What are incident light meters?
Incident light meters are devices used to measure the intensity of light falling onto a subject being photographed.
Unlike reflected light meters, which measure light reflected off the subject, incident light meters provide a direct measurement of the illumination reaching the subject.
Components of an incident light meter:
A typical incident light meter consists of a light-sensitive sensor or cell housed within a protective dome.
The photographer points the meter towards the primary light source, ensuring that the dome receives the same illumination as the subject.
The meter then calculates the appropriate exposure settings based on the intensity of the incident light.
Here is a quick breakdown of incident light meter components:
Light-sensitive sensor or cell:
At the core of an incident light meter is a light-sensitive sensor or cell responsible for detecting the intensity of the incident light.
This sensor is designed to accurately measure the amount of light falling onto the subject being photographed.
Protective Dome:
The sensor or cell is typically housed within a protective dome or diffuser, which serves to shield it from direct exposure to light and to provide an even distribution of light during measurement.
The dome ensures that the sensor receives light from all directions, mimicking the illumination reaching the subject.
Meter Body:
The meter body houses the sensor, controls, and display screen. Its ergonomic design makes it easy for the photographer to hold while using it.
The body of most models features some buttons or dials for adjusting settings such as ISO, aperture, and shutter speed.

Most of the incident light meters include a display screen to show exposure information such as aperture and shutter speed settings, as well as additional data such as ISO sensitivity and exposure compensation.
This screen allows photographers to easily view and adjust exposure settings based on the meter’s readings.
Controls:
Incident light meters typically feature controls for adjusting settings and modes, allowing photographers to customize the meter’s operation according to their specific shooting requirements.
These controls may include buttons, dials, or switches for selecting ISO sensitivity, metering mode (e.g., incident or reflected), and exposure compensation.
Power Source:
Batteries power incident light meters, providing the power necessary to run the sensor, display screen, and other electronic components. Battery life varies depending on factors such as usage frequency and the type of batteries used.
Connectivity Options:
Some advanced incident light meters may offer connectivity options such as USB, WiFi, or Bluetooth, allowing photographers to transfer exposure data to external devices such as computers or smartphones for further analysis or processing.
