Inside A Camera

Definitions:

1)Rangefinder- any of various instruments for determining the distance from the observer to a particular object, as for sighting a gun or adjusting the focus of a camera.

2)Parallax- the difference between the view of an object as seen through the picture-taking lens of a camera and the view as seen through a separate viewfinder.

3)Pentaprism- a prism  that has five faces, a pair of which are at 90° to each other; a ray entering one of the pair emerges from the other at an angle of 90° to its original direction: used especially in single-lens reflex cameras to reverse images laterally and reflect them to the viewfinder.

4)Pellicle- a thin, partially reflective coating, as on a beam splitter or pellicle mirror.

5) Aperture- an opening, usually circular, that limits the quantity of light that can enter an optical instrument.

6)Shutter- a mechanical device for opening and closing the aperture of a camera lens to expose film or the like.

7)Exposure- the fact or state of being exposed.

8)Depth of field- the range of distances along the axis of an optical instrument, usually a camera lens, through which an object will produce a relatively distinct image.

9)F-stop- the setting of an adjustable lens aperture, as indicated by an f number.

10)Focal length- the distance from a focal point of a lens or mirror to the corresponding principal plane.
