APERTURE - The size of the lens
opening through which light passes.
AGITATE - To move a solution over the surface of film or paper during
development so that fresh liquid comes into contact with the surface.
ASA - A numerical rating that describes the sensitivity of film to light.
BRACKET - To make several exposures, some greater and some less than the
exposure that is calculated to be correct. Bracketing allows for error and permits
selection of the best exposure after development.
BURN IN - To darken a specific area of a print by giving it additional
printing exposure.
CAMERA - A picture taking device usually consisting of a light-tight box,
a film holder, a shutter to admit a measured quantity of light and a lens to focus the
image.
CASSETTE - A light-tight metal or plastic container that permits a roll
of 35mm film to be loaded into a camera in the light.
CONTACT PRINTING - Placing a negative in contact with sensitized
material, usually paper, and then passing light through the negative onto the material.
CONTRAST - The difference in darkness or density between one tone and
another.
CROP - To trim the edges of an image, often to improve the composition.
DEPTH-OF-FIELD - The small range of allowable focusing error which will
still produce an acceptable sharp image.
DEVELOPER - A chemical solution that changes the invisible, latent image
produced during exposure into a visible one.
EMULSION - A light-sensitive coating applied to photographic films or
papers. I consists of silver halide crystals and other chemicals suspended in gelatin.
EXPOSURE - The intensity of light multiplied by the length of time it
falls on a light-sensitive material; specifically, the combination of shutter speed and aperture.
FILM FORMAT - Negative size, such as 35 millimeter, 2 1/4" x 2
1/4", and 4" x 5".
FIXER - A chemical solution that makes a photographic image insensitive
to light.
F-STOP - The common term for the aperture setting of a lens.
SAFELIGHT - A light used in the darkroom during printing to provide
general illumination without giving unwanted exposure.
SINGLE-LENS REFLEX - A camera in which the image formed by the
taking lens is reflected by a mirror onto a ground-glass screen for viewing. The mirror
swings out of the way just before exposure; to let the image (or light) reach the film.
Abbreviated SLR.
SHUTTER - A mechanism that opens and closes to admit light into a camera
for a measured length of time.
SOLARIZATION - Reversed effect that occurs when film is grossly
overexposed in the camera. The term is commonly used to refer to the Sabattier effect.
STOP BATH - An acid solution used between the developer and the fixer to
stop the action of the developer and to preserve the effectiveness of the fixer.
WORKING SOLUTION - A chemical solution diluted to the correct strength
for use.
DODGE - To lighten an area of a print by shading it during part of the
printing exposure.
EASEL - Darkroom accessory used to hold printing paper flat and in place
under the enlarger.
EQUIVALENT EXPOSURE
- Alternative exposures settings (f-stops and shutter speeds)
that will produce proper exposure. The concept of equivalent
exposure will be discussed at length during class.
