CHAPTER 6 Flashcards
This refers to a CELLULOSE TAPE OR PLATE where silver salts are suspended that are capable of recording light
Film
This refers to TOP LAYER SCRATCH – RESISTANT COATING; gelatine coating; an over – coating composed of a thin transparent layer of hard gelatine which helps protect the silver halide emulsion from scratches and abrasions
Top Coating
Structure of Black – and – white film:
- Top Coating
- Emulsion Layer
- Film Base
- Anti – Curl
- Structure of Color Film
This refers to structure of film that is made of cellulose acetate or other materials such as PAPER, PLASTIC OR GLASS which supports the emulsion layer and is coated with a non – curl anti – halation backing.
Film Base
it absorbs light that may penetrate the emulsion layer to PREVENT IT FROM REFLECTING BACK TO THE EMULSION thus making the mage sharper since it suppresses double image, and prevents the appearance of halo formation in the photograph
Anti – Curl
Type OF Monochromatic Film:
1.Blue Sensitive Film
2.Ultra – Violet Sensitive Film
This refers to structure of film that composed
of SILVER HALIDES AND GELATINE
Emulsion Layer
This refers to a BLACK DYE applied on the
rear surface of the film
Anti – Curl
According to Spectral Sensitivity (Color Sensitivity):
- Monochromatic Film
- Panchromatic Film
- Orthochromatic Film
- Infrared Film
This refers to film that is sensitive to a single color
of light
Monochromatic Film
This refers to emulsion layer that CONSIST THREE OR FOUR LAYERS stacked one on top of another with filter in between each.
Structure of Color Film
This refers to film that is MORE SENSITIVE TO BLUE rays of light.
Blue Sensitive Film
This refers to film that is SENSITIVE TO UV RAYS ONLY
Ultra – Violet Sensitive Film
This refers to film that is sensitive TO ULTRA VIOLET RAYs, AND ALL LIGHT found in the visible spectrum, especially to blue and violet light, suitable for general use in the preparation of BLACK AND WHITE PHOTOGRAPHS
Panchromatic Film
MOST COMMONLY USED IN INVESTIGATIVE PHOTOGRAPHY because it produces the most natural recording of colors
Panchromatic Film
This refers to film that is sensitive to UV rays, blue and green colors but NOT TO RED.
Orthochromatic Film
REDS ARE RECORDED AS DARK TONE, while greens and
blues as light tones when printed
Orthochromatic Film
This type of film is popular in the market as the KODALITH FILM
Orthochromatic Film
Two Main Types of Color Film:
- Color Reversal of Color Film
- Color Negative Film
This sensitivity is expressed in numerical RATING AS ASA
Exposure Index.
Film Speed
This refers to film that is SENSITIVE TO INFRARED and ultra
– Violet radiation, which is beyond the human eye’s sensitivity,
Infrared Film
SENSITIVE TO ALL COLORS found in the spectrum, and useful in penetrating haze because of its longer wavelength
Infrared Film
This refers to FILM SENSITIVE TO LIGHT
Film Speed
Speed Rating – Types of speed ratings:
- ASA
- DIN
- ISO
ASA MEANS
Americal Standards Association
Film Sizes:
- 110
- 120
- 126
- 135
- 220
ISO MEANS
Combination of ASA and DIN
DIN MEANS
Deutche Industries Normen
This refers to film sizes for CARTRIDGE LOADING POCKET cameras
110
This refers to film sizes that give a picture that measure about 2/14 INCHES WIDE
120
This refers to film sizes that is OLDER AND LARGER CARTRIDGE loading type,
126
This refers to film sizes that are commonly known as 35mm, so named because the film is 35MM WIDE
135
It was originally for motion pictures and the size USED IN COMMERCIAL theatres.
135
This refers to film sizes that are the same as 120’S BUT YIELDS TWICE MANY EXPOSURES
220
