Flash duration
The length of time the flash emits light during a single burst, often measured in fractions of a second.
Flash metering
The process by which the camera measures the amount of light needed for proper exposure when using flash.
Flash sync speed
The fastest shutter speed that can be used when using flash photography to synchronize the flash with the exposure.
Flash
A burst of artificial light used to illuminate the scene, particularly in low-light situations.
Flat light
Lighting conditions that lack strong contrasts, often resulting in a low dynamic range and less pronounced shadows.
Flatbed scanner
A device used to scan physical photographs or documents and convert them into digital files.
Fluorescent lighting
Artificial lighting that emits light through the excitation of phosphors, commonly found in offices and commercial settings.
Fly-on-the-wall
A documentary or candid photography style where the photographer remains unnoticed, capturing natural and unposed moments.
F-number scale
The sequence of numbers representing different aperture sizes, typically displayed on the lens barrel.
F-number
The numerical value representing the size of the lens aperture opening, determining the amount of light entering the camera.
Focal distance
The physical distance between the lens and the subject being focused on.
Focal length
The distance between the lens and the image sensor, affecting the field of view and magnification of the subject.
- 18mm = wide angle
- 50mm = normal view
- 200mm = zoom/telephoto
