It is the result of double refraction from inner lens surfaces. It exhibits itself as a misty, hazy, or cloudy semi-circular path of life.

it is used effectively when photographing blood. When used outdoors, a blue filter will make the sky, or any blue object, appear white in the photograph.

It refers to spots on the film caused by stray light worn on shiny parts of the lens, such as the spots on the shutter, lens mount, or from inside the camera itself.

The taking of a photograph of an object in a very reduced size or tiny images of large object.

lens with flat side and one concave side

it is the focusing at different points of rays passing through different parts of a spherical lens.

it is used to photograph white cars; the details of the car will stand out. It also cut through haze to a certain extent and can be used with good results to photograph an accident on a hazy day.

TYPES OF LENS

It is used in the focusing assembly of the camera

Types of Zoom Lens

a mechanical assembly of lens elements for which the focal length (and thus angle of view) can be varied, as opposed to a fixed focal length (FFL) lens or prime lens.

It is the light-transmitting power of the lens at its maximum aperture, or f-stop setting

It can make the subject appears closer without changing the camera position

It occurs when light falling obliquely on the lens and passing through different circular zones

The eye of the camera is also the heart of the camera

a curved, concave, or saucer-shaped image of an object that has a flat surface.

a filter which screens out the violet end of the spectrum. It is placed in front of a lens and left there. It will not only improve most of the police photographer’s work, it will also prevent the lens from being scratched

They are used to change the composition of available light before allowing it to strike the film.

a lens effect that causes images to be sphered or "inflated

they differ in the way they are curved and, therefore, in the manner in which they refract light

a lens effect that causes images to pinched at their center.

the angle of view of the human eye which is _________

lens with both sides curving inward

lens with one flat side and convex side

It controls (a) magnification (the size of the image formed by the lens) and (b) angle of view (the amount of the scene shown on a given size of film).

Special Types of Lenses

is the closest distance at which the lens can be focused while keeping the object at infinity acceptably sharp, that is, the focus distance with the maximum depth of field

it is the failure of different colored light rays to focus after passing through a lens

These are filters which do not affect the color or tonal quality of the scene except for the sky. They can be used both for color and black-and-white films.

lens with both faces bulging outward

Is a disc of transparent glass generally bounded by two spherical surfaces capable of transforming an image

lens where the concave side is pronounced than the convex side.

a lens with a focal length about equal to the diagonal size of the film or sensor format is considered to be a normal lens.

simple lens generally produces aberrated images. It consists of two or more simple lens fitted together.

A type of lens with at least one surface curving inward. It spreads out those light rays that have been refracted through it.

a lens that is capable of producing a reproduction ration of 1:1. It is specifically designed for close-up work, with long barrel for close focusing and optimized for high reproduction ratios, and one of the most common tools of macrophotography.

is used to cut down light transmission. It does not affect the tonal quality of the scene.

This type of lens allows more of the scene to be included in the photograph, which is useful in architectural, interior, and landscape photography where the photographer may not be able to move farther from the scene to photograph it.

the size of the image produced by a lens depends upon several factors like camerato-subject distance and focal length.

Is a piece of transparent material made of glass or plastic with two (2) opposite symmetrical (proportional or well-balanced) surfaces or at least one curved surface

Are colored disks of glass or gelatin which when placed in front of a camera lens, stop one or another color of light from passing through and striking the film.

These are filters which do not affect the color or tonal quality of the scene except for the sky. They can be used both for color and black-and-white films.

a lens with a maximum aperture of f/2.8 or larger is a ________ because it delivers more light intensity to the focal plane, allowing a faster shutter speed.

A lens that is thicker at the edges than at the center

It allows a quick adjustment to give a wider or narrower field of vision

ultra-wide-angle lens that does not produce a rectilinear image is called a ________

It shows the subject in a way that is similar to the image seen by the naked eye

It gathers light rays and refracts them to meet at a certain point.

Police Filters For Police Photography

does not affect the transmitted colors in a way that will change its color temperature.

a lens with a maximum aperture of f/3.5 or smaller is a _________ because it delivers less light intensity and requires a slower shutter speed.

Types of Convex Lens

a lens with longer focal lengths that constrict the field of view and decrease the depth of field while greatly magnifying the image

Is the failure of light rays to focus properly after passing through a lens or being reflected from a mirror.

Taking of photograph through a microscope

It is the largest opening of the diaphragm that the light can pass through

it is the inability of the lens to bring horizontal and vertical lines in the subject to the same plane of focus in the image.

A type of lens with at least one surface curving outward. It is thicker in the middle than at the ends.

lens where the concave side is less pronounced than the convex side.

TYPE OF CONCAVE LENS

when there is a different magnification for the ray's angle.

The angle of view is 45 degrees to 60 degrees

is an extreme close-up photography, usually of very small subjects, in which the size of the subject in the photograph is greater than life size.
