PHOTOGELATIN PROCESS Meaning and
Definition
-
The photogelatin process, also known as the collodio-chloride process, is a historic photographic technique that primarily emerged in the late 19th century. The process involves the use of a gelatin-based emulsion that is capable of recording images on light-sensitive surfaces. The term "photogelatin" refers to the combination of photography and gelatin, as the gelatin serves as a binding agent for the light-sensitive substances used in the process.
To execute the photogelatin process, a mixture of gelatin, silver salts, and other chemicals is prepared and applied to a suitable support material, such as glass or paper. This emulsion is then exposed to light through a negative or directly with a camera, capturing the desired image. After exposure, the material goes through a series of chemical treatments to develop and fix the image, making it permanent.
The photogelatin process was widely adopted during its time due to its ability to produce high-quality prints with excellent tonal range and detail. It was extensively used in professional and artistic photography, as well as in industries such as printing and reproduction. However, with the advancement of technology and the introduction of more convenient and efficient processes, the popularity of the photogelatin process gradually declined, ultimately becoming obsolete by the mid-20th century.
Today, the photogelatin process is primarily of historical significance, appreciated for its role in the development of photography as an art form and a scientific tool. It serves as a reminder of the evolution of photographic techniques and the craftsmanship involved in early photographic practices.

Etymology of PHOTOGELATIN PROCESS
The term "photogelatin process" consists of two main parts: "photo-" referring to light and "gelatin" referring to a substance derived from animal collagen.
The word "photo" comes from the Greek word "phōs" (φῶς), meaning "light", which has been adopted into English as a prefix to indicate a connection with light or photography.
"Gelatin" comes from the Latin word "gelatus", meaning "frozen" or "stiffened". The Latin term was derived from the verb "gelare", meaning "to freeze", referring to the solidification process of certain animal and vegetable juices.
The "photogelatin process" is a historical photographic method that involved using gelatin as a light-sensitive material. It was developed in the late 19th century as an alternative to traditional wet plate photography techniques.
