a black and white film is basically made up of emulsion gray or antihalation backing and a support base

consist of crystals of light sensitive compounds evenly distribute throughout plastic based material

the layer is placed between the emulsion and the plastic based on a film to prevent whatever the light that posses through the emulsion and reflected by the base back to the emulsion which forms a halo

generally film based are made up of plastic material they serve as a support to the emulsion

express in arithmetic value system

express in logarithmic value system

express in combination of asa and din ratings

sensitive to ultraviolet rays and blue light only

sensitive to uv rays to blue and green color not sensitive to red

sensitive to ultraviolet radiation to blue green and red lights and or all colors

sensitive to ultraviolet rays to blue green red light and infrared rays

this refers to the size of the metallic silver grains that are formed after development of an exposed film

is the multilayer emulsion coated on the same support or base

this film yields either a negative or a positive image depending on how it is used

this film when process a positive image or transparency for projection viewing

is a light tight box with a lens to form an image with a shutter and diaphragm to control the entry of the image

it's rigid body design accepts a wide variety of lenses viewers film box and accessories

this type of camera digitalize the image which can then be put into a computer and enhance through a software package such adobe photoshop

this cameras limited number of image it can capture

this camera allow user to load and replace a variety of storage cards in match the same fashion as film is exposed and replaced with a new film

produce are taken by a digital camera can be viewed in a computer monitor or tv set for hard copies of such image a computer printer is used

serves multiple uts viewfinder control panel and instant playback monitor

although generally not necessarily but it is required for backlighted subjects or in a really low light level

wide angle normal telephoto even

where you can record audio chips such as short description of the image taken or noise in the surrounding area

that can see around corners

is a small or tiny hole which produces an image entirely free from distortion but its image is so dim that it is impractically long even if the fastest film is used

image formed by this method is simply the shadow of an object

it is considered as the smallest and simplest type of camera

it is a type of camera best suited for police where you to its interchangeability of the lens

a type of camera with dual lens one for focusing and the other for forming the image

is considered the biggest and expensive type of camera used for movie making

is the image forming device of the lens that actually has a greater effect on the quality of the image to be formed

is the distance measured from the optical center of the lens is set to focus at infinite position

with focal length not longer than the diagonal half of the negative

with focal length approximately equal but no longer than twice the diagonal half of the negative

with focal length longer than twice the diagonal half of the negative

lens with variable focal length or that which can be adjusted continuously by the movement of one or more elements in the lens system

is the distance measured from the nearest to the farthest object in a apparent sharp focus

is the nearest distance at which when a lens is focus with a given particular diaphragm of feeding will gives the maximum depth of field

is the setting of the proper distance in order to form a sharp image

help detect hidden evidence

done at low angles using a flashlight

used to capture small objects such as trace evidence

this cameras contain arrays of electronic photo detectors

wide format photography

covering the entire area

first step is to secure the crime scene

photographer should evaluate the available light and weather conditions

take photographs before anything is disturbed

next series of shot should be included the victims

each piece of evidence should be photographed

important to prove that no one has tampered the crime scene

series of shot should be repeated

photographer must work quickly

photographer can go back to document the victims injuries

responsible for examining issued equipment

is not waterproof and therefore moisture should be avoided

used to document the location condition and patterns

used for documentation of known source exemplar standards

photographs should provide information concerning the manner and cost of death of the victim

to help explain how the crime took place show from several angle
