A

halation

29
Q

Its function is to chemically reduce the silver halide to metallic silver in various points where light has produced the latent image.

A

Reducing Agent

30
Q

Its function is to guard the developer against air oxidation.

A

Preservatives

31
Q

Its function is to increase the alkalinity of the developing solution, hence increase the activity of
most of the developing or reducing agents.

A

Accelerators

32
Q

Its function is to control the speed of the developer.

A

Restrainer

33
Q

is based upon the principles that the colors of nature can be adequately represented to the eye and brain by mixtures of BLUE, GREEN, and RED LIGHT.

A

COLOR PHOTOGRAPHY

34
Q

The use of Blue, Green, Re beams or filters is dificult and wasteful of lightful energy. Most methods are based on compliments of blue, red, and green, which are

A

YELLOW, MAGENTA, and CYAN

35
Q

yellow, magenta, cyan controlls what colors

A

YELLOW FILTER - controls blue ; permits green and red
MAGENTA FILTER - controls green ; permits blue and red
CYAN FILTER - controls red ; permits blue and green

36
Q

Dyes with properties suitable for color photography are produced when the development is accomplished by p-phenylenediamines in the presence of an active species called

A

Coupler

37
Q

Preparation of light-sensitive emulsion

A

• Silver halides are sensitive only to
wavelengths shorter than 500 nm.
• Orthochromatic Emulsion- sensitivity is increased to 600 nm.
• Panchromatic Emulsion- sensitivity is
increased to 700 nm.

38
Q

Manufacture of the
base or support for
the emulsion

A

Glass- precision photography
Plastic- Modern photography
Paper- print materials

39
Q

Coating of the emulsion
on the base

A

• The finished product consists of several separately applied emulsion layers.
• Intermediate layer is used to prevent stray
light from reflecting back.
• Color Films requires many layers of
emulsion.

40
Q

absorbs most of the light that would
otherwise be reflected back up
through the emulsion, scattering the
light and reducing sharpness in the image.

A

Gelatin Anti-Halation Layer

41
Q

prevent the tendency of the
film to curl when the emulsion
swells during processing.

A

Anti-Curl Backing

42
Q

solid sheets of thermoplastic or partially
cured (B-staged) thermosetting polymers
that can be cut to size and generally used
to attach large-area components,
substrates, and lids.

A

Adhesion Promotion Layer

43
Q

a thermosetting resins with high
cohesive strength and excellent adhesion
to metals, ceramics, glass, rubber, and
some plastics. They are generally rigid
and have excellent chemical resistance.
Epoxy film enables clean, consistent bond lines and manufacturing that
eliminates dispensing of liquids.

A

B-Stage Epoxy Film

44
Q

the layer of plastic that
supports the images, sound,
and other information
contained in the emulsion.

A

Film Base

45
Q

holds something in suspension. It is this
material in suspension that is sensitive to
radiation and forms the latent image on the
film.
