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.

Extinction Meter

A device used in photographing minute objects. It is attached to the lens board of the camera and the lens is attached to it when close-up photographing is necessary.

Extension Tube

It is a transparent medium which transmits and absorbs different wave lengths of lights. They are usually made of glass or gelatin material placed in front or behind the camera lens.

Filter

It is a device used to eliminate some reflections of light which might destroy the image casts by the objects, especially, when the light is coming from the top or side portions of the camera.

Lens Hood

was the one who introduced the use of the lens in the camera. He made a large opening on his camera obscura and fitted into it a convex lens taken from the spectacles of a far sighted old man.

Daniel Barbaro

It is a convex lens, which is characterized by the fact that it is thicker at the middle than the edge and formed a real image on the opposite side of the lens

Positive Lens

it is a concave lens, which is characterized by the fact that it is thinner at the middle than the edge, then formed a virtual image on the same side of the lens.

Negative Lens

It is the failure of the lens to focus all the visible rays. The lens refracts rays of short wave length more strongly than those of longer wave length and therefore, brings blue rays to a shorter focus than red.

Chromatic Aberrations

The unequal magnifying power of different concentric zones of the lens causes this lens defect. It refers to aberration inherent to certain optical designs or due to imperfection in the lens or other components which results in off-axis point sources such as stars appearing distorted, appearing to have a tail, or coma, like a comet.

Coma

this aberration, the relation of the images of the different points is incorrect with respect to one another. The image on flat subject does not appear flat because of the sharpness of the center and the edge is out of focus.

Curvatures of Field

It is a combination of two achromatic lenses with almost the same focal length. This is corrected from some kinds of lens defects but not on astigmatism defect.

Rapid Rectilinear Lens

This is a lens which is free from astigmatism and other types of lens defects. It has the ability to focus a vertical and horizontal line at the same time.

Anastigmatic Lens

This is a lens which is partly corrected for chromatic aberration. An _____________is a lens that is designed to limit the effects of chromatic and spherical aberration. .

Achromatic Lens

A super corrected lens for astigmatism. It has a better color correction and has the ability to produce the best definition of image in the photographs.

Process Lens

A lens used in all fixed focus camera. Basically, it has a short focal length and greater depth of field. A photographic lens for which the focus is not adjustable is called a ____________ or sometimes focus-free.

Fixed Focus Lens

It is the distance measured from the axis of the lens through the film plane when the lens is focused at a distant object. Actually it determines

Focal Length

This is lens with a focal length less than the diagonal of the negative materials. It has a shorter focal length with large area coverage.

Wide Angle Lens

This is lens with a focal length approximately equal but not more than twice the length of the diagonal of the negative material. The angle of the view of this lens is 75 degrees but not less than 45 degrees.

Normal Lens

This is lens with focal length more than twice the diagonal of the negative material. It has a longer focal length with small area of coverage.

Telephoto Lens

are related to theory and methodology of composing or taking photographs, or to their manipulation during or after processing. This should not be confused with photographic processes, which comprise articles relating to the production of images using light-sensitive materials.

Techniques in photography

it is the pleasing arrangement of subject matter elements within the picture area. Creative photography depends foremost on the photographer’s ability to see as the camera sees because a photograph does not reproduce a scene quite the way we see it.

Photographic composition

This type of flash unit is fairly expensive compared with other types of flash, but has certain advantages. Its electronic flash tube can give thousands of flashes that augment the necessary lighting of the objects being photographed.

Electronic Flash Bulb

this makes the photographing of object easier than ever. It is plugged to a camera that has flash cubes socket.

Flash Bulbs

the final stage in making a photograph. If no such device is utilized the image of the negative is transferred to the photographic paper directly through contact process known as the contact printing.

Print making

one or more negatives are placed in intimate contact with a sheet of sensitized photographic paper

contact printing

it is a photographic image produced from film: sometimes from a film negative, and sometimes from a film positive

contact print

This is the opening of the lens that controls the rays of light passing through it.

Lens Aperture

This is responsible in forming the image coming from the negative. Basically, it bends the rays of light that passes through it and form the enlarged image.

Lens

This part controls the image size projected on the base. By raising or lowering the enlarger head, the image becomes bigger or smaller.

Elevating Control Knob

this supports the entire unit of the enlarger. Usually it holds the easels that carry the photographic paper. This can be attached directly to the counter top, and not be concerned with the base not being large enough, and falling off of it.

Base Board

referred to as crime scene photography, is an activity that records the initial appearance of the crime scene and physical evidence, in order to provide a permanent record for the courts.

Forensic photography

uses an electronic image sensor to record the image as a set of electronic data rather than as chemical changes on film.

Digital imaging

uses cameras containing arrays of electronic photodetectors to produce images focused by a lens, as opposed to an exposure on photographic film.

Digital Photography
