1
refers to films and papers that are composed of emulsion containing SILVER HALIDE crystals suspended in gelatin and coated on a transparent or reflective support
SENSITIZED MATERIAL
2
Part of the film or photographic paper which contains the silver grains that is sensitive to light.
EMULSION
3
Designed to hold back the light and prevents halation.
ANTI HALATION BACKING
4
Support the emulsion
BASE
5
A transparent Cellulose nitrate or cellulose acetate composition made in thin, flexible strips or sheets and coated with a light-sensitive emulsion for taking photographs
PHOTOGRAPHIC FILMS
6
basically composed of a light-sensitive coating (emulsion) on a paper base or support .
PHOTOGRAPHIC PAPER
7
an alteration in the spectral response of a photographic material brought about by a change in the spectral distribution of energy in the light source used for exposure is a difference in a relative brightness in which different colors are reproduced by the photographic materials
FILM AND LIGHT
8
is defined as the product of illumination and time.
EXPOSURE
9
made of gelatins or glass, are used in front of a camera lens to alter the color balance of light to change contrast or brightness, to minimize haze, or create special effects.
FILTERS
10
are used to control the relative tone values in which colors are rendered by the photographic process, to lighten or darkened particular colors or to obtain color separation records for color photography works.
COLOR FILTERS
11
are designed to show by direct observation the relative values in which color will be reproduced by a particular type of sensitized without or with a given filter.
VIEWING FILTER
12
Are used to reduce the light intensity to prevent over exposure
NEUTRAL DENSITY FILTER
13
are used primarily to control light reflected from highly polished surfaces, metallic objects and others
POLARIZING FILTER
14
Objects are distinguished from their surroundings by the contrast, which may be the result of a difference in brightness or color.
PRINCIPLE OF COLOR FILTER
15
a photographic material exposed to such filtered radiation will receive a small amount of light than one without any filter.
FILTER FACTOR
16
the result of photography in its final form is the photograph
SENSITIZED PAPER
17
contains silver chloride emulsion, grained and produce deep black images, used for contact printing.
SILVER CHLORIDE PAPER
18
contains silver bromide emulsion.Light sensitivity of this type is faster than the silver chloride paper.
SILVER BROMIDE PAPER
19
conbines the contrast ranges in one paper, it uses a special Chlorobromide emulsion that produce varying contrast responses upon exposure to different colored light.
VARIABLE CONTRAST PAPER
20
is the term used to describe the process of making positive images from negatives (and in some instances from film positives
PRINTING
21
is the process of making positive prints by placing a sheet of printing paper in direct contact with the negative, emulsion to emulsion.
CONTACT PRINTING
22
is made by passing light through the negative onto a piece of paper that is coated with a light-sensitive emulsion very similar to film
PHOTOGRAPHIC PRINT
23
it is the process of making a positive prints by projecting the negative images onto photosensitive paper.
PROJECTION PRINTING
24
removal of parts of an image in order to improve the image's composition.
CROPPING
25
this allows you to apply local exposure control to bring out more details in the highlight and shadow areas.
DODGING OR BURNING IN
26
blocking a portion of the light when printing a photograph so that an area of the print will be made lighter.
DODGING
27
Also known as Printing in.
BURNING
28
you can change the appearance of the image by use of diffusers or patterns between the lens and paper.
SPECIAL EFFECTS
29
is the deivice used to hold the paper during exposure.
EASEL
30
are similar in design and operation
ENLARGERS
31
it has a set of condensing a lenses between the printing light and the negative.
CONDENSER ENLARGER
32
has a diffusing medium between the light source and the negative to spread the light evenly over the entire surface of the negative.
DIFFUSION ENLARGER
33
can be carried out in trays, tank, or mechanized equipment
FILM PROCESSING
