ISO SPEED Meaning and
Definition
-
Iso speed, short for International Organization for Standardization speed, refers to the measurement of a camera's sensitivity to light. It determines the camera sensor's ability to capture images in various lighting conditions by controlling the amount of light needed for proper exposure. ISO speed is an important component of the exposure triangle in photography, which also includes aperture and shutter speed.
ISO speed is represented by a numerical value, such as ISO 100, ISO 200, ISO 400, etc. The lower the ISO number, the less sensitive the camera sensor is to light, requiring brighter conditions for optimal exposure. On the other hand, higher ISO numbers indicate greater sensitivity to light, allowing the camera to capture images in darker environments.
Manipulating the ISO speed settings enables photographers to adapt to different lighting situations. For example, in bright daylight, a lower ISO setting is chosen for less sensitivity and to reduce noise in the image. In low-light or night-time scenarios, a higher ISO speed is used to increase sensitivity and capture more light. However, increasing ISO speed also increases the presence of digital noise, which is unwanted speckles or grain-like patterns in the image.
In summary, ISO speed is a standard for determining the sensitivity of a camera sensor to light. It plays a crucial role in achieving proper exposure and managing image noise, allowing photographers to adapt to various lighting conditions and capture high-quality photographs.

Etymology of ISO SPEED
The term "iso speed" does not have a specific etymology. However, it can be broken down into two components: "iso" and "speed".
"ISO" stands for International Organization for Standardization, which is an international body that sets standards for various industries. In photography, ISO refers to the sensitivity of the camera's image sensor or film to light. It is a measurement of how quickly the camera detects and reacts to light.
"Speed", in the context of photography, refers to the sensitivity of the camera or film to light. A higher ISO speed means that the camera is more sensitive to light, allowing for faster shutter speeds and better exposure in low-light conditions.
Therefore, "iso speed" in the context of photography refers to the sensitivity setting of the camera or film, which determines the speed at which it reacts to light.
