digital photography Unit 1
wide angle lens - ansShrinks the object in front of it, by way of a shorter focal length
white balance - ansan adjustment that can be made to the color so that all whites appear white
and not yellow or blue in the photograph
TIFF - ansTagged Image File Format; a lossless file format
telephoto lenses - ansThose that magnify an image or make an object seem closer than it
really is.
speed - anstells the size of the grain in film
single lens reflex - anssemi-automatic movement of the mirror, which produces an exact
image in the view finder
shutter speed - ansthe length of time that light is let into the camera in order to expose the
film
shutter - ansopens and closes between the film and the lens, letting light in only when you
have told the camera to do so.
sensitivity - ansthe equivalent of film speed on a digital camera
raw - ansA file format that is offered on some digital cameras. this file saves the actual data
and they are not processed by the camera.
point and shoot camera - ansuses an optical view finder, rather than having the semi-
automatic mirror
pixel - ansthe smallest unit of the picture that can be controlled
pinhole camera - ansdoes not use a lens and has a very small aperture.
pentaprism - ans5 sided mirror whose job it is to flip the light from the image so that the
image appears right side up rather than the inverted image that first occurs
optical zoom - answorks like a telephoto lens; the image quality remains the same as the
image that is magnified
lens - ansa piece of glass or other transparent substance with curved sides for concentrating or
dispersing light rays
large and medium format cameras - ansuses a negative film size that is greater than the usual
35mm
