Photographic Densitometer

A photographic densitometer is a device used to measure the darkness or opacity of photographic or printing materials, such as films, prints, or foils. It works by shining a controlled light through or onto the material and measuring how much light is absorbed or transmitted. The device then calculates a density value, indicating how dense or transparent the material is. This measurement helps ensure the quality and consistency of photographic processes, aiding technicians in controlling exposure, development, or printing to achieve the desired image quality.
