing system comprising:
- a film loader operable to received exposed film;
- an applicator operable to coat 100-10,000 micrometers of a developer solution onto the film, wherein the developer solution includes a developing agents, at least one surfactant, and at least one thickener, and has a surface tension of less than about 30 dynes/cm and a viscosity of between about 5,000 and about 30,000 cP;
- and
- a scanning system operable to digitize at least one image contained on the film and produce at least one digital image.
A method for processing film comprising:
- receiving an exposed film;
- coating 100-10,000 micrometers of a developer solution onto the film, wherein the developer solution comprises a developing agent, at least one surfactant, and at least one thickener, and has a surface tension of less than about 30 dynes/cm and a viscosity between about 5,000 and about 30,000 cP;
- illuminating the film with light;
- measuring a light intensity from the film and producing sensor data;
- and processing the sensor data to produce at least one digital image.
