To follow the motion of a moving object to look sharp and the background
Film that is sensitive to all (or almost all) wavelengths of the
visible spectrum. Abbreviated pan.
The difference in point of view that occurs when a lens (or other
device) from which the eye views scene is separate from the lens
that exposes the film.
connecter: See sync
terminal: The socket on
a camera or flash unit in which a PC connector (sync cord) is inserted.
The apparent size and depth of objects within an image.
An incandescent light that produces very bright light but has a
relatively short life.
An image produced by placing material directly onto a sheet of sensitized
film or printing paper and then exposing the sheet to light.
A composite image that is made by cutting out and assembling parts
of several photographs.
1.) A small clear spot on a negative, usually caused by dust on
the film during exposure or development or a small air bubble that
keeps developer from the film during development. 2.) The tiny
opening in a pinhole camera that produces the image.
of critical focus: The
part of a scene that is most sharply focused.
In early photographic processes, the sheet of glass or metal on
which emulsion was coated.
print: A film in which
the final image is formed in platinum rather than silver.
filter: A filter that reduces
reflections from non-metallic surfaces such as glass or water by
blocking light waves that are vibrating at selected angles of the
Any image with tones corresponding to those of the subject. Opposite:
An image with a flat, poster-like quality. High contrast lith film
is used to separate gray tones of a negative into a few distinct
shades of gray.
To soak film briefly in water prior to immersing it in developer.
camera: A camera that uses
sheet film, like a view camera, but which is equipped with a viewfinder
and a hand grip so it can be used without being mounted on a tripod.
Once widely used by press photographers, it has been replaced by
colors: Basic colors from
which all other colors can be mixed. See also: subtractive,
A photographic image, usually a positive one on paper.
frame: A holder designed
to keep sensitized material, usually paper, in full contact with
a negative during contact printing.
automatic: A mode of automatic
exposure in which the camera sets both the shutter speed and the
aperture that will produce the correct exposure.
printing: The process of
projecting an image of a negative onto sensitized material, usually
paper. The image may be projected to any size, usually larger than
An optical instrument for forming an enlarged image of a transparency
or a motion picture on a screen.
A test print made for the purpose of evaluating density, contrast,
color balance, subject composition and the like.
To expose film at a higher film speed rating than normal, then to
compensate in part for the underexposure by giving greater development
than normal. This permits shooting at a dimmer light level, a faster
shutter speed, or a smaller aperture than would otherwise be possible.
