Photography Concepts

each of the two symbols [ ] used to indicate that the enclosed numbers or words should be considered separately

In mathematical expressions, brackets [ ] are used to group terms or indicate priority in operations.

a camera feature that allows users to capture multiple consecutive photos in quick succession by holding down the shutter button, making it easier to capture fast-moving or action-packed scenes

a specialized photographic lighting accessory that produces a soft, even light with a slightly specular or glossy quality, often used in portrait and fashion photography to create a flattering, glamorous look

a type of electromagnetic radiation that makes it possible to see, produced by the sun or another source of illumination

The room was filled with bright light from the lamp.

a supplementary light used in photography, videography, and filmmaking to reduce shadows or fill in areas that are poorly lit

the coordination of the camera's shutter speed with the firing of an external flash, so that the flash output is synchronized with the opening of the camera's shutter

a photographic phenomenon where the subject's eyes appear red or orange in a flash photograph, caused by the reflection of the camera flash off the retina of the subject's eyes

a measurement of a flash unit's power output and range, calculated by multiplying the distance between the flash and subject by the f-number of the camera's aperture setting

the main source of light used to illuminate the subject of a shot or scene in film or photography

a self-contained photographic lighting unit that combines a flash tube, power source, and modeling light into a single, portable device

a photographic accessory used to redirect or bounce light onto a subject, typically consisting of a flat or curved surface made of reflective material

The bicycle has reflectors on the wheels for safety at night.

informal terms for the nose

a photographic lighting equipment that diffuses and softens studio light to create a more flattering and natural-looking light for a subject

the aesthetic quality of the out-of-focus areas in a photograph, particularly the way that points of light are rendered and appear as soft, blurred circles or shapes

a photographic effect that occurs when the camera's shutter remains open for a longer period of time, causing moving objects in the scene to appear blurred in the final image

a compositional guideline in photography and other visual arts that suggests dividing an image into thirds both horizontally and vertically, and placing the main subject or points of interest at the intersections or along the lines

the extent of the scene that is captured by a camera's lens and recorded in the final image, measured in degrees and determined by the focal length of the lens and the size of the camera's sensor or film

the capacity of a system to reproduce loud sounds without distortion

the technique of representing a two-dimensional object in a way that gives the right impression of distance by drawing objects and people that are farther in a smaller size

The artist used perspective to make the road appear to stretch into the distance.

the space in front of a moving subject that is included in the image frame, allowing room for the subject to move or travel within the frame

a compositional guideline in photography that suggests dividing the image into three triangles by drawing lines from the corners of the frame to the center of the opposite side

a border that surrounds a picture, mirror, etc.

The antique frame around the painting added a touch of elegance to the artwork.

(physics) the degree to which a substance is compacted, measured by dividing its mass by its volume

The density of water is approximately 1 gram per cubic centimeter (g/cm³).

differences in color or in brightness and darkness that an artist uses in a painting or photograph to create a special effect

The painting used a stark contrast between light and shadow to create a dramatic effect.

a condition in which two people, groups, or countries give each other mutual help or advantage

the condition of being unprotected from harm, danger, or adverse conditions

Prolonged exposure to the sun can cause burns.

the length of time that the camera's shutter remains open to allow light to enter and reach the camera's sensor or film

the opening in a camera's lens that controls the amount of light that enters the camera and reaches the sensor or film

She widened the aperture to f/1.8 for a blurred background in her portrait.

a numerical measurement that represents the size of the lens aperture and determines the amount of light that enters the camera

a visual artifact that occurs in digital photography when a fine, repetitive pattern in the subject, such as a fabric or a grill, interacts with the camera's sensor and produces an unintended, wavy pattern in the final image

a common optical aberration that occurs in photography when different colors of light are refracted differently through a lens and fail to converge at the same point

the extent of the scene that is visible through the camera's lens and recorded in the final image

the act of directing your attention and energy toward a particular thing or task

She needed to maintain her focus during the exam to ensure she answered all the questions accurately.

the technology or mechanism in a camera or other optical device that automatically focuses on the subject being photographed or viewed

The new camera’s autofocus system is incredibly fast, making it perfect for capturing action shots.

the range of distance in a scene that appears acceptably sharp and in focus in the final image

the range of distance in a scene that is in focus at a specific camera-to-subject distance and lens aperture setting

the closest distance a lens can be focused at a given aperture setting while still keeping objects at infinity acceptably sharp, and is useful for maximizing the depth of field in landscape

a change for the worse

the range of all types of electromagnetic radiation, including radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays, ordered by wavelength or frequency

the distance between the lens and the camera's sensor or film when the lens is focused at infinity, measured in millimeters, and affects the angle of view, magnification, and depth of field of the final image

the unintentional darkening or shading of the corners or edges of an image, caused by factors such as the lens design, the use of filters or lens hoods, or the angle of light entering the lens

a camera setting that allows the user to adjust the camera's exposure settings

a numerical representation of the camera's exposure settings, calculated by combining the aperture, shutter speed, and ISO sensitivity values into a single value

the range of exposure settings that a camera's sensor or film can capture while still producing an acceptable level of image quality and detail

a photographic technique developed by Ansel Adams and Fred Archer that involves a methodical approach to exposure and development to achieve the desired tonal range and contrast in the final image

a camera setting that determines how the camera measures the light in a scene to set the exposure settings

the smallest unit of an image on the screen that collectively can form a whole image

a type of image file that uses lossless compression to reduce file size without compromising image quality

a type of image file format that uses lossy compression to reduce file size by discarding some image data

a type of image file format that uses lossless compression to reduce file size without compromising image quality

a type of image file format that stores digital images as a grid of pixels, with each pixel represented by a specific color or shade

the scientific study of the photographic properties of light-sensitive materials

the adjustment of colors in a photographic image to ensure that they appear natural and accurate, with no dominant color cast or tint
