Definitions

1. Camera lens are made in a wide range of focal lengths. (Web site)
2. When a camera lens is focused at infinity, the rear principal point is exactly one focal length in front of the film. (Web site)
3. Inside every camera lens is an opening called the aperture which works in exactly the same way as the pupil in a human eye. (Web site)

Microlenses

1. Others replace the camera lens with an array of thousands of microlenses or with a virtual lens that exists only in software. (Web site)

Lens Works

1. The lens works much like a camera lens, focusing light onto the retina at the back of the eye. (Web site)

Camera Lens 106

1. Only the image light is directed toward a sensor 108 by a camera lens 106. (Web site)

Scene

1. In the single-lens reflex camera the photographer sees the scene through the camera lens. (Web site)

Reverse

1. Reversing rings (available at most camera stores) allow you to reverse your camera lens. (Web site)

Way

1. The way your camera lens collects and focuses light is governed by the physics of diffraction. (Web site)

Works

1. It works by tracing in reverse, a path that could have been taken by a ray of light which would intersect the imaginary camera lens.

Film

1. The adjustable opening in a camera lens that -like an eye's iris- controls the amount of light that reaches the film or digital sensor.

Optical System

1. An optical axis is a line along which there is some degree of rotational symmetry in an optical system such as a camera lens or microscope. (Web site)

Front

1. A lens attachment placed in front of a camera lens to permit taking pictures at a closer distance than the camera lens alone will allow.

Apertures

1. And the camera lens must be set to a specific aperture (or a small range of apertures) determined by the speed of the film in use.

Digital Camera

1. The ingenious ring connects your SWAROVSKI OPTIK EL or SLC series binoculars directly to your digital camera thus creating a camera lens.

Spotting Scope

1. Probably the wrong choice unless you want to use it as a spotting scope in the daytime, or as a camera lens.

Camera Body

1. Type of exposure meter built into the camera body and reading through the camera lens.

Field

1. If you take a picture of the moon with a camera lens that has the same field of view as Celestia, you may be surprised at the small size of its image. (Web site)

Photographic Lenses

1. In 1942 the Annexe started making photographic lenses for the RAAF. The problems presented by a camera lens are different from those of a telescope. (Web site)

Subject

1. The incident dome may not catch the light exactly the way the combination of the subject and camera lens. (Web site)

Light Source

1. The use of an optical filter for picture or color enhancement in front of the camera lens or light source.

Light Sources

1. Can be used over light sources or over the camera lens. (Web site)

Focal

1. Focal length: the distance from the middle of the camera lens to the focal plane (i.e.

Close

1. Do some test shots first and if the subject appears too light use exposure compensation to close the camera lens down by half to one stop. (Web site)

Extremely Close

1. This is important, because the onboard flash is extremely close to the camera lens. (Web site)

Focus

1. Standard close-up lenses, or diopters, are single element lenses that allow the camera lens to focus more closely on small objects.

Small Aperture

1. A camera lens adjusted for large and small aperture. (Web site)

Light Coming

1. The second is to measure the light coming off the subject in the direction of the camera lens: reflected metering. (Web site)
2. Light coming from behind the subject, toward the camera lens, so that the subject stands out vividly against the background.

Sigmoidoscope

1. A camera lens at the end of the sigmoidoscope sends pictures from the inside of your bowel to a monitor. (Web site)

Shutter

1. In order to avoid this, hold your hand over the camera lens while opening the shutter.

Autofocus

1. Autofocus - The camera lens focuses automatically, usually when the shutter release is half-pressed. (Web site)
2. Autofocus (AF) Camera system by which the camera lens or its body automatically focuses the image of a selected part of the picture subject. (Web site)

Cameras

1. Cameras with a separate optical viewfinder system show the scene from a different viewpoint from that of the camera lens. (Web site)

Camera

1. Avoid cameras where the camera lens extends out of the main camera body when the camera is switched on or zoomed in or cameras with large diameter lenses. (Web site)
2. As shown in FIG. 1C, when the camera is not used, the camera lens cap 43 is designed so as to cover over the camera lens 42. (Web site)

Light

1. By having the light come from the side, the reflected light is primarily in the direction of the strobe instead of the camera lens. (Web site)
2. The objective lens pulls in light from your surroundings similar to a camera lens. (Web site)
3. ApertureThe adjustable opening in a camera lens that -like an eye's iris- controls the amount of light that reaches the film or digital sensor.

F-Stop

1. The higher the f-stop the smaller the opening for the light to go through the camera lens. (Web site)

Lenses

1. The camera lens 42 can be formed of the combination of a plurality of lenses, but is formed of one lens in this embodiment. (Web site)
2. If you cut one open (don't try this at home, kids!), you'd find that such a camera lens contains a number of single "lenses" of different shapes and sizes.

Lens

1. Generally a simple positive (converging) lens used in front of the camera lens to enable it to focus at close range.
2. Teleconverters are multiple-element lenses that go between the camera lens and the body to increase the focal length of the lens. (Web site)
3. Lenses in the Lens A camera lens is actually several lenses combined into one unit. (Web site)

Camera Lens

1. The aperture is the camera's equivalent to the human eye and controls how much light enters through the camera lens. (Web site)
2. Colonoscopy - a test that uses a long, flexible tube with a light and camera lens at the end (colonoscope) to examine inside the large intestine.
3. The hole or opening formed by the metal leaf diaphragm inside the lens or the opening in a camera lens through which light passes to expose the film.
