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

زاویه دید

the space between the top of the subject's head and the top edge of the image frame, and is an important compositional element that can affect the balance and aesthetic appeal of the image

میزان فضای بالای سر سوژه (عکاسی)

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

ژرفانمایی (هنر)

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

فضای در جهت حرکت سوژه

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

مثلث طلایی

the technique of using elements within the scene, such as natural or man-made structures, to surround or enclose the subject and draw the viewer's attention to the main focal point of the image

the amount of light that is allowed to pass through a photographic filter or film, typically measured in stops or optical density units

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

کنتراست

the connection between the intensity of light and the time during which light is exposed to something in photography

ضریب شوارتزشیلد

the amount of light that enters a camera's sensor when taking a photograph, which is determined by the combination of three factors: aperture, shutter speed, and ISO sensitivity

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

سرعت شاتر

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

اپرچر

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

ضریب اف

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

طرح مویر

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
