Q

Sensitization to blue, green, and red is particularly important in the
representation of colors as shades of gray in black and white photography and
in their simulation in color photograph

A

true

36
Q

consists essentially of an emulsion on a film
support of cellulose acetate, polyester, or
glass

A

films and plates

37
Q

-composed of suspension of minute silver
halide crystals in gelatin
-suitably sensitized by the addition of certain
dyes
-antifogging agents, hardening agent

A

emulsion

38
Q

fogging of the emulsion by light reflected into
it from the back surface of the film is called

A

halation

39
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

40
Q

Its function is to guard the developer against air
oxidation.

A

preservatives

41
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

42
Q

Its function is to control the speed of the developer

A

45
Q

The processing of black-and-white
photographic materials is concluded
by a wash in still water to remove
the silver halides solubized by the
fixing baths.

A

false (running water)

46
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

47
Q

why use the compliments of blue, red, and green, which
are YELLOW, MAGENTA, and CYAN?

A

because The use of Blue, Green, Red beams or filters is difficult and wasteful of lightful
energy.

wavelengths shorter than 500 nm.

A

Silver halides

54
Q

increased to 600 nm.

A

Orthochromatic Emulsion-

55
Q

sensitivity is
increased to 700 nm.

A

Panchromatic Emulsion-

56
Q

is used to prevent stray
light from reflecting back.

A

Intermediate layer

57
Q

A

Gelatin Anti-Halation Layer
Anti-Curl Backing
Adhesion Promotion Layer
Film Base
Adhesion Promotion Layer
Emulsion Layer
Gelatin Protective Coating

59
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

60
Q

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

A

anti-curl backing

61
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

Adhesion Promotion Layer

62
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.

A

B-Stage Epoxy Film

63
Q

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

A

Film base

64
Q

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