Electronic Shutter (n.) is a digital method of controlling exposure time by electronically switching the camera sensor on and off to capture light, eliminating the need for physical moving parts found in mechanical shutters. All smartphones and most action cameras…
EXIF (n.) Exchangeable Image File Format – metadata automatically embedded in your photos that records detailed information about how, when, and where each image was captured, including camera settings, GPS coordinates, device model, and editing history. This invisible data travels with…
Exposure (n.) The total amount of light that reaches your camera sensor during a single capture, determined by three variables: aperture, shutter speed, and ISO — collectively known as the exposure triangle. Too much light and your image is overexposed…
Exposure Compensation (n.) A manual adjustment that tells your camera to make the next photo brighter or darker than what it would have chosen automatically. Measured in stops, usually from -2 to +2, with each full stop doubling or halving…
Exposure Triangle (n.) The fundamental relationship between three camera settings that control exposure: aperture (how wide the lens opens), shutter speed (how long the sensor is exposed), and ISO (how sensitive the sensor is to light). Change one, and you…
Filter (n.) A device or digital effect that modifies light before capture or alters an image during editing. In mobile and action photography, the term covers two distinct concepts that are easy to confuse but completely different in practice. First,…
Flash (n.) A built-in LED light on your phone that fires a brief, intense burst of illumination to light up dark scenes. Most phones include a small LED flash (or dual-tone LED on flagships) next to the rear cameras, and some…
Focal Length (n.) The distance in millimeters from a lens’s optical center to the sensor when focused at infinity, determining field of view and magnification. In mobile photography, actual focal lengths are tiny (typically 2-9mm due to small sensors) but expressed…
Focus (n.) The specific plane of sharpness in an image where light rays converge precisely on the camera sensor, with objects at that distance appearing crisp while nearer or farther elements blur according to depth of field. In traditional cameras, focus…
FOV (Field of View) (n.) The extent of the observable scene captured by a camera lens, measured in degrees. A wider FOV captures more of the environment in a single…
FPV (First Person View) (n.) A filming perspective that places the camera at eye level or mounted directly on a moving subject, simulating the experience of being there in person.…
Frame Rate (n.) The number of individual frames (images) captured per second in a video, measured in fps (frames per second). Common frame rates are 24fps (the classic cinema look),…
Framing (n.) A compositional technique where elements at the edges or corners of the frame — archways, windows, tree branches, car doors — partially surround the main subject and direct attention toward it. It’s one of the oldest tricks in…
Front Camera (n.) The camera mounted on the screen side of your smartphone, facing you when you hold it normally. Also called the selfie camera, it typically has a smaller sensor and simpler lens than your rear cameras—usually a single fixed…
Geotagging (n.) The process of embedding precise geographical coordinates into a photograph’s metadata, effectively pinning the image to a location on Earth. Every geotagged photo carries latitude, longitude, and often altitude data tucked inside its EXIF header. For phone photographers,…
A stabilization device.
Golden Hour (n.) — the window of soft, warm light roughly the first and last 60 minutes of daylight. The sun sits low on the horizon, which means light travels through more atmosphere, scattering the blue wavelengths and leaving reds,…
Grid Lines (n.) A composition overlay consisting of horizontal and vertical lines dividing the camera viewfinder or screen into nine equal sections. Also called a rule-of-thirds grid, this is the most widely available composition aid in mobile photography. What Grid…
Haptics (n.) Tactile feedback technology that simulates touch sensations through vibrations, precise motor forces, or subtle motions. In mobile photography, haptics transforms how you interact with your camera app, replacing visual-only feedback with physical confirmation you can feel through your fingertips.…
HDR (High Dynamic Range) (n.) A photographic technique that captures and combines multiple exposures—typically three or more—to preserve detail in both bright highlights and deep shadows within a single image. In mobile photography, HDR operates as an automated computational process that…
