SENSITOMETER Meaning and
Definition
-
A sensitometer is a device or instrument employed in photography or printing industries to measure the sensitivity or response of a photographic emulsion or film. It assists in characterizing and calibrating the parameters of photographic materials, such as speed, contrast, and tonal range.
Typically consisting of a series of precisely calibrated steps or exposures, a sensitometer exposes a photosensitive material to controlled amounts of light through a step wedge or set of test targets. This step wedge usually consists of numbered density steps that vary in intensity, from very light to very dark. By exposing the material to different known light levels and measuring the resulting densities, a sensitometer provides a quantitative assessment of the material's sensitivity and its ability to record various degrees of brightness.
The sensitometer's primary objective is to determine the film or paper's characteristic curve. This curve shows the relationship between the amount of light received by the material and the corresponding density it produces. The sensitometer helps photographers and printers understand how the material will respond to different levels of illumination, allowing them to make adjustments for optimal exposure and processing.
Sensitometers are essential tools for the quality control and standardization of photographic materials, ensuring consistency and reproducibility in the final images produced. They play a crucial role in research, development, and manufacturing processes related to photographic emulsions, films, plates, and papers.

Etymology of SENSITOMETER
The word "sensitometer" is derived from two root words: "sensito-" and "-meter".
1. "Sensito-" comes from the Latin word "sensus", meaning "sense" or "feeling". It is also related to the Latin verb "sentire", which means "to feel" or "perceive".
2. "-Meter" is derived from the Greek word "metron", meaning "measure" or "meter".
Combining these roots, "sensitometer" literally means a device or instrument used to measure or quantify sensitivity or perception. The term is commonly used in relation to photography and film to describe an instrument that measures the sensitivity of photographic materials to light.
