CHAPTER 5 Flashcards
This refers to colored disks of GLASS OR GELATINE which are placed in front of the camera lens to improve the quality of pictures
Filters
Uses of Filter:
- It can be used in two ways
- When it is placed over a lens, it does two things
Photographic Filters:
- Blue Filters
- Green Filters
- Yellow Filters
- Ultraviolet or UV Filters
- Neutral Density Filters
- Polarizing Filters
- Haze and Skylight Filters
- Correction Filters
This refers to photographic filters that are used EFFECTIVELY WHEN PHOTOGRAPHING BLOOD
Blue Filters
what Photographic Filters MOST USED IN police work
Blue Filters
This refers to photographic filters that are used in PLACE OF BLUE FILTERS FOR PHOTOGRAPHING BLOOD
Green Filters
what Photographic Filters BEST USED IN police work
Green Filters
This refers to photographic filters that are used to photograph
WHITE CARS
Yellow Filters
This refers to photographic filters that is USED TO SCREEN OUT THE VIOLET END of the spectrum
Ultraviolet Filters
it will PREVENT THE LENS FOR BEING SCRATCHED
Ultraviolet Filters
It is placed in front of a lens and left there; it will not only IMPROVE MOST POLICE PHOTOGRAPHER work
Ultraviolet Filters
This refers to photographic filters that are used to CUT DOWN LIGHT TRANSMISSION
Neutral Density Filters
They are also used to REDUCE THE LIGHT INTENSITY to prevent over exposure.
Neutral Density Filters
It does NOT AFFECT THE TONAL QUALITY of the scene
Neutral Density Filters
This refers to photographic a filter that is used primarily to
CONTROL LIGHT REFLECTED FROM HIGHLY POLISHED SURFACES, metallic objects and others
Polarizing Filters
It is very useful in photographing many DIFFERENT VEHICLE IN AUTO ACCIDENT
Polarizing Filters
This is the ONLY FILTER THAT INCREASE THE BLUE SATURATION in the sky in a color photograph without altering the remaining colors in the scene.
Polarizing Filters
This refers to photographic filters that are used to
REMOVE EXCESS BLUISHNESS from distant view outdoors
Haze and Skylight Filters
This refers to photographic filters that are intended to alter
the RESPONSE TO THE SPECTRAL SENSITIVITY in terms of the naked eye.
Correction Filters
It CONTROL COOL TONE AND WARM TONE
Correction Filters
This refers to the RATIO OF THE TIME EXPOSURE with or without filter.
Filter Factors
Filter factors depends upon the:
- Absorption characteristics of the filter
- Subject
- Spectral sensitivity of the emulsion
- Processing conditions
