it is defined as the art or process of producing images of object upon a surface sensitive to the chemical action of light.

Photography

can be used to salvage certain photographs taken in color which are unsatisfactory in their original form; sometimes when presented as black-and-white or single- color-toned images they are found to be more effective.

Monochrome printing or electronic display

The first permanent color photograph was taken in 1861 using the three-color-separation principle first published by Scottish physicist ____________

James Clerk Maxwell

Autochrome, the first commercially successful color process, was introduced by the ___________

Lumière brothers

it is the subject matter discussed by physicists and chemists, which agreement as to the nature of light is still vague.

Light

Dutch physicist _____________ (1929-1695) had proposed the wave theory, based on the transmission of motion along the surface of water.

Christiaan Huygens

He proved that what the light men see as white is a mixture of all colors of the spectrum.

Isaac Newton

are lights which come to existence without the intervention of man,. is used for outdoor photography while artificial light is unlized in indoor photography to augment the adverse lighting condition.

Natural Lights

The sun is covered by the light clouds and the shadow appears bluish because of the decrease of light falling on the subjects in open space.

Hazy Sunlight

as opposed to natural light, refers to any light source that is produced by electrical means. Artificial lighting has many different applications and is used both in homes and commercially Artificial lights are available in a wide variety of shapes, sizes, colors of light emitted, and levels of brightness.

Artificial light

Also known as reflectorized light or spot light. This is so, because, this type of lamp needs a reflector to focus the light on the subjects. It can be a bulb with a built-in reflector or bulb which needs a reflector.

Photoflood Lamp

This is a special type of artificial light that is capable of producing infrared radiation.

Infrared Lamp

are designed to give a high intensity of infrared light and can be used conveniently with a flash gun.

Flash bulbs

These are chemical lamps as they generate lights by the rapid combustion of metal in oxygen.

Flash Bulbs

it Is a gas lamp burning disulphide vapor in oxygen or in nitric oxide., and is followed by several lamps designed to produce ultraviolet radiation, light, the mercury vapor light, the electric discharge lamps and the commercial lamps.

Ultraviolet Lamp

it is an integral part of the crime scene investigator’s search for evidence by enhancing the observation and collection of evidence including latent prints on smooth non-porous surfaces, bites, bruises, blood detection and shoe impressions.

Reflective Ultra Violet Imaging System

it is a compact, portable and rugged UV-visible tunable light source with 400W metal halide lamp

Mini-Crime Scope MCS-400

it contains minute grains of silver halide suspended in animal gelatin and coated on celluloid material.

Phot-films

It is sensitive to all colors, especially to blue and violet. It is suitable for general use in the preparation of black and white photographs.

Panchromatic Film

It is a special type of film which is sensitive to infrared radiation. It is also sensitive to violet and blue-green.

Infrared Film

This film is sensitive to all types of colors except red, and this type of film is popular in the market as the Kodalith film. anchromatic film.

Orthochromatic Film

It is a film specially treated that makes it more sensitive to blue rays of light. It is a type of photographic film which is only sensitive to light in the blue portion of the visible spectrum, or, in other words, light having a wavelength between 450 and 500 nanometers) and in the ultraviolet portion of the spectrum.

Blue Sensitive Film

means the range of illumination or the light is allowed to affect the sensitized materials at a given time.

Exposures

it is a number that represents a combination of a camera’s shutter speed and f-number, such that all combinations that yield the same exposure have the same EV, for any fixed scene luminance.

Exposure Value

may be defined as a light tight box, with a means of forming the image, or lens, with a means of holding sensitized material or film holder, and with a means of controlling the amount of light that will reach the film.

Camera

This part of the camera is very essential because of its capability to exclude all unwanted light that might expose the sensitized material or film.

Light Tight Box

it is responsible in focusing the rays of light coming from the subject. It is the most essential part of any cameras. Without the lens, the sharpness of the image formed on the film would be impossible

lens

served as the barrier of the rays of light that will enter and affect the film inside the camera.

shutter

will control the duration between the opening and the closing of the shutter. It will regulate the quantity of light that will reach and affect the film inside the camera

shutter speed

the ratio between the diameter and the focal length of the lens is called _________

Lens Aperture

The best way to determine the entire coverage of the camera is to look directly behind the lens of the camera.

Single Lens Reflex Type

This is attached to the shutter release of the camera and used in releasing the shutter to prevent accidental movement of the camera during the exposure period especially when longer exposure is made.

Cable Release

The reflected light from the shadow as seen by the naked eye is estimated or calculated by direct observation of the photographer.
