SENSITOMETERS Meaning and
Definition
-
A sensitometer refers to a device or tool used in the field of photography to measure the sensitivity or speed of light-sensitive photographic materials, such as films or papers. It is specifically designed to gauge the response of these materials to light by systematically exposing them to a series of standardized light exposures.
The sensitometer typically consists of a light source, a series of filters, and a mechanism to control the duration of exposure. The light source emits light with a known intensity and spectrum, while the filters are used to vary the intensity of the light exposure. The duration of exposure is controlled to provide a range of exposure levels.
By exposing a photographic material to gradually increasing light exposures, a sensitometer can generate a characteristic curve that represents its response to light. This curve, commonly called an H&D (Hurter and Driffield) curve, helps evaluate the performance of the material, such as its sensitivity, contrast, and tonal range.
Photographers and photographic laboratories utilize sensitometers to measure the speed or sensitivity index of different films, papers, or other light-sensitive materials, aiding in quality control and providing a reference for reproducing accurate and consistent exposures. Additionally, sensitometers are also employed in the field of scientific research to study the sensitivity and behavior of photographic emulsions or other light-sensitive materials.

Etymology of SENSITOMETERS
The term "sensitometers" is derived from two words: "sensitometer" and "-s" (denoting plural form).
The word "sensitometer" comes from the combination of two roots: "sensito-" and "-meter".
1. "Sensito-" is derived from the Latin word "sensus", which means "sense" or "feeling". Here, it refers to the concept of sensitivity or responsiveness.
2. "-Meter" comes from the Greek word "metron", meaning "measure" or "measurement".
Combining these, "sensitometer" can be understood as a device used to measure sensitivity.
To form the plural, "-s" is added to "sensitometer", resulting in "sensitometers". This is a common practice in English to indicate the plural form of a word.
