Arte e Artigianato - Concetti di fotografia

the technique of taking multiple shots of the same scene with different camera settings, typically exposure, to ensure at least one of the shots captures the desired result

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

a photographic accessory that fits over a studio light or flash unit to create a narrow, focused beam of light

snoot, accessorio per luce

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

softbox, cassa di luce

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

bokeh, sfocato estetico

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

sfocatura di movimento, effetto di movimento sfocato

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 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

spazio sopra la testa, margine superiore

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

prospettiva

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

spazio di guida, spazio di movimento

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

triangolo d'oro

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

inquadratura, incorniciatura

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

densità, opacità

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

contrasto

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

reciprocità

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

esposizione

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

velocità dell'otturatore, tempo di esposizione

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

apertura, diaframma

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

numero f, f-stop

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

motivo moiré, effetto moiré

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

aberrazione cromatica, aberrazione di colore

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

the sharpness and clarity of the subject in an image, achieved by adjusting the camera's lens to bring the subject into clear and sharp focus

fuoco, nitidezza

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

messa a fuoco automatica

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

distanza iperfocale, distanza di messa a fuoco iperfocale

the unintentional alteration of the shape or proportions of objects in a scene, caused by factors such as the curvature of the lens, the angle of view, and the distance to the subject

distorsione, deformazione

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

spettro elettromagnetico, spettro di radiazioni elettromagnetiche

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
