ABSTRACT:
Factors affecting the quality of the development of a photosensitive material include the characteristics of a processing fluid flow in contact with the material. A uniform turbulent fluid flow is created in a photographic processing apparatus by utilizing the height of the fluid in a tank for retaining the processing fluid. The height of the fluid creates a fluid pressure which is utilized in determining the flowrate of the fluid in the processing apparatus. An uncomplicated, low friction fluid flow is also created which allows for a more efficient, lower cost photographic processing apparatus.
