Filmmaking Terms | Production (On Set) | Camera & Lighting | Part 1

 

camera = the device used to capture images for a film. lens = an optical device used with a camera to focus light and form an image on the sensor. aperture = the opening in a lens through which light passes, controlling the amount of light and depth of field. measured in f-stops. shutter speed = the duration for which the camera's sensor is exposed to light, affecting motion blur. ISO = a measure of a camera sensor's sensitivity to light. higher iso means more sensitivity but can introduce noise. depth of field = the range of distance in front of and behind the subject that appears acceptably sharp in a photograph or video. focus = the sharpness or clarity of an image. rack focus = a technique where the focus shifts from one subject to another within the same shot. deep focus = a technique where all elements in the foreground, mid-ground, and background are in sharp focus simultaneously. framing = the way a shot is composed within the camera's frame, including the position of subjects and objects. composition = the arrangement of elements within the frame to create an aesthetically pleasing and meaningful image. rule of thirds = a compositional guideline that divides the image into nine equal sections by two horizontal and two vertical lines, suggesting placing key elements along these lines or their intersections. headroom = the space between the top of a subject's head and the top of the frame. nose room = the space left in front of a subject who is moving or looking off-screen, giving them "room to move into." eye line = the direction in which a subject is looking, crucial for maintaining continuity in conversations between characters.
