A low volume photographic material processing apparatus that utilizes a narrow horizontal processing channel with an upturned entrance and exit to contain processing solution within the channel. A replenishment pump calibration system is integrated into the processor so that no manual measurements or special tools are required to set replenishment solution rates.

A low volume photographic material processing apparatus that utilizes a tank having integral means through which processing solution is pumped and a rack which has integral means to facilitate its insertion and removal from the tank, the rack and the tank are relatively dimensioned so that a small volume for holding processing solution and photosensitive material is formed between the rack and the tank. The apparatus accurately maintains the processing solution level by keeping the upper surface of the processing solution below the high impingement devices solution exit.

An apparatus and method for printing a color image from a photographic transparency onto a photosensitive medium is claimed. A plurality of light sources each provide light of a different color when energized. The different color light of each light source has a light intensity level established by an energizing level applied thereto. A light integrator combines the different colored light from the light sources to produce light of a composite color along a primary optical path. The photographic transparency is disposed along the primary optical path such that the composite color light passes through the photographic transparency and produces a projection of the color image from the photographic transparency. An electronic imager is provided for imaging the projected color image of the photographic transparency. A device is provided for exposing the photosensitive medium with the projected color image. A power supply is provided for energizing the plurality of light sources. The power supply provides a first plurality of predetermined energizing levels to the plurality of light sources respectively to produce a first composite color light that substantially compensates for the sensitivity response of the electronic imager. Alternately, the power supply provides a second plurality of predetermined energizing levels to the plurality of light sources respectively to produce a second composite color light that substantially compensates for the sensitivity response of the photosensitive medium.

Color image reproduction with compensating light source

Apparatus for detecting the presence of processed photograph film at a particular location comprises a light source which emits green or blue light having a wavelength in the range of 420-600 nanometers. A light sensors positioned to receive light from the light source when the film is not present. An infrared filter and a filter for transmitting light in the range of wavelengths emitted by the light source are positioned in front of the light sensor.
